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 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 duct configuration. To convert to

horizontal configuration, remove screws from side duct open-

ing 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, not to the unit. The accessory

thru-the-bottom power and gas connection package must be

installed before the unit is set on the roof curb. If field-

installed (thru-the-roof curb) gas connections are desired, use

factory-supplied 3/4-in. pipe coupling and gas plate assembly

to mount the thru-the-roof curb connection to the roof curb.

Gas connections and power connections to the unit must be

field installed after the unit is installed on the roof curb.

If electric and control wiring is to be routed through the

basepan, attach the accessory thru-the-bottom service con-

nections to the basepan in accordance with the accessory

installation instructions.

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

result in air 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.

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.

WARNING: Before performing service or mainte-

nance operations on unit, turn off main power switch

to unit and install a lockout tag. Electrical shock could

cause personal injury.

CAUTION: Ensure voltage listed on unit data plate

agrees with electrical supply provided for the unit.

B. Slab Mount (Horizontal Units Only)

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

beyond unit cabinet. Install a 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.

C. Alternate Unit Support

A non-combustible sleeper rail can be used in the unit curb

support area. If sleeper rails cannot be used, support the

long sides of the unit with a minimum of 3 equally spaced

4-in. x 4-in. pads on each side.

II. STEP 2 — FIELD FABRICATE DUCTWORK

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

cal ducted units. Do not connect ductwork to unit. For hori-

zontal applications, field-supplied flanges should be attached

to horizontal duct openings and all ductwork should be

secured to the flanges. Insulate and weatherproof all exter-

nal ductwork, 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 –.20 in. wg with

economizer or –.45 in. wg without economizer.

These units are designed for a minimum continuous heating

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 con-

nection 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 installation,

relocate the factory-installed plug (Red) from the bottom con-

nection to the side connection. The center drain plug looks like

a star connection, however it can be removed with a 1/2-in.

socket drive. 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 drainage.

Install a trap at least 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.

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 Table 1 and Fig. 6 for

additional information.

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

and 1B. Refer to rigging instructions on unit.

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. A properly positioned

unit will have the following clearances between unit and roof

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

each side and duct end of unit; 1/4-in. clearance between roof

curb and condenser coil end of unit. (See Fig. 3, section C-C.)

CAUTION: All panels must be in place when rigging.

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 such 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.

Flue vent discharge must have a minimum horizontal clear-

ance of 4 ft from electric and gas meters, gas regulators, and

gas relief equipment.

Minimum distance between unit and other electrically live

parts is 48 inches.

Flue gas can deteriorate building materials. Orient unit such

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

complies with all local codes and Section 5.3, Air for Combus-

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

ANSI (American National Standards Institute) Z223.1, and

NFPA (National Fire Protection Association) 54 TIA-54-84-1.

In Canada, installation must be in accordance with the

CAN1-B149 installation codes for gas burning appliances.

After unit is in position, remove rigging skids and shipping

materials.

V. STEP 5 — INSTALL FLUE HOOD

Flue hood is shipped screwed to the basepan beside 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 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 appliances.

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

nection must not be less than 4 in. wg or greater than

13.0 in. wg while unit is operating. On 580F048,060,072 high

heat units, the gas pressure at unit gas connection must not

be less than 5 in. wg or greater than 13 in. wg while the unit

is operating. For propane applications, the gas pressure

must not be less than 5 in. wg or greater than 13 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 connec-

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

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

support beam every 8 ft. Therefore, an 18-ft long gas pipe

would have a minimum of 2 support beams, a 48-ft long pipe

would have a minimum of 6 support beams.

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

manual main shutoff valve.

CAUTION: When connecting the gas line to the

unit gas valve, the installer MUST use a backup

wrench to prevent valve damage.

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 with the 1/4-in. female

space connector from the 230-volt connection and moving to

the 208-volt 1/4-in. male terminal on the primary side of the

transformer.

Refer to unit label diagram for additional information.

Pigtails are provided for field wire connections. Use factory-

supplied splices or UL (Underwriters’ Laboratories)

approved copper/aluminum connector.

When installing units, provide a disconnect per the NEC.

All field wiring must comply with NEC and local require-

ments.

Install field wiring as follows:

1. Install conduit through side panel openings. Install

conduit between disconnect and control box.

2. Install power lines to terminal connections as shown

in Fig. 9.

Voltage to compressor terminals during operation must be

within voltage range indicated on unit nameplate (see

Tables 2A and 2B). On 3-phase units, voltages between

phases must be balanced within 2% and the current within

10%. Use the formula shown in the legend for Tables 2A and

2B, Note 2 to determine the percent of voltage imbalance.

Operation on improper line voltage or excessive phase imbal-

ance constitutes abuse and may cause damage to electrical

components. Such operation would invalidate any applicable

Bryant warranty.

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. Connect

thermostat wires to terminal board.

Route thermostat cable or equivalent single leads of colored

wire from subbase terminals through connector on unit to

low-voltage connections (shown in Fig. 10).

NOTE: For wire runs up 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.

Pass the control wires through the hole provided in the cor-

ner post; then 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 clearance between high-voltage and low-voltage

wiring.

C. Heat Anticipator Settings

Set heat anticipator settings at .14 amp for the first stage

and .14 amp for second-stage heating, when available.

WARNING: Unit cabinet must have an uninter-

rupted, unbroken electrical ground to minimize the possi-

bility 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 accor-

dance with NEC (National Electrical Code), ANSI/NFPA,

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 per-

sonal injury of others.BLOWER

*Used to determine minimum disconnect per NEC.

†Fuse or HACR circuit breaker.

NOTES:

1. In compliance with NEC requirements for multimotor and combination load equipment (refer

to NEC Articles 430 and 440), the overcurrent 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=5v

(BC) 464 – 457 =7v

(AC)457–455=2v

Maximum deviation is 7 v.

Determine percent of voltage imbalance.

=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.

3. For units with power exhaust: If a single power source is to be used, size wire to include

power exhaust MCA and MOCP. Check MCA and MOCP when power exhaust is powered

through the unit (must be in accordance with NEC and/or local codes). Determine the new

MCA including the power exhaust using the following formula:

MCA New =MCA unit only +MCA of Power Exhaust

For example, using a 580F060 unit with MCA =28.9 and MOCP =35, with

CRPWREXH030A00 power exhaust.

MCA New =28.9 amps +1.6 amps =30.5 amps

If the new MCA does not exceed the published MOCP, then MOCP would not change. The

MOCP in this example is 35 amps, the MCA New is below 35, 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.

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

temperature is above the set point then the EconoMi$er

should be in minimum position. If the outdoor air tempera-

ture 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 outside air enthalpy changeover con-

trol. This mode requires a factory-supplied outdoor air tem-

perature 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 opera-

tion of the sensors using the Read function.

Differential Enthalpy Changeover

The control supports differential enthalpy changeover con-

trol. This requires the factory-supplied outside 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

position. Refer to the setup examples on page 42.

E. EconoMi$er+ Controller Wiring

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

air temperature sensor and an outside air temperature sen-

sor. This allows for operation of the EconoMi$er+ with out-

side air dry bulb changeover control. Additional accessories

can be added to allow for different types of change over con-

trol 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 thermo-

stat terminal connection 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 IAQ sensor.

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 sen-

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

airstream. The operating range of temperature measure-

ment is 0° to 158 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 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° to 158 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 con-

troller. 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 econo-

mizer 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

accessory 10K return air temperature sensor

(CRTEMPSN001A00) in addition to the outdoor air tempera-

ture 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 har-

ness should be routed from the EconoMi$er+ controller to the

sensor. The controller compares the temperatures of the two

airstreams, chooses the best one, and modulates 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

temperature 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 pro-

vides 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 econo-

mizer damper positions and to control how mechanical cool-

ing 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.

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

occupied 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 instruc-

tions 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+ control-

ler. See Fig. 22. The pink wire from the harness is connected

to pin 15 (ground symbol). The gray wire from the harness is

connected 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

controller. The occupied minimum position set point config-

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

using a remote potentiometer. The occupied minimum posi-

tion 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 position

below the normal minimum position based on full occupancy.

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 venti-

lation control, the damper position will be between

IAQMIN_SP and ECONOMIN_SP. The upper IAQ differen-

tial 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.

Normally, 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. CO

Sensor Configuration

The CO2 sensor has preset standard voltage settings that

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

Table 7.

onds 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 2 times. 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

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 Ven-

tilation (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.

shows fan rpm at motor pulley settings. Table 9 shows motor

performance. Refer to Tables 10-33 to determine fan speed

settings.

A. Direct-Drive Motors

The evaporator-fan motor factory speed setting is shown on

label diagram affixed to base unit. If other than factory set-

ting is desired, refer to label diagram for motor reconnection.

See Fig. 33 for direct drive motor location.

B. Belt-Drive Motors

Fan motor pulleys are factory set for speed shown in Table 1.

See Fig. 34 for belt drive motor location.

NOTE: Before adjusting fan speed, make sure the new fan

speed will provide an air temperature rise range as shown in

Table 1.

To change fan speed:

1. Shut off unit power supply and tag disconnect.

2. Loosen belt by loosening fan motor mounting nuts.

See Fig. 34.

3. Loosen movable pulley flange setscrew (see Fig. 35).
