SAFETY CONSIDERATIONS

Installation and servicing of air-conditioning equipment can

be hazardous due to system pressure and electrical compo-

nents. Only trained and qualified service personnel should

install, repair, or service air-conditioning equipment.

Untrained personnel can perform basic maintenance func-

tions of cleaning coils and filters and replacing filters. All

other operations should be performed by trained service per-

sonnel. When working on air-conditioning equipment, observe

precautions in the literature, tags and labels attached to the

unit, and other safety precautions that may apply.

Follow all safety codes. Wear safety glasses and work gloves.

Use quenching cloth for unbrazing operations. Have fire

extinguishers available for all brazing operations.

INSTALLATION

Unit is shipped in the vertical discharge configuration. To

convert to horizontal configuration, remove screws from side

duct opening covers and remove covers. Using the same

screws, install covers on vertical duct openings with the

insulation side down. Seals around duct openings must be

tight. See Fig. 2.

Confirm before installation of unit that voltage, amperage

and circuit protection requirements listed on unit data plate

agree with power supply provided.

I. STEP 1 — PROVIDE UNIT SUPPORT

A. Roof Curb

Assemble and install accessory roof curb in accordance with

instructions shipped with curb. See Fig. 3. Install insulation,

cant strips, roofing felt, and counter flashing as shown. Duct-

work must be attached to curb. If gas or electrical connections

are to be routed through the curb, attach the accessory thru-

the-curb service connection plate to the roof curb in accor-

dance with the accessory installation instructions. Connec-

tions must be installed before unit is set on roof curb.

IMPORTANT: The gasketing of the unit to the roof curb is

critical for a watertight seal. Install gasket supplied with the

roof curb as shown in Fig. 3. Improperly applied gasket can

also result in air or water leaks and poor unit performance.

Curb should be level. Unit leveling tolerances are shown in

Fig. 4. This is necessary for unit drain to function properly.

Refer to Accessory Roof Curb Installation Instructions for

additional information as required.

If gas or electrical connections are to be routed through the

bottom of the unit, attach accessory thru-the-bottom service

connections to the basepan in accordance with the accessory

installation instructions.

CAUTION: Ensure voltage listed on unit data plate

agrees with electrical supply provided for the unit.

WARNING: Disconnect gas piping from unit when

leak testing at pressure greater than 1/2 psig. Pres-

sures greater than 1/2 psig will cause gas valve damage

resulting in hazardous condition. If gas valve is ever

subjected to pressure greater than 1/2 psig, it must be

replaced before use. When pressure testing field-

supplied gas piping at pressures of 1/2 psig or less, a

unit connected to such piping must be isolated by man-

ually closing the gas valve(s).

WARNING: Before performing service or mainte-

nance operations on unit, turn off main power switch

to unit and install lockout tag. Electrical shock could

cause personal injury.

B. Alternate Unit Support

When the curb or adapter cannot be used, support unit with

sleepers using unit curb or adapter support area. If sleepers

cannot be used, support long sides of unit with a minimum of

three 4-in. x 4-in. pads, two at the corners and one at the

unit’s center of gravity. If more than 3 pads are used, equally

space them along the side.

C. Slab Mount (Horizontal Units Only)

Provide a level concrete slab that extends a minimum of 6 in.

beyond unit cabinet. Install a 6-in. gravel apron in front of

condenser coil air inlet to prevent grass and foliage from

obstructing airflow.

NOTE: Horizontal units may be installed on a roof curb if

required.

II. STEP 2 — FIELD FABRICATE DUCTWORK

Secure all ducts to roof curb and building structure on verti-

cal units. Do not connect ductwork to unit. For horizontal

applications, field-supplied flanges should be attached to

horizontal discharge openings and all ductwork secured to

the flanges. Insulate and weatherproof all external duct-

work, joints, and roof openings with counter flashing and

mastic in accordance with applicable codes.

Ducts passing through an unconditioned space must be insu-

lated and covered with a vapor barrier.

If a plenum return is used on a vertical unit, the return

should be ducted through the roof deck to comply with appli-

cable fire codes.

A minimum clearance is not required around ductwork. Cab-

inet return-air static shall not exceed –.30 in. wg with

EconoMi$er+ or .45 in. wg without economizer.

These units are designed for a minimum heating operation

continuous return-air temperature of 50 F (dry bulb), or an

intermittent operation down to 45 F (dry bulb), such as when

used with a night set-back thermostat.

To operate at lower return air temperatures, a field-supplied

outdoor-air temperature control must be used to initiate both

stages of heat when the temperature is below 45 F. Indoor

comfort may be compromised when these lower air tempera-

tures are used with insufficient heating temperature rise.

III. STEP 3 — INSTALL EXTERNAL TRAP FOR CONDEN-

SATE DRAIN

The unit’s 3/4-in. condensate drain connections are located on

the bottom and side of the unit. Unit discharge connections

do not determine the use of drain connections; either

drain connection can be used with vertical or horizontal

applications.

When using the standard side drain connection, make sure

the plug (Red) in the alternate bottom connection is tight

before installing the unit.

To use the bottom drain connection for a roof curb installa-

tion, relocate the factory-installed plug (Red) from the

bottom connection to the side connection. See Fig. 5A. The

piping for the condensate drain and external trap can be

completed after the unit is in place.

All units must have an external trap for condensate drain-

age. Install a trap a minimum of 4-in. deep and protect

against freeze-up. If drain line is installed downstream from

the external trap, pitch the line away from the unit at 1 in.

per 10 ft of run. Do not use a pipe size smaller than the unit

connection (3/4 in.). See Fig. 5B.

The center drain plug looks like a star connection, however it

can be removed with a 1/2 in. socket drive extension.

IV. STEP 4 — RIG AND PLACE UNIT

Inspect unit for transportation damage. File any claim with

transportation agency. Keep unit upright and do not drop.

Spreader bars are not required if top crating is left on unit.

Rollers may be used to move unit across a roof. Level by

using unit frame as a reference. See Tables 1A and 1B and

Fig. 6 for additional information. Operating weight is shown

in Table 1 and Fig. 6.

Lifting holes are provided in base rails as shown in Fig. 1

and 6. Refer to rigging instructions on unit.

CAUTION: All panels must be in place when rig-

ging and lifting.

A. Positioning

Maintain clearance around and above unit to provide mini-

mum distance from combustible materials, proper airflow,

and service access. See Fig. 1A and 1B Notes.

Do not install unit in an indoor location. Do not locate unit

air inlets near exhaust vents or other sources of contami-

nated air.

Be sure that unit is installed so that snow will not block the

combustion intake or flue outlet.

Unit may be installed directly on wood flooring or on Class

A, B, or C roof-covering material when roof curb is used.

Although unit is weatherproof, guard against water from

higher level runoff and overhangs.

Position unit on roof curb so that the following clearances are

maintained: 1/4-in. clearance between roof curb and base

rails on each side and duct end of unit; 35/16-in. clearance

between roof curb and condenser section end. (See Fig. 3,

section C-C.)

Locate mechanical draft system flue assembly at least 48 in.

from an adjacent building or combustible material. When

unit is located adjacent to public walkways, flue assembly

must be at least 7 ft above grade.

Flue vent discharge must have a minimum horizontal clear-

ance of 48 in. from electric and gas meters, gas regulators,

and gas relief equipment.

Flue gas can deteriorate building materials. Orient unit so

that flue gas will not affect building materials.

Adequate combustion-air space must be provided for proper

operation of this equipment. Be sure that installation com-

plies with all local codes and Section 5.3, Air for Combustion

and Ventilation, NFGC (National Fuel Gas Code), ANSI

(American National Standards Institute) Z223.1-latest year

and addendum Z223.1A-latest year. In Canada, installation

must be in accordance with the CAN1. B149.1 and

CAN1.B149.2 installation codes for gas burning appliances.

V. STEP 5 — INSTALL FLUE HOOD

Flue hood is shipped screwed to the burner compartment

access panel. Remove from shipping location and, using

screws provided, install flue hood and screen in location

shown in Fig. 7.

VI. STEP 6 — INSTALL GAS PIPING

Unit is equipped for use with type of gas shown on name-

plate. Refer to local building codes, or in the absence of local

codes, to ANSI Z223.1-latest year and addendum Z223.1A-

latest year entitled National Fuel Gas Code. In Canada,

installation must be in accordance with the CAN1.B149.1

and CAN1.B149.2 installation codes for gas burning appli-

ances when installing gas piping.

For natural gas applications, gas pressure at unit gas con-

nection must not be less than 4.0 in. wg (5.0 in. wg in high

heat units) or greater than 13.0 in. wg while unit is operat-

ing. For liquid propane applications, the pressure must not

be less than 5.0 in. wg or greater than 13.0 in. wg at the unit

connection.

Size gas supply piping for 0.5 in. wg maximum pressure drop.

Do not use supply pipe smaller than unit gas connection.

Support gas piping as shown in the table in Fig. 8. For exam-

ple, a 3/4-in. gas pipe must have one field-fabricated support

beam every 8 ft.

See Fig. 8 for typical pipe guide and locations of external

manual gas shutoff valve.

NOTE: If field-installed thru-the-bottom connections are

used, refer to the accessory installation instructions for

power wiring and gas connections. Refer to Fig. 1A and 1B

for drilling holes in basepan.

VII. STEP 7 — MAKE ELECTRICAL CONNECTIONS

A. Field Power Supply

All units except 208/230-v units are factory wired for the

voltage shown on the nameplate. If the 208/230-v unit is to

be connected to a 208-v power supply, the transformer must

be rewired by moving the black wire from the 230-v 1/4-in.

male spade terminal on the transformer and connecting it to

the 208-v 1/4-in. male spade terminal from the transformer.

Refer to unit label diagram for additional information. Pig-

tails are provided for field service.

When installing units, provide a disconnect per NEC. Use

copper conductors only when splice connectors are used.

All field wiring must comply with NEC and local require-

ments. In Canada, electrical connections must be in accor-

dance with CSA (Canadian Standards Association) C22.1

Canadian Electrical Code Part One.

Install conduit through side panel openings indicated in

Fig. 1A and 1B. Route power lines through connector to ter-

minal connections as shown in Fig. 9.

On 3-phase units, voltages between phases must be balanced

within 2% and the current within 10%. Use the formula

shown in Tables 2A and 2B, Note 2 to determine the percent-

age of voltage imbalance. Operation on improper line voltage

or excessive phase imbalance constitutes abuse and may

cause damage to electrical components. Such operation

would invalidate any applicable Bryant warranty.

NOTE: If field-installed thru-the-bottom connections are

used, refer to the accessory installation instructions for

power wiring and gas connections. Refer to Fig. 1A and 1B

for drilling holes in basepan.

B. Field Control Wiring

Install a Bryant-approved accessory thermostat assembly

according to installation instructions included with the

accessory. Locate thermostat assembly on a solid wall in the

conditioned space to sense average temperature in accor-

dance with thermostat installation instructions.

NOTE: For wire runs up to 50 ft, use no. 18 AWG (American

Wire Gage) insulated wire (35 C minimum). For 50 to 75 ft,

use no. 16 AWG insulated wire (35 C minimum). For over

75 ft, use no. 14 AWG insulated wire (35 C minimum). All

wire larger than no. 18 AWG cannot be directly connected to

the thermostat and will require a junction box and splice at

the thermostat.

CAUTION: When installing gas piping to gas valve

inlet, use properly sized back-up wrench on inlet flange

flats to prevent valve damage.

WARNING: Unit cabinet must have an uninter-

rupted, unbroken electrical ground to minimize the

possibility of personal injury if an electrical fault

should occur. This ground may consist of electrical wire

connected to unit ground lug in control compartment,

or conduit approved for electrical ground when

installed in accordance with NEC (National Electrical

Code), ANSI/NFPA (National Fire Protection Associa-

tion), latest edition, and local electrical codes. Do not

use gas piping as an electrical ground. Failure to follow

this warning could result in the installer being liable

for personal injury of others.

Route thermostat cable or equivalent single leads of colored

wire from thermostat subbase terminals to low-voltage con-

nections on unit (shown in Fig. 10) as described in Steps 1-4

below.

If unit is mounted on roof curb and accessory thru-the-curb

service plate connection is used, route wire through connec-

tion plate.

Pass control wires through the hole provided on unit (see

connection D in Connection Sizes table in Fig. 1A and 1 B).

Feed wires through the raceway built into the corner post to

the 24-v barrier located on the left side of the control box.

See Fig. 11. The raceway provides the UL-required (Under-

writers’ Laboratories) clearance between high- and low-

voltage wiring.

Connect thermostat wires to screw terminals on low-voltage

connection board.

POWER EXHAUST ELECTRICAL DATA

N/A—Not available

NOTE: If a single power source is to be used, size wire to include power

exhaust MCA and MOCP. Must be in accordance with NEC or local

codes.

Check MCA and MOCP when power exhaust is powered through the

unit. Determine the new MCA including the power exhaust using the fol-

lowing formula:

MCA New = MCA unit only + MCA of Power Exhaust

For example, using a 580FPV090 unit with MCA = 40.1 and MOCP

= 45, with CRPWREXH030A00 power exhaust.

MCA New = 40.1 amps + 1.6 amps = 41.7 amps

If the new MCA does not exceed the published MOCP, then MOCP

would not change. The MOCP in this example is 45 amps and the MCA

New is below 45; therefore the MOCP is acceptable. If “MCA New” is

larger than the published MOCP, raise the MOCP to the next larger size.

For separate power, the MOCP for the power exhaust will be 15 amps

per NEC.

NOTES:

1. In compliance with NEC requirements for multimotor and combina-

tion load equipment (refer to NEC Articles 430 and 440), the overcur-

rent protective device for the unit shall be fuse or HACR breaker.

Canadian units may be fuse or circuit breaker.

2. Unbalanced 3-Phase Supply Voltage

Never operate a motor where a phase imbalance in supply voltage is

greater than 2%.

Use the following formula to determine the percent

of voltage imbalance.

%Voltage Imbalance

Example: Supply voltage is 460-3-60.

AB = 452 v

BC = 464 v

AC = 455 v

= 457

Determine maximum deviation from average voltage.

(AB) 457 – 452 = 5 v

(BC) 464 – 457 = 7 v

(AC) 457 – 455 = 2 v

Maximum deviation is 7 v.

Determine percent of voltage imbalance.

%Voltage Imbalance = 100 x

= 1.53%

This amount of phase imbalance is satisfactory as it is below the

maximum allowable 2%.

IMPORTANT: If the supply voltage phase imbalance is more than 2%,

contact your local electric utility company immediately.

C. EconoMi$er+ Control Mode

Determine the EconoMi$er+ control mode before installing

sensors and accessories. Different sensors are required for

different control modes, and a number of accessories are

available. Refer to Tables 3 and 4.

Outdoor Dry Bulb Changeover

The standard control mode for the EconoMi$er+ is Outdoor

Dry Bulb Changeover. The outdoor air and supply air tem-

perature sensors are also included as standard.

EconoMi$er+ control is based on the outdoor temperature

relative to a set point in the software. If the outdoor-air tem-

perature is above the set point then the EconoMi$er should

be in minimum position. If the outdoor-air temperature is

below the set point, the position should be controlled to

maintain the leaving air temperature set point. The set point

range is 45 to 70 F.

Differential Dry Bulb Changeover

The control supports differential dry bulb changeover con-

trol. This requires an accessory return air temperature

sensor CRTEMPSN001A00 installed in the return air-

stream. Refer to the Start-up section for details on how to

configure and enable the control mode. The user can check

the operation of the sensor using the Read function.

Outdoor Air Enthalpy Changeover

The control supports outdoor air enthalpy changeover control.

This mode requires a factory-supplied outdoor air temperature

sensor (OAT) and an accessory outdoor air humidity sensor

(ORH) (part no. CRHUMDSN001B00). Refer to the Start-Up

section for details on how to configure and enable the control

mode. The user can check the operation of the sensors using

the Read function.

Differential Enthalpy Changeover

The control supports differential enthalpy changeover con-

trol. This requires the factory-supplied outdoor air tempera-

ture sensor, an accessory outdoor air humidity sensor, an

accessory return air temperature sensor, and an accessory

indoor air humidity sensor. Refer to the Start-Up section for

details on how to configure and enable the control mode. The

user can check the operation of the sensors using the Read

function.

D. Damper Movement

When the EconoMi$er+ board receives initial power, it will

take the damper up to 21/2 minutes before it begins to posi-

tion itself. After the initial positioning, subsequent changes

to damper position will take up to 30 seconds to initiate.

Damper movement from full open to full closed (or vice

versa) takes 21/2 minutes.

If the damper is in the process of changing positions (for

example it is trying to open to 100%) and the fan signal is

turned off, the damper will continue to its 100% open posi-

tion before closing.

NOTE: Occupied minimum position can not be set lower than

+1% higher than the value of IAQ minimum economizer posi-

tion. Refer to the setup examples on page 56.

E. EconoMi$er+ Controller Wiring

The EconoMi$er+ is supplied from the factory with a supply

air temperature sensor and an outside air temperature

sensor. This allows for operation of the EconoMi$er+ with

outdoor air dry bulb changeover control. Additional accesso-

ries can be added to allow for different types of change over

control and operation of the EconoMi$er+ and unit.

F. Thermostats

The EconoMi$er+ control works with conventional thermo-

stats that have a Y1 (cool stage 1), Y2 (cool stage 2), W1 (heat

stage 1), W2 (heat stage 2), and G (fan). The EconoMi$er+

control does not support sensor thermostats like the T56 and

T57. Connections are made at the thermostat terminal con-

nection board located in the main control box.

Table 4 — EconoMi$er+ Field-Installed Accessories

*5-pin sensor wiring plug accessory (P/N CRE+PLUG001A00) is

required to install IAQsensor.

G. Outdoor Air Temperature (OAT)Sensor (Provided)

The outdoor air temperature sensor is a 10K thermistor used

to measure the outdoor-air temperature. The sensor controls

EconoMi$er+ changeover and compressor lockout. The sensor

is factory-installed on the EconoMi$er+ in the outdoor air-

stream. The operating range of temperature measurement is

0° to158 F. See Tables 5 and 6 for thermistor resistance and

resolution values.

The temperature sensor looks like an eyelet terminal with

wires running to it. The sensor is located in the “crimp end”

and is sealed from moisture.

The user can read the value of the sensor using the Read

mode, described in the Start-Up section.

H. Supply Air Temperature (SAT)Sensor (Provided)

The supply air temperature sensor is a 10K thermistor

located at the inlet to the indoor fan. This sensor must be

field installed. The operating range of temperature measure-

ment is 0° to158 F. See Tables 5 and 6 for thermistor resis-

tance and resolution values.

The temperature sensor looks like an eyelet terminal with

wires running to it. The sensor is located in the “crimp end”

and is sealed from moisture.

The user can read the value of the sensor using the Read

mode, described in the EconoMi$er+ Controller section.

I. Indoor Air Quality (IAQ) Sensor

Any indoor air quality or CO2 sensor that provides a 4 to

20 mA output can be used as the IAQ sensor. The controller

will modulate the outdoor-air damper to provide ventilation

based on the sensor output and the IAQ setting of the control-

ler. The CO2 sensor will modulate the outdoor-air damper from

the minimum position (IAQ minimum damper position set

point) to the maximum position (occupied minimum damper

position). When there is no CO2 call, the damper will go to the

unoccupied minimum position. When there is a CO2 call, the

damper will be between the IAQ minimum economizer set

point position and the occupied minimum damper position.

Mount the sensor according to manufacturer specifications.

In order to wire this sensor, an accessory 5-pin plug (part

number CRE+PLUG001A00) is required. See Fig. 22.

The IAQ sensor is wired to the ground and IAQ wires in the

harness. The accessory 5-pin wiring plug is connected to pins

13-17 of J3 on the EconoMi$er+ controller. Push the plug

down onto the pins of the EconoMi$er+ controller to install.

Pins 13 and 14 are used for the IAQ sensor. Pins 15-17 are

used for the field-installed remote potentiometer. Connect

the IAQ sensor to the BRN and WHT wires of the accessory

5-pin plug.

NOTE: Pin numbers are not shown on the controller. They are

provided only as reference for the installer. On the

EconoMi$er+ board, they numbered 1-17 from left to right, but

only the 1 and the 17 are printed on the board.

Sensor wiring should be extended with wire and wire nuts

and routed to the IAQ sensor location. Adjust the IAQ set-

ting at the controller to correspond to the IAQ voltage output

of the sensor at the user-determined set point. See Fig. 26.

Power the sensor with a field-supplied transformer.

J. Return Air Temperature (RAT)Sensor

The EconoMi$er+ controller will accept input from the acces-

sory 10K return air temperature sensor (CRTEMPSN001A00)

in addition to the outdoor air temperature sensor shipped

with the EconoMi$er+. By using both sensors, the outdoor air

and the return air temperatures are compared (differential

dry bulb) for optimal energy savings. See Tables 5 and 6 for

thermistor resistance and resolution values.

The temperature sensor looks like an eyelet terminal with

wires running to it. The sensor is located in the “crimp end”

and is sealed from moisture.

The user can read the value of the sensor using the Read

mode, described in the EconoMi$er+ Controller section.

Mount the return air temperature sensor on the EconoMi$er+,

through pre-punched holes. See Fig. 27.

The return air temperature (RAT) sensor is provided with a

2-wire, 42-in. long wiring harness with a 2-pin connector.

The plug is installed on pins 5 and 6 on J3 of the

EconoMi$er+ controller. The pins are labeled with a ground

symbol and RAT on the EconoMi$er+ controller. See Fig. 22.

The red wire of the harness is connected to pin 5 (ground).

The black wire of the harness is connected to pin 6 (RAT).

The wiring harness should be routed from the EconoMi$er+

controller to the sensor. The controller compares the temper-

atures of the two airstreams, chooses the best one, and mod-

ulates the EconoMi$er+ actuator accordingly.

This 10K thermistor is used to measure the return air

temperature vs. resistance curve, per Table 5. The range of

temperature measurement is between 0° and 158 F. See

Table 6 for resolution.

K. Outdoor Air Humidity Sensor

The EconoMi$er+ controller accepts input from the accessory

outdoor air humidity sensor in addition to the outdoor air tem-

perature sensor shipped with the EconoMi$er+. By using both

sensors, the total enthalpy of the outside air is calculated.

Mount the outdoor-air humidity sensor in to the

EconoMi$er+, through the pre-punched holes. See Fig. 28.

The outdoor-air humidity sensor is provided with a 2-wire,

42-in. wiring harness with a 2-pin connector. The plug is

installed on pins 11 and 12 on J3 of the EconoMi$er+ con-

troller. The pins are labeled ORH and VREF on the

EconoMi$er+ controller. See Fig. 22. The orange wire of the

harness is connected to pin 11 (ORH). The blue wire of the

harness is connected to pin 12 (VREF). The wiring harness

should be routed from the EconoMi$er+ controller to the sen-

sor location.

The outdoor enthalpy changeover curve is set at the

EconoMi$er+ controller. The factory default is curve “A.” See

Fig. 29. See Fig. 30 for Sensor Curve vs. Humidity.

L. Indoor Air Humidity Sensor

For differential enthalpy sensing, the EconoMi$er+ control-

ler uses the standard outdoor air temperature sensor, the

outdoor air humidity sensor, and the optional indoor air

humidity sensor, an optional return air temperature sensor

(RAT). The indoor-air humidity sensor is provided with a

2-wire, 42-in. wiring harness with a 2-pin connector. The

plug is installed on pins 8 and 9 on J3 of the EconoMi$er+

controller. The pins are labeled IRH and VREF on the

EconoMi$er+ controller. See Fig. 22. The orange wire of the

harness is connected to pin 8 (IRH). The blue wire of the har-

ness is connected to pin 9 (VREF). The wiring harness

should be extended with wires and wire nuts and routed

from the EconoMi$er+ controller to the sensor location. The

EconoMi$er+ controller compares the outdoor air enthalpy

to the return air enthalpy to determine EconoMi$er+ use.

The controller selects the lower enthalpy air (return or out-

door) for cooling. For example, when the outdoor air has a

lower enthalpy than the return air, the EconoMi$er+ control-

ler opens the damper to bring in outdoor air for free cooling.

Mount the return-air humidity sensor in the return-air duct.

See Fig. 31.

The outdoor enthalpy changeover curve is set with at the

EconoMi$er+ controller. The selectable curves are A, B, C,

and D. The factory default is curve “A.” See Fig. 29. See

Fig. 30 for Sensor Curve vs. Humidity.

M. Occupied/Unoccupied Switch

The EconoMi$er+ supports the use of a field-supplied occupied/

unoccupied switch. When the switch is closed it provides a

24-vac signal to the unit for occupied mode and when open,

there is no signal to indicate unoccupied mode. The control can

be configured to allow different minimum economizer damper

positions and to control how mechanical cooling will and will

not be used in the occupied mode.

NOTE: The remote potentiometer (see below) will override the

occupied minimum position if the potentiometer setting is

greater than the occupied minimum position.

For 3 to 121/2 ton units, a wire from J1-OCC (pin 4) and a

wire from J1-24V (pin 5) are wire-nutted together to jumper

the terminals.

An occupied/unoccupied switch can be field-installed in place

of the jumper to allow the user to force the control into occu-

pied or unoccupied mode of operation for EconoMi$er+

damper position. The occupied/unoccupied switch is required

if the user wants to use unoccupied free cooling or different

EconoMi$er+ damper vent positions in the unoccupied mode.

N. Power Exhaust

Refer to the Accessory Power Exhaust installation instructions

for information on installing the power exhaust accessory.

O. Remote EconoMi$er+ Enable Control

When the control is used with energy management systems that

enable and disable the EconoMi$er+, the user can install a field-

supplied enable/disable switch. The switch must be wired in

series with a 3K ohm, 1 watt or greater resistor. The switch is

wired to terminals ORH (pin 11) and VREF (pin 12) on J3. Refer

to the Start-Up section for details on how to configure the control.

P. R e mote Potentiometer Occupied MinimumPosition

The occupied minimum position set point remote potentiom-

eter (field-supplied) is used when requiring additional tem-

porary ventilation. The remote potentiometer (10K ohm -

closed damper, 100K ohm - open damper) will only control

the occupied minimum position.

The accessory 5-in wiring plug, CRE+PLUG001A00 is

required to connect the potentiometer.

The plug is installed on pins 15, 16 and 17 on J3 of the

EconoMi$er+ controller. The pins are labeled with the ground

symbol, MIN and VREF on the EconoMi$er+ controller. See

Fig. 22. The pink wire from the harness is connected to pin

15 (ground symbol). The gray wire from the harness is con-

nected to pin 16 (MIN). The yellow wire from the harness is

connected to pin 16 (VREF). The wiring harness should be

extended with wires and wire nuts and routed from the

EconoMi$er+ controller to the remote potentiometer location.

NOTE: Pins 13 (ground symbol) and 14 (IAQ), which are

wired to the accessory 5-pin plug, are not used for the remote

potentiometer installation. They are used for an accessory

IAQ sensor (if required).

The unoccupied minimum position can only be set at the con-

troller. The occupied minimum position set point configured

at the EconoMi$er+ controller should be set to 0 when using

a remote potentiometer. The occupied minimum position will

also be used as part of the IAQ routing; it will be the

maximum position the damper moves to when there is an

IAQ call.

If the remote potentiometer (occupied) position is greater

than the EconoMi$er+ controller unoccupied minimum posi-

tion, then the remote potentiometer setting will be used. The

remote potentiometer is field supplied and must be a 3-wire,

linear potentiometer with a resistance between 10K ohm

and 100K ohm (such as the Honeywell S963B1128).

Q.Demand Ventilation Control

Demand ventilation control uses an IAQ sensor

(CRE+PLUG001A00 required) to control the amount of out-

side air admitted into the system. Normally, the minimum

position of the EconoMi$er+ damper is established based on

the demand occupancy of the space. The IAQ sensor will be

used to modulate the EconoMi$er+ minimum damper posi-

tion below the normal minimum position based on full occu-

pancy. The lower limit is called the base ventilation rate. See

Fig. 32.

If there is no IAQ signal the damper will be in the unoccu-

pied minimum position (configuration item number 3). If

there is an IAQ signal the damper will be in the occupied

minimum position (configuration item number 15), unless

the remote potentiometer is used to override it.

For the demand ventilation control logic, the user configures

the lower and upper actuator position to establish the base

ventilation rate (IAQMIN_SP) and the design ventilation rate

(ECONOMIN_SP) for full occupancy. When the EconoMi$er+

damper is being modulated for demand ventilation control,

the damper position will be between IAQMIN_SP and

ECONOMIN_SP. The upper IAQ differential set point is

DAQHI. The lower IAQ differential set point is DAQLO.

The differential set points represent the differential CO2

level (in ppm) above the outdoor reference IAQ levels. Nor-

mally, the outdoor reference IAQ levels are around 400 ppm,

but the value should be configured based on the reference

levels taken at the job site.

The following equation is used to determine EconoMi$er+

damper position (ECONOMIN_POS):

R. CO2Sensor Configuration

The CO2 sensor has preset standard voltage settings that

can be selected anytime after the sensor is powered up. See

Table 7.

1. Press Clear and Mode buttons. Hold at least 5 seconds

until the sensor enters the Edit mode.

2. Press Mode 2 times. The STDSET Menu will appear.

3. Use the Up/Down button to select the preset number.

See Table 7.

4. Press Enter to lock in the selection.

Press Mode to exit and resume normal operation. The cus-

tom settings of the CO2 sensor can be changed any time after

the sensor is energized. Follow the steps below to change the

non-standard settings:

1. Press Clear and Mode buttons. Hold at least 5 sec-

onds until the sensor enters the Edit mode.

2. Press Mode twice. The STDSET Menu will appear.

3. Use the Up/Down button to toggle to the NONSTD

menu and press Enter.

4. Use the Up/Down button to toggle through each of

the nine variables, starting with Altitude, until the

desired setting is reached.

5. Press Mode to move through the variables.

6. Press Enter to lock in the selection, then press Mode

to continue to the next variable.

S. Dehumidification of FreshAir withDemand Control

Ventilation (DCV)

Information from ASHRAE (American Society of Heating,

Refrigeration and Air Conditioning Engineers) indicates that

the largest humidity load on any zone is the fresh air intro-

duced. For some applications, a device such as a energy

recovery unit is added to reduce the moisture content of the

fresh air being brought into the building when the enthalpy

is high. In most cases, the normal heating and cooling pro-

cesses are more than adequate to remove the humidity loads

for most commercial applications.

This makes the control of the dehumidification device simple

when using the enthalpy or differential enthalpy sensor. The

enthalpy sensor or differential enthalpy sensor is installed

on the equipment to determine economizer operation. The

high enthalpy signal from the temperature and humidity

sensors or differential temperature and humidity sensors

can be used to turn on the outdoor air moisture removal

device any time fresh air is required for the space.

The energy recovery device should be sized for maximum

latent and sensible conditioning at maximum ventilation on

a design day.

A calculation for leaving-air temperature on a low ambient,

low ventilation day should also be done to determine the

supply-air temperature of the return and pre-conditioned

outside air. The design should produce air temperature

somewhat near room conditions to prevent reheat of the air

mixture. The energy recovery device should be interlocked

with the heat to turn off the device when in the heat mode.

PRE-START-UP

Proceed as follows to inspect and prepare the unit for initial

start-up:

1. Remove all access panels.

2. Read and follow instructions on all WARNING, CAU-

TION, and INFORMATION labels attached to, or

shipped with, unit.

3. Make the following inspections:

a. Inspect for shipping and handling damages such

as broken lines, loose parts, or disconnected

wires, etc.

b. Inspect for oil at all refrigerant tubing connec-

tions and on unit base. Detecting oil generally

indicates a refrigerant leak. Leak-test all refrig-

erant tubing connections using electronic leak

detector, halide torch, or liquid-soap solution.

c. Inspect all field-wiring and factory-wiring con-

nections. Be sure that connections are completed

and tight. Be sure that wires are not in contact

with refrigerant tubing or sharp edges.

d. Inspect coil fins. If damaged during shipping and

handling, carefully straighten fins with a fin

comb.

4. Verify the following conditions:

a. Make sure that condenser-fan blade are correctly

positioned in fan orifice. See Condenser-Fan

Adjustment section on page 62 for more details.

b. Make sure that air filter(s) is in place.

c. Make sure that condensate drain trap is filled

with water to ensure proper drainage.

d. Make sure that all tools and miscellaneous loose

parts have been removed.

START-UP

I. UNIT PREPARATION

Make sure that unit has been installed in accordance with

these installation instructions and applicable codes. Make

sure that Start-Up Checklist, located on back page of this

booklet, has been completed and filled out.

II. RETURN-AIR FILTERS

Make sure correct filters are installed in filter tracks (see Tables

1A and 1B). Do not operate unit without return-air filters.

III. OUTDOOR-AIR INLET SCREENS

Outdoor-air inlet screens must be in place before operating

unit.

IV. COMPRESSOR MOUNTING

Compressors are internally spring mounted. Do not loosen or

remove compressor holddown bolts. On 580F150 and 151

units, remove the tiedown bands that hold the compressors

together.

V. INTERNAL WIRING

Check all electrical connections in unit control boxes.

Tighten as required. Ensure wiring does not come into direct

contact with refrigerant tubing.

VI. GAS PIPING

Check gas piping for leaks.

VII. REFRIGERANT SERVICE PORTS

To service refrigerant service ports, remove compressor

access panel. Each unit system has 3 Schrader-type service

gage ports: one on the suction line, one on the liquid line, and

one on the compressor discharge line. Be sure that caps on

the ports are tight. The Schrader-type valve on the discharge

line is located under the low-pressure switch. Another valve

is located on the discharge line underneath the high-

pressure switch. It is screwed on a Schrader fitting but there

is no Schrader core.

VIII. HIGH FLOW VALVES

Located on the compressor hot gas and suction tubes are

High Flow Valves. Large black plastic caps distinguish these

valves with O-rings located inside the caps. These valves can

not be accessed for service in the field. Ensure the plastic

caps are in place and tight or the possibility of refrigerant

leakage could occur.

IX. COMPRESSOR ROTATION

On 3-phase units with scroll compressors, it is important to

be certain compressor is rotating in the proper direction. To

determine whether or not compressor is rotating in the

proper direction:

1. Connect service gages to suction and discharge pres-

sure fittings.

2. Energize the compressor.

3. The suction pressure should drop and the discharge

pressure should rise, as is normal on any start-up.

WARNING: Failure to observe the following warn-

ings could result in serious personal injury.

1. Follow recognized safety practices and wear

protective goggles when checking or servicing

refrigerant system.

2. Do not operate compressor or provide any elec-

tric power to unit unless compressor terminal

cover is in place and secured.

3. Do not remove compressor terminal cover until

all electrical sources are disconnected.

4. Relieve all pressure from system before touch-

ing or disturbing anything inside terminal box

if refrigerant leak is suspected around compres-

sor terminals.

5. Never attempt to repair soldered connection

while refrigerant system is under pressure.

6. Do not use torch to remove any component. Sys-

tem contains oil and refrigerant under pres-

sure. To remove a component, wear protective

goggles and proceed as follows:

a. Shut off electrical power and then gas to

unit.

b. Reclaim refrigerant to relieve all pressure

from system using both high- and low-pres-

sure ports.

c. Cut component connection tubing with tub-

ing cutter and remove component from

unit.

d. Carefully unsweat remaining tubing stubs

when necessary. Oil can ignite when

exposed to torch flame.

WARNING: Disconnect gas piping from unit when

leak testing at pressure greater than 1/2 psig. Pres-

sures greater than 1/2 psig will cause gas valve damage

resulting in hazardous condition. If gas valve is sub-

jected to pressure greater than 1/2 psig, it must be

replaced before use. When pressure testing field-

supplied gas piping at pressures of 1/2 psig or less, a

unit connected to such piping must be isolated by man-

ually closing the gas valve.

—51—

If the suction pressure does not drop and the discharge pres-

sure does not rise to normal levels:

1. Note that the evaporator fan is probably also rotating

in the wrong direction.

2. Turn off power to the unit and install lockout tag.

3. Reverse any two of the unit power leads.

4. Reapply power to unit. Reenergize compressor.

The suction and discharge pressure levels should now move

to their normal start-up levels.

NOTE: When the compressor is rotating in the wrong direc-

tion, the unit will make an elevated level of noise and will

not provide cooling.

X. COOLING

To start unit, turn on main power supply. Set system selector

switch at COOL position and fan switch at AUTO. position.

Adjust thermostat to a setting below room temperature.

Compressor, indoor and outdoor fans start on closure of

contactors.

Check unit charge. Refer to Checking and Adjusting

Refrigerant Charge section, page 62. Unit must operate a

minimum of 10 minutes before adjusting charge.

Reset thermostat at a position above room temperature.

Compressor and outdoor fans will shut off. Evaporator fan

will shut off after 30-second delay.

A. To Shut Off Unit

Set system selector switch at OFF position. Resetting ther-

mostat at a position above room temperature shuts unit off

temporarily until space temperature exceeds thermostat

setting.

XI. MAIN BURNERS

Main burners are factory set and should require no

adjustment.

TO CHECK ignition of main burners and heating controls,

move thermostat set point above room temperature and ver-

ify that the burners light and evaporator fan is energized.

After ensuring that the unit continues to heat the building,

lower the thermostat setting below the room temperature

and verify that the burners and evaporator fan turn off (fan

will turn off only if fan selector switch is in the AUTO. posi-

tion). Refer to Table 31 for the correct orifice to use at high

altitudes.

NOTE: Upon a call for heat, the main burners will remain on

for a minimum of 60 seconds.

A. Adjust Gas Input

The gas input to the unit is determined by measuring the

gas flow at the meter or by measuring the manifold pressure.

Manifold pressure should be 3.5 in. wg. in high-fire

operation.

NOTE: Unit uses a 2-stage gas valve. There is no need to

adjust the “Low Fire” manifold pressure.

Measure Gas Flow (Natural Gas Units)

Minor adjustment to the gas flow can be made by changing

the manifold pressure. The manifold pressure must be

3.5 in. wg. Normal manifold pressure is 3.5 in. wg in high

fire (W1 and W2 inputs to gas valve).

Proceed as follows:

1. Turn off gas supply to unit.

2. Remove pipe plug on manifold then connect manome-

ter at this point. Turn on gas to unit. Ensure gas

valve is in high fire operation.

Observe manifold pressure in high fire (W1 and W2 ener-

gized) and proceed as follows to adjust gas input:

1. Remove cover screw over regulator adjustment screw

on gas valve. Ensure gas valve is operating in high

fire mode.

2. Turn regulator adjustment screw clockwise to

increase gas input, or turn regulator adjustment

screw counterclockwise to decrease input. High fire

manifold pressure must be 3.5 in. wg.

3. Replace cover screw cap on gas valve.

4. Turn off gas supply to unit. Remove manometer from

pressure tap and replace pipe plug on gas valve. Turn

on gas to unit and check for leaks.

Table 31 — Altitude Compensation*

*As the height above sea level increases, there is less oxygen per cubic foot

of air. Therefore, heat input rate should be reduced at higher altitudes.

†Orifice available through your local distributor.

XII. HEATING

1. Purge gas supply line of air by opening union ahead

of gas valve. When gas odor is detected, tighten union

and wait 5 minutes before proceeding.

2. Turn on electrical supply and open manual gas valve.

3. Set system switch selector at HEAT position and fan

switch at AUTO. or ON position. Set heating temper-

ature lever above room temperature.

4. The induced-draft motor will start, purging heat

exchangers.

5. After a call for heating, the main burners should light

within 5 seconds. If the burners do not light, then

there is a 22-second delay before another 5-second

ignition try. If the burners still do not light, the time

delay is repeated. If the burners do not light within

15 minutes, there is a lockout. To reset the control,

break the 24 v power to W1.

6. The evaporator-fan motor will turn on 45 seconds

after the burners are ignited.

7. The evaporator-fan motor will turn off 45 seconds

after the thermostat temperature is satisfied.

8. Adjust airflow to obtain a temperature rise within

the range specified on the unit nameplate and in

Tables 1A and 1B.

WARNING: Unsafe operation of the unit may

result if manifold pressure is outside 3.4 to 3.6 in. wg

range. Personal injury or unit damage may result.

XIII. INTEGRATED GAS CONTROLLER (IGC)OPERATION

NOTE: The default value for the evaporator-fan motor ON

and OFF delay is 45 seconds. The Integrated Gas Controller

(IGC) modifies this value when abnormal limit switch cycles

occur. Based upon unit operating conditions, the ON delay

can be reduced to 0 seconds and the OFF delay can be

extended to 180 seconds.

When one flash of the LED (light-emitting diode) is

observed, the evaporator-fan ON/OFF delay has been modi-

fied. If the limit switch trips at the start of the heating cycle

during the evaporator ON delay, the time period of the ON

delay for the next cycle will be 5 seconds less than the time

at which the switch tripped. (Example: If the limit switch

trips at 30 seconds, the evaporator-fan ON delay for the next

cycle will occur at 25 seconds.) To prevent short-cycling, a

5-second reduction will only occur if a minimum of 10 min-

utes has elapsed since the last call for heating.

The evaporator-fan OFF delay can also be modified. Once the

call for heating has ended, there is a 10-minute period dur-

ing which the modification can occur. If the limit switch trips

during this period, the evaporator-fan OFF delay will

increase by 15 seconds on the next cycle. A maximum of 9

trips can occur, extending the evaporator-fan OFF delay to

180 seconds. To restore the original default value, reset the

power to the unit.

A. To Shut Off Unit

Set system selector switch at OFF position. Resetting heat-

ing selector lever below room temperature will shut unit off

temporarily until space temperature falls below thermostat

setting.

XIV. SAFETY RELIEF

A soft-solder joint at the suction line Schrader port provides

pressure relief under abnormal temperature and pressure

conditions.

XV. VENTILATION (Continuous Fan)

Set fan and system selector switches at ON and OFF posi-

tions, respectively. Evaporator fan operates continuously to

provide constant air circulation. When the evaporator-fan

selector switch is turned to the OFF position, there is a

30-second delay before the fan turns off.

XVI. ECONOMI$ER+ CONTROLLER

The EconoMi$er+ controller is mounted to the top of the

EconoMi$er+ damper and is accessible by removing the filter

access door of the unit.

The EconoMi$er+ controller is protected by a sheet metal

enclosure mounted over the controller. Remove the single

screw on the front of the enclosure and lift off the top for

access to the controller. The primary purpose of the control-

ler is to provide control of the EconoMi$er+ dampers and the

cooling compression stages. The status of the indoor fan is

monitored through the G input but is not directly controlled

by the controller. The heating function is completely inde-

pendent of the controller.

IMPORTANT: The controller can only be used with conven-

tional thermostats with Y1, Y2 and G input to the controller;

it can NOT be used with electronic thermostats with a pro-

portional room temperature input, or with Variable Air Vol-

ume systems.

There are 4 LEDs on the controller, which are used to read val-

ues and display status and configuration information. There

are 2 buttons (READ/ADJUST and ADVANCE/MANUAL),

which change modes and configure the controller. See Fig. 36.

The EconoMi$er+ microprocessor based control system pro-

vides the following control functions:

• EconoMi$er+ damper control for free cooling

• Minimum position control for ventilation

• Demand Ventilation Control using a CO2 sensor

• Compressor Cooling Stage Control

• Occupied/Unoccupied Control

• Diagnostics Display and History

• Manual test control

See Table 32 for Inputs and Outputs.

A. Integrated Display

The control board includes an integrated display, which is

used for the following functions:

• Configuration and setup

• Set point and control adjustment

• Error status and alarm monitoring

• Manual control

• Reading sensor values

There are 5 modes of display operation:

•Startup Mode

•Run Mode

• Read Mode

•Setup Mode

• Manual Mode

External devices are not required to operate and configure

the control.

B. Startup Mode

During the first 3 seconds after power is applied to the con-

trol, the four LEDs flash as shown in Table 33, indicating

that the control is being initialized. The buttons are not

operational during Startup mode.

C. Run Mode

Run mode indicates status of controller and unit. The mode

can be changed to the Read, Setup, or Manual modes by

pushing various buttons.

While the control is in Run mode, the DS1 heartbeat indica-

tor LED (red) will flash to indicate the controller is operating

properly. The DS2 Econo indicator LED (yellow) will flash

whenever economizer is being used for free cooling. The DS3

first stage cooling indicator LED (green) will be on steady

indicate demand for stage 1 cooling. The DS4 second stage

cooling indicator LED (green) will be on steady to indicate

demand for stage 2 cooling.

If the controller is in a different mode, the controller will

return to Run mode after 10 minutes of user inactivity or if

the READ/ADJUST (#1) and ADVANCE/MANUAL (#2) but-

tons are held for at least 3 seconds until all LEDs flash.

D. Read Mode

Read mode is used to check set points (Table 34) and I/O

channel status (Table 35). Enter the Read mode by pushing

and releasing the READ/ADJUST (#1) button. A user can

only enter Read mode from the Run mode (to get to Run

mode, press both the #1 and #2 buttons for at least 3 seconds

until all LEDs flash). In Read mode, LEDs are not lit until

the READ/ADJUST button (#1) is pushed.

NOTE: If the user pushes and holds the READ/ADJUST but-

ton (#1) for more than 3 seconds, then the control will go into

the Setup mode, indicated by the yellow LED (on steady).

While in Read mode, push button #1 then the DS1 LED

(Red) flashes to indicate setup point number as defined in

the setup table. The two green LEDs will then show the

value of the display item. The DS3 LED will first display the

—53—

tens digit and the DS4 LED will then display the ones digit.

For example to display 54, the DS3 LED will flash 1 group of

5 at a high flash rate to indicate 50, and then follow with 4

flashes (DS4) at 1-second intervals to complete the display of

the number 54.

NOTE: Do not try to count the “5 Fast Flashes” individually,

but instead count how many groups of 5 flashes were

displayed. In this case, 1 group of 5 flashes, plus the 4 flashes

at 1 second results in the value of 54.

To read the display again, push the READ/ADJUST (#1) but-

ton and the sequence will repeat as many times as needed.

To advance to the next setup point, push the ADVANCE/

MANUAL (#2) button. The controller will cycle through all

the setup channels (Table 34) and then the I/O channels

(Table 35) and then back to the first setup channel.

NOTE: The user can only advance forward, not reset to #1 or go

backwards. Cycling the EconoMi$er+ power will reset the item

number (but not the item value) to item #1.

In the Read mode for setup variables, the LEDs will not turn

on steady; the LEDs will always flash. Steady-on indicators

are reserved for the configuration modes. No data is modified

in the Read mode. The controller will always remain at the

last read number even if reset back to normal operation.

NOTE: To enter another mode, the user first must exit the

Read mode.

If no button is pushed in 10 minutes, Read mode will auto-

matically be exited. Also, if the READ/ADJUST (#1) and

ADVANCE/MANUAL (#2) buttons are pushed and held for

more than 3 seconds, then Read mode will be exited to Run

mode. While in the Read mode, the controller will continue to

operate with normal unit control.

After advancing through all the configuration variables in

the Read mode, the controller will then advance through the

status of the I/O channels. As in the Read mode, there will be

no LEDs on. Push the READ/ADJUST (#1) button and the

yellow LED will flash the “I/O Point” number and the green

LEDs will flash the “I/O Values” in the same manner

described in the Read mode section. See Table 35. At the first

I/O point (Compressor 1 Output), the DS2 LED (Yellow) will

flash with the number of the I/O channel and the DS1 LED

(red) will stop flashing. This will be followed by the I/O chan-

nel status. To read the value again, push the READ/ADJUST

(#1) button.

To advance to the next channel, push the ADVANCE/

MANUAL (#2) button. If the number of the channel or the

status value is greater than 4 the controller will count out

the increments of 5 at a high flash rate followed by the

remaining digits. The channel number will be counted out

through the DS2 LED (yellow). The status value will be

counted out through the DS3 and DS4 LEDs (green).

If the status value is an analog value then the numeric value

will be displayed by using the DS3 Green LED to display the

tens digit and the DS4 will be used to display the ones digit.

If the channel is a digital output (relay), the DS3 LED (flash-

ing green) will indicate ON status and the DS4 LED (flash-

ing green) will indicate OFF status. If the output is the

economizer control signal then the DS3 LED will be used to

indicate the motor is being driven open, and the DS4 LED

will be used to indicate it is being closed. If the motor is not

being commanded in either direction then both the DS3 and

DS4 LEDs will be on. The controller will first go through the

output relays, then the economizer motor, and will then fol-

low with the values currently being read for the analog input

channels as defined in the configuration table. All values are

maintained in memory even during a power loss. To exit

Setup mode, push and hold the READ/ADJUST (#1) and

ADVANCE/MANUAL (#2) buttons for more than 3 seconds.

Setup mode will automatically be exited after 10 minutes of

no activity.

E. Setup Mode

The Setup mode is used to change set points and configura-

tion values.

Enter the Setup mode by pushing and holding the READ/

ADJUST (#1) button 1 for at least 3 seconds until all LEDs

flash once. Then, the yellow LED will come on steady. A user

can only enter the Setup mode from the Run mode (to get to

Run mode, press buttons both buttons #1 and #2 for at least

3 seconds).

In Setup mode, all configurations can be modified even while

the unit is running, but the user will not be able to adjust the

I/O channels. Only channels 1 through 20 on Table 34 will be

accessible in the Setup mode. Channel 20 will be used to

reset any alarms that may have occurred. As an option,

alarms can also be reset by cycling power to the controller.

NOTE: During the Setup mode, all routines including safety

routines will continue to run and control the unit.

While in this mode, the DS1 LED (red) will flash to indicate

the number of the configuration item. The DS2 LED (yellow)

will be on continuously to indicate that the unit is in configu-

ration mode. Use the ADVANCE/MANUAL button to

sequence through the setup channels. If the value of the

channel is less than 5 it will count out the value of the chan-

nel on the DS1 LED at 1-second intervals. If the channel

value is 5 or greater, the DS1 LED will first count out the

groups of 5 and then following with the remaining digit.

Verify what Setup Point is being read by pushing the READ/

ADJUST button (#1). First the Red LED will flash the set

point number, then the Green LEDs will flash the value.

Then, the green DS3 and DS4 LEDs will each come on

steady for about 2 seconds. While DS3 is on steady, its new

value can be entered by pushing READ/ADJUST (#1), and

entering the value for the ten’s digit. When the DS4 comes

on steady, enter the value for the one's digit. After the green

LEDs are off, push the READ/ADJUST button (#1) again to

verify that the correct value has been entered. If the configu-

ration is a discrete On/off setting, push the READ/ADJUST

button (#1) to toggle LED 3 or 4 on or off.

Setup Example 1: Change “Occupied Minimum Position”

(configuration item 2) to 53%.

1. Read the General Notes about reading and entering

values found on the label on the top of the

EconoMi$er+.

2. Push and hold button #1 (READ/ADJUST) for at

least 3 seconds until all LEDs flash. The yellow LED

will go on steady.

3. Read the current configuration point by pushing but-

ton #1. The red LED flashes the configuration point

number and the green LEDs flash the current setting

for that setup point number.

4. On the label (on top of the EconoMi$er+), read Step 2

and Note 1 for Setup mode operation.

5. Use button #2 (ADVANCE/MANUAL) to advance to

configuration point number 2, Occupied Min.

NOTE: Before performing Step 6, be ready to push button #1;

there is a limited time window that can easily be missed when

the DS3 green LED comes on, and again when the DS4 green

LED comes on.

6. Verify the configuration point by pushing button #1.

The red LED should flash twice to indicate point 2,

and then the green LEDs will flash the current set-

ting.

7. Next, the green DS3 LED will turn on steady for 2

seconds. During this time, push button #1 five times.

8. The DS3 LED will turn off and the green DS4 LED

will go on steady for 2 seconds. During this time,

push button #1 three times.

9. The 5 button #1 pushes, followed by the 3 button #1

pushes is the sequence that sets the occupied mini-

mum position to 53%.

10. Wait until the green LEDs turn off then verify the

setting by pushing button #1 to read the value. There

should be 5 fast blinks of DS3 and 3 slow blinks of

DS4.

Setup Example 2: Change the Occupied Minimum Position

(item 2) to 2% (lowest value).

1. Read the General Notes about reading and entering

values found on the label on the top of the

EconoMi$er+.

2. Push and hold button #1 (READ/ADJUST) for at

least 3 seconds until all LEDs flash. The yellow LED

will go on steady.

3. Read the current configuration point by pushing but-

ton #1. The red LED flashes the configuration point

number and the green LEDs flash the current setting

for that setup point number.

4. On the label (on top of the EconoMi$er+), read Step 2

and Note 1 for Setup mode operation.

—57—

5. Use button #2 (ADVANCE/MANUAL) to advance to

configuration point number 2, Occupied Min.

6. Verify the configuration point by pushing button #1.

The red LED should flash twice to indicate point 2,

and then the green LEDs will flash the current setting.

NOTE: Since the occupied minimum position MUST be 1

greater than the IAQ minimum position (item 15), the IAQ

minimum position must be changed first. (IAQ min has a

default value of 5%, which is higher than the 2% value in this

example.)

7. Use button #2 (ADVANCE/MANUAL) to get to config-

uration point 15 (IAQ Minimum Position).

NOTE: Before performing Step 8, be ready to push button #1;

there is a limited time window that can easily be missed when

the DS3 green LED comes on, and again when the DS4 green

LED comes on.

8. Verify the configuration point by pushing button #1.

The red LED should flash 15 times to indicate point

15, then the green LEDs will flash the current

setting.

9. Next, the green DS3 LED will turn on steady for

2 seconds. During this time, do NOT do anything so

that the position defaults to 0.

10. The DS3 LED will turn off and the green DS4 LED

will go on steady for 2 seconds. During this time,

push button #1 once to set the point to 1%.

11. Wait until the green LEDs turn off then verify the

setting by pushing button #1 to read the value. DS3

should not blink, and DS4 should blink once.

12. Now configure the Occupied Minimum Position to

2%. Use button #2 (ADVANCE/MANUAL) to get to

configuration point 2.

NOTE: Before performing Step 13, be ready to push button #1;

there is a limited time window that can easily be missed when

the DS3 green LED comes on, and again when the DS4 green

LED comes on.

13. Verify the configuration point by pushing button #1.

The red LED should flash twice to indicate point 2,

then the green LEDs will flash the current setting.

14. Next, the green DS3 LED will turn on steady for

2 seconds. During this time, do NOT do anything so

that the position goes to 0.

15. The DS3 LED will turn off and the green DS4 LED

will go on steady for 2 seconds. During this time,

push button #1 twice to set the point to 2%.

16. Wait until the green LEDs turn off then verify the

setting by pushing button #1 to read the value. DS3

should not blink, and DS4 should blink twice.

NOTE: Configuration items 2, 15, 11, 12, 18 and 19 (in

Table 34) are dependent upon other items. Before attempting

to change one of these items, be sure to check the value of the

item it depends upon (as described in Example 2 above).

IMPORTANT: During SETUP MODE, changes are allowed

when the DS3 LED and DS4 LED are lit for 2 seconds (as

described in Example 1 and 2 above). During this time, if

button #1 is pushed to change one position and not the other,

the value for that one position will change and the other will

default to zero (unless a dependency prevents the zero). How-

ever, if button #1 is not pushed at all during the 2 seconds

that the green LEDs are lit, the configuration item will not

change.

F. Manual Mode

Manual mode is used to control the status of I/O channels for

use in troubleshooting. See Table 35.

Enter the Manual mode by holding down the ADVANCE/

MANUAL (#2) button for at least 3 seconds until all LEDs

flash and then the red LED comes on steady.

NOTE: A user can only enter the Manual mode from the Run

mode, which is entered by pushing buttons #1 and #2 for at

least 3 seconds.

All EconoMi$er+ control outputs are turned off. “I/O Inputs”

1-5 can be adjusted even if the unit is in operation.

In manual mode, the yellow DS2 LED flashes once to indicate

the I/O channel. See Table 35. If the value is less than 5, the

yellow DS2 LED will count out the value using 1-second

flashes. If the value is greater than 4, the yellow DS2 LED

will count out groups of 5 at a high flash rate and then follow

with the additional value at a flash rate of once per second.

For example a flash of 1 indicates Compressor Relay Output 1.

Push READ/ADJUST button (#1) to read the value. The yel-

low LED will flash the I/O Channel number being viewed.

Once the channel number is displayed it will then turn on

the appropriate green LED (DS3 or DS4) to indicate the sta-

tus of the output. For relay outputs if the DS3 LED is on,

then the output is on. If DS4 is on, then the output is off. The

green DS3 and DS4 LEDs will remain on for about 2 seconds

and if during this time the READ/ADJUST (#1) button is

pushed, then the output will toggle to the alternate state. To

change again, push the READ/ADJUST button and repeat

the test or change the status of the output. As an example,

for channel 5 (EconoMi$er+ control damper motor) use the

READ/ADJUST button to toggle the motor from open to

close in %.

At any time, the ADVANCE/MANUAL (#2) button can be

used to advance to the next SET I/O. To exit the mode, push

and hold the READ/ADJUST and ADVANCE/MANUAL but-

tons (#1 and #2) for more than 3 seconds.

NOTE: After exiting the Manual mode, the controller will re-

initialize and start with all outputs off.

G. Error Mode

The error mode is used to indicate that an error has occurred

The error is indicated by LED #1 red and #2 yellow are on

steady.

Enter the RUN mode by pushing the READ/ADJUST and

ADVANCE/MANUAL buttons (#1 and #2) for at least 3 sec-

onds until all LEDs flash. Next, push and release button #1

to enter the Read mode. Then push button #2 to advance to

item 20 (“first most recent error”). Determine the error by

reading the value in items 20 to 24 and referring to the Trou-

bleshooting section.

Once the error has been fixed, press buttons #1 and 2 for at

least 3 seconds to exit Read mode. All LEDs will flash.

Enter Setup mode by pressing the READ/ADJUST button

(#1) for at least 3 seconds. All LEDs will flash. Push the

ADVANCE/MANUAL button (#2) to advance to item 20.

Push READ/ADJUST to read item 20.

To reset the error code while the green DS4 LED is on, press

the READ/ADJUST button (#1) once. In addition to resetting

the error mode, this will erase all error codes. Cycling the

power will also erase the error code.

XVII. ECONOMI$ER+ CONFIGURATION

For most applications, the factory setting will be used to con-

trol the EconoMi$er+. However, there are 19 different vari-

ables that can be used to configure the control for wide range

of applications. The factory settings and variables are shown

in Table 34.

IMPORTANT: There is no way to reset/restore the factory

default configurations; use caution when making changes to

any set point or operational variable.

The EconoMi$er+ control accepts an occupied/unoccupied

switch input. This input is used to control the occupied and

unoccupied minimum ventilation damper position as shown in

Table 34 items 2 (ECONOMIN_SP) and 3 (U_ECONOMIN_SP).

These values represent the minimum damper position. In addi-

tion, the controls allows for different modes of compressor opera-

tion in the unoccupied mode. Using item 13 in Table 34

(OCC_MODE), the user can select one of the following unoccu-

pied modes:

• No unoccupied cooling

• Unoccupied free cooling (EconoMi$er+)

• Unoccupied free cooling and mechanical cooling

The EconoMi$er+ will control the cooling operation of the

unit based on the demand from the thermostat outputs Y1

and Y2. The EconoMi$er+ will monitor the fan output G, but

will not control the fan directly. Note that G must be ener-

gized for any cooling to take place. Gas or electric heating

will be controlled directly from the thermostat.

When a demand for cooling occurs, the control will check to

see if it is in the occupied or unoccupied mode. Depending on

the configuration, the control will move the outdoor air

damper to the ventilation position. If the outdoor air condi-

tions are acceptable, then the control will use the

EconoMi$er+ for free cooling. If the supply-air temperature

does not meet the configurable set point, then the control

will turn on additional stages of mechanical cooling. Several

compressor sequences can be used depending on the applica-

tion requirements; these will be covered in the mechanical

compressor staging section.

A. Compressor Configuration And Control

The EconoMi$er+ control can support from 1 to 4 compres-

sor stages. For the 3 to 121/2 ton units, there will only be 1 or

2 stages of compressor cooling, so the control is factory

configured for 2 stages. There is no difference between 1 and

2 stages. The control also provides the option to configure for

high sensible or high latent loads, but for units with only two

compressors this option does not apply.

Compressors are configured using item 10 (STAGE_TYPE)

in Table 34. The control also has the capability of controlling

directly to Y1 and Y2 inputs. The control can be configured

to control to the leaving-air temperature using Y1 and Y2 as

a low cool and high cool demand based on the supply air set

point and the rate of change of supply-air temperature. For

low cool the leaving air temperature set point will be

SAT_SP +2° F. For high cool the leaving air temperature set

point will be the supply-air temperature set point (SAT_SP).

To use this option, configure the compressor sequencing vari-

able (STAGE_TYPE) to a value of 3. Configure the supply air

temperature set point (SAT_SP) to the desired leaving air

temperature.

NOTE: The supply air temperature set point is also the tem-

perature used for EconoMi$er+ control.

The logic will control the operation of the compressors

depending on the configuration selected. If free cooling can

be used, then the compressors will be integrated with the

EconoMi$er+ to provide the lowest cost cooling control. The

logic includes time guards on the compressors to provide a

minimum of 3 minutes on and 3 minutes off time. The con-

trol will also prevent two compressors from starting at the

same time. The logic uses the EconoMi$er+ to prevent rapid

cycling of the compressors and low air temperatures.

B. Ventilation Air And Free Cooling

In order for the EconoMi$er+ to control ventilation air and

free cooling, several items must be configured.

EconoMi$er+ Type

First, select the EconoMi$er+ control type that will be used.

This is the EconoMi$er+ Type function (ECONO_TYPE)

defined by item 5 in Table 34. The choices are:

1. Vent only — This is used to have just ventilation con-

trol. The EconoMi$er+ will not provide free cooling,

but the occupied and unoccupied minimum positions

can be used.

2. Proportional — In this configuration, full propor-

tional EconoMi$er+ control will be used. When

EconoMi$er+ free cooling cannot be used, the damp-

ers will be set to the appropriate occupied and unoc-

cupied minimum positions.

3. Three-Position — This mode of EconoMi$er+ is used

to provide a minimum ventilation EconoMi$er+ posi-

tion and a fixed free cooling or high ventilation posi-

tion. The high ventilation position is controlled by the

optional Remote EconoMi$er+ Enable Switch Input

connected to terminals 11 and 12 on T3.

Supply Air Temperature Set Point

Once the type of EconoMi$er+ control has been selected, the

user will need to set the Supply Air Temperature set point

(SAT_SP). The SAT_SP has a range of 40 to 65 F.

NOTE: This will be the set point when both Y1 and Y2 are

closed. When just Y1 is closed, the set point will be ° F higher.

Minimum Damper Position

Set the occupied minimum damper position (ECONOMIN_SP)

and unoccupied minimum position (U_ECONOMIN_SP).

These should be set to provide the ventilation requirements at

full occupancy as defined by the building specifications. When

demand ventilation is used, the control will close the dampers

below this position based on measured CO2 levels in the space

to provide additional operation savings.

The control will also allow for the use of a remote minimum

position potentiometer. This will only adjust the Occupied

Minimum position. If used, the software set point

ECONOMIN_SP should be set to 0 as the control will use the

largest set point.

The damper position is not linear with the amount of outside

air, so the user will need to set the position of the

EconoMi$er+ accordingly. It is best to use the following equa-

tion and measured data to set the position:

OA = % outdoor air

SAT = supply air temperature

RAT = return air temperature

OAT = outdoor air temperature

The SAT and OAT values can be read from the control and, if

the unit is equipped with an RAT sensor, then all three

values can be read. For the calculation to work properly,

there should be at least a 10° F difference between the OAT

and RAT temperatures.

OA = SAT – RAT *100

OAT – RAT

—59—

Maximum Damper Position

Set the maximum EconoMi$er+ position. Normally this is

set at 100%. If using 3-position control or there is a reason

not to use 100% outside air, this can be set using the

EconoMi$er+ Maximum Position (MAX_POS_SP).

Compressor Lockout Temperature

Set the Compressor Lockout Temperature. The Compressor

Lockout Temperature (CMP_LOCK) is used to prevent com-

pressor from running at low ambient conditions when an

EconoMi$er+ can easily satisfy the load.

EconoMi$er+ Changeover Control

Determine the type of EconoMi$er+ changeover control

which will be used to enable and disable free cooling. This is

done using the EconoMi$er+ Changeover Type.

1. Switch — This changeover setting is used when a

remote signal from an energy management system

will enable and disable the EconoMi$er+. This is

done through a remote EconoMi$er+ enable switch.

2. Outdoor Dry Bulb — For this changeover setting, the

EconoMi$er+ will be enabled based on the outdoor-air

temperature. The EconoMi$er+ is shipped with an

outdoor air temperature sensor. The outdoor air tem-

perature set point can be configured by the user. The

EconoMi$er+ will be disabled when the outdoor-air

temperature rises above the set point. The configura-

tion variable is the EconoMi$er+ Changeover set

point (OAT_SP).

3. Differential Dry Bulb — For this changeover setting,

the EconoMi$er+ will be enabled whenever the out-

side-air temperature is lower than the return-air

temperature. No configuration of set points is

required other than to select the differential dry bulb

function.

4. Outdoor Enthalpy — For this changeover setting, the

control will enable the EconoMi$er+ based on the

outdoor-air enthalpy curves as shown in Fig. 29.

Using the EconoMi$er+ Changeover set point

(ENTHALPY_SP), select curves A, B, C or D. The

control will then use the EconoMi$er+ at conditions

below the curve. The control uses the OAT and

optional humidity sensor to calculate the enthalpy

and also has the A, B, C, and D curves stored in

memory.

5. Differential Enthalpy — For this changeover setting,

the EconoMi$er+ will be enabled based on the com-

parison of the enthalpy of the return air and outside

air. If the outside air enthalpy is lower than the

return air, then the EconoMi$er+ will be enabled. To

use this option, an accessory outside air humidity

sensor, a return air dry bulb sensor and a return air

humidity sensor must be ordered and installed. No

configuration of set points is required other than to

select the function.

C. Demand Ventilation Configuration

The EconoMi$er+ control has demand ventilation control

capability when using an IAQ sensor. The indoor air quality

(IAQ) is measured using a CO2 sensor. The IAQ sensor can

be field-installed in the return duct or the occupied space.

The EconoMi$er+ control algorithm modulates the position

of the EconoMi$er+ damper between two user configurations

depending upon the relationship between the IAQ and the

Outdoor Air Quality (OAQ). The lower of these two positions

is referred to as the Minimum IAQ Minimum EconoMi$er+

Position (IAQMIN_SP).

The higher position is referred to as the Occupied EconoMi$er+

Minimum Position (ECONOMIN_SP). The IAQMIN_SP should

be set to an EconoMi$er+ position that brings in enough fresh

air to remove contaminants and CO2 generated by sources

other than people. The ECONOMIN_SP should be set to an

EconoMi$er+ position that brings in enough fresh air to remove

contaminants and CO2 generated by all sources including peo-

ple at the design value for maximum occupancy.

A reference differential CO2 level above the outside CO2

level is used as the starting point for IAQ control and

another reference differential level for maximum ventilation

at design occupancy is used for the end of IAQ control.

Between these points the control will modulate the dampers

open from the IAQMIN_SP and the ECONOMIN_SP set-

points. The damper position will never go above

ECONOMIN_SP or below IAQMIN_SP.

The control does not measure the outdoor IAQ reference

level as these levels are relatively constant. The installer

should take a measurement at start-up of the unit and enter

this value into the control using the Outdoor Air IAQ refer-

ence level configuration.

The control is configured for air quality sensors which pro-

vide 4 mA at 0 ppm and 20 mA at 2000 ppm. If a sensor has

a different range, these bounds must be reconfigured.

To configure the control for an IAQ sensor perform the fol-

lowing steps:

1. Determine the Occupied EconoMi$er+ Minimum posi-

tion (ECONOMIN_SP) and enter it into the control.

2. Determine the IAQ minimum EconoMi$er+ position

(IAQMIN_SP) and enter it into the control.

3. Enable IAQ control using IAQ Enable (IAQ_FLG).

4. Determine the Outdoor Air IAQ Reference (OAQ) and

enter it into the control.

NOTE: The value entered into the control will be the CO2

ppm level divided by 10. For example, 400 ppm would be

entered as 40.

5. Determine the lower control point differential level

(DAQLO) and enter it into the control. This is a dif-

ferential level so if the desired level to start IAQ con-

trol is 500 ppm and the OAQ reference level is 400

then a value of 100 would be used.

NOTE: The value entered into the control will be the CO2

ppm level divided by 10. For example 100 ppm would be

entered as 10.

6. Determine the upper control point differential level

(DAQHI) and enter it into the control. This is a differ-

ential level so if the desired level to start IAQ control

is 1100 ppm and the OAQ reference level is 400 then

a value of 700 would be used.

NOTE: The value entered into the control will be the CO2

ppm level divided by 10. For example 700 ppm would be

entered as 70.

D. Power Exhaust Configuration

The EconoMi$er+ can control up to 2 stages of power

exhaust. Power exhaust activation is done through config-

urable damper position set points. The first stage of power is

controlled by relay C4 on the EconoMi$er+ board. The acti-

vation point for the first stage is set using the Power

Exhaust Stage 1 Activation set point (PE_SP1). The second

stage of power exhaust must be set at a value greater than

the first stage. It is configured using the Power Exhaust

Stage 2 Activation set point (PE_SP2).

XVIII. OPERATING SEQUENCE

A. Cooling, Units Without EconoMi$er+

When thermostat calls for cooling, terminals G and Y1 and

the compressor contactor (C) are energized. The indoor (evap-

orator) fan motor (IFM), compressor, and outdoor (condenser)

fan motor (OFM) start. The OFM runs continuously while the

unit is in cooling. When the thermostat is satisfied, C is deen-

ergized and the compressor and OFM shut off. After a

30-second delay, the (IFM) shuts off. If the thermostat fan

selector switch is in the ON position, the evaporator motor

will run continuously.

B. Heating, Units Without EconoMi$er+

When the thermostat calls for heating, terminal W1 is ener-

gized. The induced-draft motor is energized and the burner

ignition sequence begins. The indoor (evaporator) fan motor

(IFM) is energized 45 seconds after a flame is ignited. When

additional heat is needed, W2 is energized and the high-fire

solenoid on the main gas valve (MGV) is energized. When

the thermostat is satisfied and W1 is deenergized, the IFM

stops after a 45-second time-off delay.

C. Cooling, Units WithEconoMi$er+

For EconoMi$er+ operation, there must be a thermostat call

for the fan (G). This will move the damper to its minimum

position.

When the EconoMi$er+ control is the occupied mode and a

call for cooling exists (Y1 on the thermostat), the control will

first check for indoor fan operation. If the fan is not on, then

cooling will not be activated. If the fan is on, then the control

will open the EconoMi$er+ damper to the minimum position.

On the initial power to the EconoMi$er+ board, it will take

the damper up to 21/2 minutes before it begins to position

itself. With subsequent fan signal (G) to the board, the

change in damper position will take up to 30 seconds to ini-

tiate. Damper movement from full closed to full open (or vice

versa) will take 21/2 minutes.

If the damper is in the process of a change (for example going

to 100% open) and the signal (G) is turned off, the damper

will continue to open to 100% before it closes (due to no fan

signal [G]).

If free cooling can be used as determined from the appropri-

ate changeover command (switch, dry bulb, enthalpy curve,

differential dry bulb, or differential enthalpy), then the con-

trol will modulate the dampers open to main the supply air

temperature set point plus 2° F.

If there is a further demand for cooling (cooling second stage

— Y2 is energized), then the control set point for the leaving

air will be set at the supply air set point to increase the cool-

ing capacity. If this cannot satisfy the load then the control

will bring on compressor stages as needed to maintain the

supply air temperature set point. The EconoMi$er+ damper

will be locked open at 100% or the maximum damper posi-

tion set point.

To ensure that there is oil return, the compressors will oper-

ate for at least 3 minutes. If, during this period, the leaving

temperature drops below the set point by 5° F, then the

EconoMi$er+ dampers will be closed to 60% until the com-

pressor is turned off to avoid cold leaving air temperatures.

If the conditions are not suitable for free cooling then the

EconoMi$er+ dampers will be closed to the minimum venti-

lation position.

Compressor stages will be used to cool the air. If the control

is configured for direct control by Y1 and Y2, then the stages

will sequence based on the demand of Y1 and Y2. If the

control is configured for leaving air temperature control,

then Y1 will maintain the leaving air temperature at the

supply air set point plus 2° F. If Y1 and Y2 are closed, then

the leaving air will be controlled to the supply air set point.

If Y2 is closed and Y1 is open, then control will shut down

and indicate an error due to a thermostat failure or improper

wiring of the thermostat.

If the unit is in the unoccupied mode, then the control of the

temperature will depend on the unoccupied free cooling con-

figuration: no unoccupied cooling, unoccupied free cooling

with any mechanical cooling, or unoccupied free and

mechanical cooling. If free cooling is enabled, then the con-

trol will check if free cooling can be used. The EconoMi$er+

will then control to the leaving air temperature set point

plus 2° F for a Y1 command, or the leaving air temperature

set point for a Y1 and Y2 command. If mechanical cooling is

allowed to be used, then the control will then bring on addi-

tional stages of mechanical cooling if free cooling cannot sat-

isfy the load.

If the EconoMi$er+ control:

• is in the occupied mode

• is configured to use demand ventilation

• cannot use free cooling

• has return air or space CO2 levels below the DAQLO

limit,

then the EconoMi$er+ damper position will be set to the

IAQMIN_SP set point. If the CO2 level rises above the

DAQLO limit, then the dampers will modulate open in a lin-

ear relationship until the return air or space CO2 levels are

at or above the DAQHI limit. The damper position will be at

the ECONOMIN_SP set point.

When the EconoMi$er+ is being used for free cooling and the

position exceeds the power exhaust set point, then the con-

trol will turn on the appropriate power exhaust fans. Refer to

Fig. 23 for barometric relief capacity, Fig. 24 for outdoor air

leakage, and Fig. 25 for pressure drop.

Unoccupied and Occupied Minimum Position Control

There is an unoccupied minimum damper position and an

occupied minimum damper position on the EconoMi$er+

controller. When the HVAC fan is off the outdoor air damper

will always be closed. When the fan is on and in the unoccu-

pied mode, the outdoor air damper will be at the unoccupied

minimum position. When the fan is on (G call) and in the

occupied mode, the outdoor air damper will be at the occu-

pied minimum position.

A jumper wire is factory-installed to force the unit into occu-

pied configuration whenever G or Y1 are closed. Without the

jumper wire, the unit will always be in unoccupied mode.

The 2 minimum position settings are also used in the

IAQ sequence of operation. See Indoor Air Quality Sensor on

page 21.

NOTE: The minimum position signal takes priority over the

maximum position signal. If the maximum damper position is

set below the minimum damper position, the EconoMi$er+

controller will maintain the actuator at minimum position.

—61—

Adjust the unoccupied minimum position to allow the mini-

mum amount of outdoor air, as required by local codes, to

enter the building. Make minimum position adjustments

with at least 10 F (6 C) temperature difference between the

outdoor and return air temperatures.

To determine the unoccupied minimum position setting, per-

form the following procedure:

Calculate the appropriate supply-air temperature using the

following formula: (TO x OA) + (TR x RA) = TM

TO = Outdoor-Air Temperature

OA = Percent of Outdoor Air

TR = Return-Air Temperature

RA = Percent of Return Air

TM = Supply-Air Temperature

As an example, if local codes require 10% outdoor air during

occupied conditions, outdoor-air temperature is 60 F, and

return-air temperature is 75 F:

(60 x 0.10) + (75 x 0.90) = 73.5 F

Carefully adjust the unoccupied minimum position until the

measured supply-air temperature matches the calculated

value. Then, carefully adjust the occupied minimum position

set point on the controller until the desired position is

reached.

D. Heating, Units WithEconomizer+

When the thermostat calls for heating, terminal W1 is ener-

gized. The induced-draft motor is energized and the burner

ignition sequence begins. The indoor (evaporator) fan motor

(IFM) is energized 45 seconds after a flame is ignited. When

additional heat is needed, W2 is energized and the high-fire

solenoid on the main gas valve (MGV) is energized. When

the thermostat is satisfied and W1 is deenergized, the

IFM stops after a 45-second time-off delay. The economizer

damper moves to the minimum position. When the thermo-

stat is satisfied, the damper moves to the fully closed

position.

switch opens at 30 F and closes at 45 F. No adjustment is

necessary. Refer to Tables 1A and 1B.

XI. CHECKING AND ADJUSTING REFRIGERANT CHARGE

The refrigerant system is fully charged with R-22 refriger-

ant, tested, and factory-sealed. Unit must operate in Cooling

mode a minimum of 10 minutes before checking charge.

NOTE: Adjustment of the refrigerant charge is not required

unless the unit is suspected of not having the proper R-22

charge.

A superheat charging chart is attached to the outside of the

service access panel. The chart includes the required suction

line temperature at given suction line pressures and outdoor

ambient temperatures.

An accurate superheat, thermocouple-type or thermistor-

type thermometer, and a gage manifold are required when

using the superheat charging method for evaluating the unit

charge. Do not use mercury or small dial-type thermometers

because they are not adequate for this type of measurement.

CAUTION: When evaluating the refrigerant

charge, an indicated adjustment to the specified fac-

tory charge must always be very minimal. If a substan-

tial adjustment is indicated, an abnormal condition

exists somewhere in the cooling system, such as insuf-

ficient airflow across either coil or both coils.

Proceed as follows:

1. Remove caps from low-pressure and high-pressure

Schrader valve fittings.

2. Using hoses with valve core depressors, attach

low- and high-pressure gage hoses to low-pressure

and high-pressure service fittings, respectively.

3. Start unit in Cooling mode and let unit run until sys-

tem pressure stabilize.

4. Measure and record the following:

a. Outdoor ambient-air temperature (F db).

b. Evaporator inlet-air temperature (F wb).

c. Suction-tube temperature (F) at low-side service

fitting.

d. Suction (low-side) pressure (psig).

5. Using “Cooling Charging Charts” compare outdoor-

air temperature (F db) with the suction line pressure

(psig) to determine desired system operating suction

line temperature. See Fig. 41-48.

6. Compare measured suction-tube temperature with

desired suction-tube temperature. Using a tolerance

of ± 3° F, add refrigerant if measured temperature is

more than 3° F higher than proper suction-tube tem-

perature, or remove refrigerant if actual temperature

is more than 3° F lower than required suction-tube

temperature.

A. To Use Cooling Charging Chart

This method is to be used in Cooling mode only. Take the out-

door ambient temperature and read the suction pressure

gage. Refer to appropriate chart to determine what suction

temperature should be. If suction temperature is high, add

refrigerant. If suction temperature is low, carefully recover

some of the charge. Recheck the suction pressure as charge

is adjusted. Example (Fig. 44, Circuit 2):

XII. FLUE GAS PASSAGEWAYS

To inspect the flue collector box and upper areas of the heat

exchanger:

1. Remove the combustion blower wheel and motor

assembly according to directions in Combustion-Air

Blower section below.

2. Remove the flue cover to inspect the heat exchanger.

3. Clean all surfaces as required using a wire brush.

XIII. COMBUSTION-AIR BLOWER

Clean seasonally to assure proper airflow and heating effi-

ciency. Inspect blower wheel every fall and periodically dur-

ing heating season. For the first heating season, inspect

blower wheel bimonthly to determine proper cleaning

frequency.

To inspect blower wheel, shine a flashlight into draft hood

opening. If cleaning is required, remove motor and wheel as

follows:

1. Slide burner access panel out.

2. Remove the 6 screws that attach induced-draft motor

housing to vestibule plate (Fig. 49).

3. The blower wheel can be cleaned at this point. If

additional cleaning is required, continue with Steps 4

and 5.

4. To remove blower from the motor shaft, remove

2 setscrews.

5. To remove motor, remove the 4 screws that hold

blower housing to mounting plate. Remove the motor

cooling fan by removing one setscrew. Then remove

nuts that hold motor to mounting plate.

6. To reinstall, reverse the procedure outlined above.

XIV. LIMIT SWITCH

Remove blower access panel (Fig. 1A and 1B). Limit switch is

located on the fan deck. Verify operation of limit by tempo-

rarily blocking return air until limit trips.

XV. BURNER IGNITION

Unit is equipped with a direct spark ignition 100% lockout

system. Integrated Gas Unit Controller (IGC) is located in

the control box (Fig. 11). Module contains a self-diagnostic

LED. A single LED on the IGC provides a visual display of

operational or sequential problems when the power supply is

interrupted. When a break in power occurs, the module will

be reset (resulting in a loss of fault history) and the indoor

(evaporator) fan ON/OFF times will be reset. For additional

information, refer to the Start-Up, Heating section on

page 51. The LED error code can be observed through the

viewport. See Fig. 11. During servicing refer to the label on

the control box cover or Table 36 for an explanation of LED

error code descriptions.

If lockout occurs, unit may be adjusted by interrupting

power supply to unit for at least 5 seconds.

XVI. MAIN BURNERS

At the beginning of each heating season, inspect for deterio-

ration, blockage due to corrosion or other causes. Observe

the main burner flames and replace burners if necessary.

A. Removal and Replacement of Gas Train (Fig. 49 and 50)

1. Shut off manual gas valve.

2. Shut off power to unit and install lockout tag.

3. Slide out burner section side panel (not shown).

4. Disconnect gas piping at unit gas valve using backup

wrench on the flats of the valve body where the gas

pipe enters the gas valve. See Fig. 49.

ing analysis.

LEGEND

SYMPTOM CAUSE REMEDY

Hardware Failure.

(LED OFF)

Loss of power to control module (IGC). Check 5 amp fuse on IGC, power to unit, 24-v circuit breaker, and

transformer. Units without a 24-v circuit breaker have an internal

overload in the 24-v transformer. If the overload trips, allow

10 minutes for automatic reset.

Fan ON/OFF Delay Modified

(LED/FLASH)

High limit switch opens during heat

exchanger warm-up period

before fan-on delay expires.

Limit switch opens within three

minutes after blower-off delay

timing in Heating mode.

Ensure unit is fired on rate and temperature rise is correct.

Ensure unit’s external static pressure is within application guidelines.

Limit SwitchFault.

(LED 2 flashes)

High temperature limit switch is open. Check the operation of the indoor (evaporator) fan motor.

Ensure that the supply-air temperature rise is in accordance with the range on the

unit nameplate.

Flame Sense Fault.

(LED 3 flashes)

The IGC sensed flame that

should not be present.

Reset unit. If problem persists, replace control board.

4 Consecutive Limit SwitchFaults.

(LED 4 flashes)

Inadequate airflow to unit. Check operation of indoor (evaporator) fan motor and that supply-air

temperature rise agrees with range on unit nameplate information.

Ignition Lockout.

ignition for 15 minutes.

Check ignitor and flame sensor electrode spacing, gaps, etc.

Ensure that flame sense and ignition wires are properly terminated.

Verify that unit is obtaining proper amount of gas.

Induced-Draft Motor Fault.

(LED 6 flashes)

IGC does not sense that

induced-draft motor is operating.

Check for proper voltage. If motor is operating, check the

speed sensor plug/IGC Terminal J2 connection. Proper

connection: PIN 1— White, PIN 2 — Red, PIN 3 — Black.

Rollout SwitchFault.

(LED 7 flashes)

Rollout switch has opened. Rollout switch will automatically reset, but IGC will continue to lock

out unit. Check gas valve operation. Ensure that induced-draft blower

wheel is properly secured to motor shaft. Reset unit at unit disconnect.

Internal Control Fault.

(LED 8 flashes)

Microprocessor has sensed an

error in the software or hardware.

If error code is not cleared by resetting unit power, replace the IGC.

Temporary Software Lockout

(LED 9 flashes)

Electrical interference is impeding the IGC

software

Reset 24-v to control board or turn the thermostat off and on. Fault will automatically

reset itself in one hour.

CAUTION: If the IGC must be replaced, be sure to ground your-

self to dissipate any electrical charge that may be present before handling

new control board. The IGC is sensitive to static electricity and may be

damaged if the necessary precautions are not taken. IGC — Integrated Gas Unit Controller
