WARNING: Disconnect gas piping from unit when
leak testing at pressure greater than 1/2 psig. Pressures greater than 1/2 psig will cause gas valve damage
resulting in hazardous condition. If gas valve is subjected to pressure greater than 1/2 psig, it must be
replaced before use. When pressure testing fieldsupplied gas piping at pressures of 1/2 psig or less, a
unit connected to such piping must be isolated by manually closing the gas valve.
WARNING: Before performing service or maintenance 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.
INSTALLATION
Unit is shipped in the vertical duct 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. Ductwork 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 fieldinstalled (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 connections 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.

Fig. 2 — Horizontal Conversion Panels
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 vertical ducted units. Do not connect ductwork to unit. For horizontal applications, field-supplied flanges should be attached
to horizontal duct openings and all ductwork should be
secured to the flanges. Insulate and weatherproof all external ductwork, joints, and roof openings with counter flashing
and mastic in accordance with applicable codes.
Ducts passing through an unconditioned space must be insulated and covered with a vapor barrier.

III. STEP 3 — INSTALL EXTERNAL TRAP FOR CONDENSATE 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 installation,
relocate the factory-installed plug (Red) from the bottom connection 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

If a plenum return is used on a vertical unit, the return
should be ducted through the roof deck to comply with applicable fire codes.
A minimum clearance is not required around ductwork. Cabinet return air static shall not exceed –.20 in. wg with
economizer or –.45 in. wg without economizer.

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.

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.

Lifting holes are provided in base rails as shown in Fig. 1A
and 1B. Refer to rigging instructions on unit.

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 temperatures are used with insufficient heating temperature rise.

A. Positioning

CAUTION: All panels must be in place when rigging.

Maintain clearance around and above unit to provide minimum 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.)

VI. STEP 6 — INSTALL GAS PIPING
Unit is equipped for use with type of gas shown on nameplate. 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 connection 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.

NOTE: Trap should be deep enough to offset maximum unit static difference. A 4-in. trap is recommended.

Fig. 5B — External Trap Condensate Drain
Do not install unit in an indoor location. Do not locate unit
air inlets near exhaust vents or other sources of contaminated air.

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
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.

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.

VII. STEP 7 — MAKE ELECTRICAL CONNECTIONS
WARNING: Unit cabinet must have an uninterrupted, 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,
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.

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 factorysupplied 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 requirements.
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 imbalance 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 accordance 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 corner 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.

Maximum deviation is 7 v.
Determine percent of voltage imbalance.
7
% Voltage Imbalance = 100 x
457
= 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.

Example: Supply voltage is 460-3-60.

Maximum deviation is 7 v.
Determine percent of voltage imbalance.
7
% Voltage Imbalance = 100 x
457
= 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.

Example: Supply voltage is 460-3-60.

All temperature adjustments are made at the EconoMi$er+ controller.

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 controller. 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.

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
airstream. The operating range of temperature measurement is 0° to 158 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 measurement is 0° to 158 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 EconoMi$er+ Controller section.

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

L. Indoor Air Humidity Sensor
For differential enthalpy sensing, the EconoMi$er+ controller uses the standard outdoor air temperature sensor, the
outdoor air humidity sensor, and the optional indoor air
humidity sensor, an optional return air temperature sensor
(RAT). The indoor-air humidity sensor is provided with a
2-wire, 42-in. wiring harness with a 2-pin connector. The
plug is installed on pins 8 and 9 on J3 of the EconoMi$er+
controller. The pins are labeled IRH and VREF on the
EconoMi$er+ controller. See Fig. 22. The orange wire of the
harness is connected to pin 8 (IRH). The blue wire of the harness is connected to pin 9 (VREF). The wiring harness
should be extended with wires and wire nuts and routed
from the EconoMi$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 outdoor) for cooling. For example, when the outdoor air has a
lower enthalpy than the return air, the EconoMi$er+ controller opens the damper to bring in outdoor air for free cooling.

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.

The accessory 5-in wiring plug, CRE+PLUG001A00 is
required to connect the potentiometer.

M. Occupied/Unoccupied Switch
The EconoMi$er+ supports the use of a field-supplied
occupied/unoccupied switch. When the switch is closed it provides a 24-vac signal to the unit for occupied mode and when
open, there is no signal to indicate unoccupied mode. The
control can be configured to allow different minimum economizer damper positions and to control how mechanical cooling will and will not be used in the occupied mode.
NOTE: The remote potentiometer (see below) will override
the occupied minimum position if the potentiometer setting
is greater than the occupied minimum position.
A wire from J1-OCC (pin 4) and a wire from J1-24V (pin 5)
are wire-nutted together to jumper the terminals.
An occupied/unoccupied switch can be field-installed in place
of the jumper to allow the user to force the control into
occupied or unoccupied mode of operation for EconoMi$er+
damper position. The occupied/unoccupied switch is required
if the user wants to use unoccupied free cooling or different
EconoMi$er+ damper vent positions in the unoccupied mode.
N. Power Exhaust
Refer to the Accessory Power Exhaust installation instructions for information on installing the power exhaust
accessory.
O. Remote EconoMi$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. Remote Potentiometer Occupied Minimum Position
The occupied minimum position set point remote potentiometer (field-supplied) is used when requiring additional temporary ventilation. The remote potentiometer (10K ohm closed damper, 100K ohm - open damper) will only control
the occupied minimum position.

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
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$er+ controller to the remote potentiometer
location.
NOTE: Pins 13 (ground symbol) and 14 (IAQ), which are
wired to the accessory 5-pin plug, are not used for the remote
potentiometer installation. They are used for an accessory
IAQ sensor (if required).
The unoccupied minimum position can only be set at the
controller. The occupied minimum position set point configured at the EconoMi$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$er+ controller unoccupied minimum position, then the remote potentiometer setting will be used. The
remote potentiometer is field supplied and must be a 3-wire,
linear potentiometer with a resistance between 10K ohm
and 100K ohm (such as the Honeywell S963B1128).
Q. Demand Ventilation Control
Demand ventilation control uses an IAQ sensor
(CRE+PLUG001A00 required) to control the amount of outside air admitted into the system. Normally, the minimum
position of the EconoMi$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 unoccupied minimum position (configuration item number 3). If
there is an IAQ signal the damper will be in the occupied

—22—

minimum position (configuration item number 15), unless
the remote potentiometer is used to override it.

S. Dehumidification of Fresh Air with Demand Control Ventilation (DCV)

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.
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.

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 introduced. 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 processes 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.

The following equation is used to determine EconoMi$er+
damper position (ECONOMIN_POS):
IAQMIN_SP + =

(ECONOMIN_SP – IAQMIN_SP) * (IAQ – OAQ – DAQLO)
(DAQHI – DAQLO)

R. CO2 Sensor 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 custom 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 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 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.

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.

IX. STEP 9 — ADJUST EVAPORATOR-FAN SPEED
Adjust evaporator-fan rpm to meet jobsite conditions. Table 8
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 setting 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).
4. Screw movable flange toward fixed flange to increase
speed and away from fixed flange to decrease speed.
Increasing fan speed increases load on motor. Do not
exceed maximum speed specified in Table 1.
5. Set movable flange at nearest keyway of pulley hub
and tighten setscrew. (See Table 1 for speed change
for each full turn of pulley flange.)
To align fan and motor pulleys:

Fig. 33 — Direct-Drive Motor Mounting

1. Loosen fan pulley setscrews.
2. Slide fan pulley along fan shaft.
3. Make angular alignment by loosening motor from
mounting.
To adjust belt tension:
1. Loosen fan motor mounting nuts.
2. Slide motor mounting plate away from fan scroll for
proper belt tension (1/2-in. deflection with 8 to 10 lb of
force).
3. Tighten motor mounting nuts.
4. Adjust bolt and tighten nut to secure motor in fixed
position.

NOTES:
1. Boldface indicates field-supplied drive is required.
2. Maximum continuous bhp is 2.90.
3. See below for general fan performance notes.

*Motor drive range: 1300 to 1685 rpm. All other rpms require a field-supplied
drive.

GENERAL FAN PERFORMANCE NOTES
1. Values include losses for filters, unit casing, and wet coils.
2. Extensive motor and electrical testing on these units ensures that
the full range of the motor can be utilized with confidence. Using
your fan motors up to the wattage ratings shown will not result in
nuisance tripping or premature motor failure. Unit warranty will not
be affected. See Table 9 — Motor Data for additional information.

—36—

3. Use of a field-supplied motor may affect wire sizing. Contact your
Bryant representative for details.
4. Interpolation is permissible. Do not extrapolate.

sure Start-Up Checklist on back page is filled out and
completed.

PRE-START-UP
WARNING: Failure to observe the following warnings
could result in serious personal injury.
1. Follow recognized safety practices and wear protective
goggles when checking or the servicing refrigerant
system.
2. Do not operate the compressor or provide any electric
power to the unit unless the compressor terminal cover is in place and secured.
3. Do not remove the compressor terminal cover until all
electrical sources are disconnected.
4. Relieve all pressure from the system before touching
or disturbing anything inside the compressor terminal
box if refrigerant leak is suspected around the compressor terminals.
5. Never attempt to repair a soldered connection while
the refrigerant system is under pressure.
6. Do not use torch to remove any component. The system contains oil and refrigerant under pressure. To remove a component, wear protective goggles and
proceed as follows:
a. Shut off gas and then electrical power to the unit.
Install lockout tag.
b. Relieve all pressure from the system using both
high-pressure and low-pressure ports.
c. Cut the component connection tubing with a tubing
cutter, and remove the component from the unit.
d. Carefully unsweat the remaining tubing stubs when
necessary. Oil can ignite when exposed to torch
flame.

II. RETURN-AIR FILTERS
Make sure correct filters are installed in filter tracks. See
Table 1. Do not operate unit without return-air filters.
III. COMPRESSOR MOUNTING
Compressors are internally spring mounted. Do not loosen or
remove compressor holddown bolts.
IV INTERNAL WIRING
Check all electrical connections in unit control boxes.
Tighten as required. Ensure wiring does not come in contact
with refrigerant tubing.
V. GAS PIPING
Check gas piping for leaks.
WARNING: Disconnect gas piping from unit when
leak testing at pressure greater than 1/2 psig. Pressures greater than 1/2 psig will cause gas valve damage
resulting in hazardous condition. If gas valve is subjected to pressure greater than 1/2 psig, it must be
replaced before use. When pressure testing fieldsupplied gas piping at pressures of 1/2 psig or less, a
unit connected to such piping must be isolated by manually closing the gas valve.

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,
CAUTION, and INFORMATION labels attached to,
or shipped with, the 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 connections
and on unit base. Detecting oil generally indicates
a refrigerant leak. Leak-test all refrigerant tubing
connections using an electronic leak detector,
halide torch, or liquid-soap solution.
c. Inspect all field- and factory-wiring connections.
Be sure that connections are completed and tight.
d. Inspect coil fins. If damaged during shipping and
handling, carefully straighten the fins with a fin
comb.
4. Verify the following conditions:
a. Make sure that condenser fan blade is correctly
positioned in the fan orifice. See Condenser-Fan
Adjustment section on page 48 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

VI. REFRIGERANT SERVICE PORTS
To service refrigerant service ports, remove compressor
access panel. Each unit system has 4 Schrader-type service
gage ports: one on the suction line, one on the liquid line, and
two on the compressor discharge line. Be sure that caps on
the ports are tight. One of the Schrader-type valves on the
compressor discharge line is located under the low-pressure
switch.
The Schrader valve on the compressor discharge line that is
located under the high pressure switch does not contain a
Schrader core in the valve.
VII. 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 cannot be accessed for service in the field. Ensure the plastic
caps are in place and tight or the possibility of refrigerant
leakage could occur.
VIII. 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 pressure fittings.
2. Energize the compressor.
3. The suction pressure should drop and the discharge
pressure should rise, as is normal on any start-up.
If the suction pressure does not drop and the discharge pressure 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 tag disconnect.
3. Reverse any two of the unit power leads.
4. Reapply power to the unit.

The suction and discharge pressure levels should now move
to their normal start-up levels.

to 180 seconds. When one flash of the LED is observed, the
evaporator-fan ON/OFF delay has been modified.

NOTE: When the compressor is rotating in the wrong direction, the unit makes an elevated level of noise and does not
provide cooling.

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 minutes has
elapsed since the last call for heating.

IX. COOLING
Set space thermostat to OFF position. 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, outdoor fan
and evaporator motor start on closure of contactor.
Check unit charge. Refer to Service, Refrigerant Charge section, page 48.
Reset thermostat at a position above room temperature.
Compressor will shut off. Evaporator fan will shut off after
30-second delay.
To Shut Off Unit
Set system selector switch at OFF position. Resetting thermostat at a position above room temperature shuts unit off
temporarily until space temperature exceeds thermostat
setting.
X. MAIN BURNERS

The evaporator-fan OFF delay can also be modified. Once the
call for heating has ended, there is a 10-minute period during which the modification can occur. If the limit switch trips
during this period, the evaporator-fan OFF delay will
increase by 15 seconds. 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.
To Shut Off Unit
Set system selector switch at OFF position. Resetting heating selector lever below room temperature will temporarily
shut unit off until space temperature falls below thermostat
setting.
Table 34A — Altitude Compensation* — Standard Units

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 verify that the burners light and evaporator fan is energized.
After ensuring that the unit continues to heat the building,
lower the thermostat setting below 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. position.)
Refer to Table 34A and 34B for the correct orifice to use at
high altitudes.

XI. HEATING
1. Purge gas supply line of air by opening union ahead
of gas valve. If gas odor is detected, tighten union and
wait 5 minutes before proceeding.
2. Turn on electrical supply and manual gas valve.
3. Set system switch selector at HEAT position and fan
switch at AUTO. or ON position. Set heating temperature lever above room temperature.
4. The induced-draft motor will start.
5. After a call for heating, the main burners should light
within 5 seconds. If the burner does not light, then
there is a 22-second delay before another 5-second
try. If the burner still does not light, the time delay is
repeated. If the burner does 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 thermostat temperature is satisfied.
8. Adjust airflow to obtain a temperature rise within
the range specified on the unit nameplate.
NOTE: The default value for the evaporator-fan motor ON/
OFF delay is 45 seconds. The Integrated Gas Unit 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

XII. SAFETY RELIEF
A soft solder joint at the suction service Schrader port provides pressure relief under abnormal temperature and pressure conditions (i.e., fire in building).
XIII. VENTILATION (CONTINUOUS FAN)
Set fan and system selector switches at ON and OFF positions, 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.
XIV. 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 controller
is to provide control of the EconoMi$er+ dampers and the
cooling compression stages. The status of the indoor fan is
monitored through the G input but is not directly controlled
by the controller. The heating function is completely independent of the controller.
IMPORTANT: The controller can only be used with conventional thermostats with Y1, Y2 and G input to the controller;
it can NOT be used with electronic thermostats with a proportional room temperature input, or with Variable Air Volume systems.
There are 4 LEDs on the controller, which are used to read
values and display status and configuration information.
There are 2 buttons (READ/ADJUST and ADVANCE/ MANUAL), which change modes and configure the controller. See
Fig. 36.
The EconoMi$er+ microprocessor based control system provides 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 35 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 control, the four LEDs flash as shown in Table 36, 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 indicator 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) buttons are held for at least 3 seconds until all LEDs flash.
D. Read Mode
Read mode is used to check set points (Table 37) and I/O
channel status (Table 38). 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 button (#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
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) button 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 37) and then the I/O channels
(Table 38) 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 automatically 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 38. 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 channel status. To read the value again, push the READ/ADJUST
(#1) button.

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 configuration is a discrete On/off setting, push the READ/ADJUST
button (#1) to toggle LED 3 or 4 on or off.

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.

Setup Example 1: Change “Occupied Minimum Position”
(configuration item 2) to 53%.

If the channel is a digital output (relay), the DS3 LED (flashing green) will indicate ON status and the DS4 LED (flashing 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 follow 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 configuration 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 37 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 configuration 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 channel 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.

1. Read the General Notes about reading and entering
values found on the label on the top of the
EconoMi$er+.
2. Push and hold button #1 (READ/ADJUST) for at
least 3 seconds until all LEDs flash. The yellow LED
will go on steady.
3. Read the current configuration point by pushing button #1. The red LED flashes the configuration point
number and the green LEDs flash the current setting
for that setup point number.
4. On the label (on top of the EconoMi$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
setting.
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 minimum 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$er+.
2. Push and hold button #1 (READ/ADJUST) for at
least 3 seconds until all LEDs flash. The yellow LED
will go on steady.
3. Read the current configuration point by pushing button #1. The red LED flashes the configuration point
number and the green LEDs flash the current setting
for that setup point number.
4. On the label (on top of the EconoMi$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.

—42—

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 configuration 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 37) 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). However, 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 38.

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$er+ control outputs are turned off. “I/O
Inputs” 1-5 can be adjusted even if the unit is in operation.
In manual mode, the yellow DS2 LED flashes once to indicate the I/O channel. See Table 38. If the value is less than 5,
the yellow DS2 LED will count out the value using 1-second
flashes. If the value is greater than 4, the yellow DS2 LED
will count out groups of 5 at a high flash rate and then follow
with the additional value at a flash rate of once per
second. For example a flash of 1 indicates Compressor Relay
Output 1.
Push READ/ADJUST button (#1) to read the value. The yellow LED will flash the I/O Channel number being viewed.
Once the channel number is displayed it will then turn on
the appropriate green LED (DS3 or DS4) to indicate the status of the output. For relay outputs if the DS3 LED is on,
then the output is on. If DS4 is on, then the output is off. The
green DS3 and DS4 LEDs will remain on for about 2 seconds
and if during this time the READ/ADJUST (#1) button is
pushed, then the output will toggle to the alternate state. To
change again, push the READ/ADJUST button and repeat
the test or change the status of the output. As an example,
for channel 5 (EconoMi$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 buttons (#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 seconds 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 Troubleshooting section.
One 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.
XV. ECONOMI$ER+ CONFIGURATION
For most applications, the factory setting will be used to control the EconoMi$er+. However, there are 19 different variables that can be used to configure the control for wide range
of applications. The factory settings and variables are shown
in Table 37.

—43—

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$er+ control accepts an occupied/unoccupied
switch input. This input is used to control the occupied
and unoccupied minimum ventilation damper position as
shown in Table 37 items 2 (ECONOMIN_SP) and 3
(U_ECONOMIN_SP). These values represent the minimum
damper position. In addition, the controls allows for different
modes of compressor operation in the unoccupied mode.
Using item 13 in Table 37 (OCC_MODE), the user can select
one of the following unoccupied modes:
• No unoccupied cooling
• Unoccupied free cooling (EconoMi$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 energized 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 outside air
damper to the ventilation position. If the outside air conditions are acceptable, then the control will use the
EconoMi$er+ for free cooling. If the supply air temperature
does not meet the configurable set point, then the control
will turn on additional stages of mechanical cooling. Several
compressor sequences can be used depending on the application requirements; these will be covered in the mechanical
compressor staging section.
A. Compressor Configuration and Control
The EconoMi$er+ control can support from 1 to 4 compressor
stages. For the 3 to 12 1/2 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 37. 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 variable (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 temperature 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 control 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 37. The choices are:
1. Vent only — This is used to have just ventilation control. The EconoMi$er+ will not provide free cooling,
but the occupied and unoccupied minimum positions
can be used.
2. Proportional — In this configuration, full proportional EconoMi$er+ control will be used. When
EconoMi$er+ free cooling cannot be used, the dampers will be set to the appropriate occupied and unoccupied minimum positions.
3. Three-Position — This mode of EconoMi$er+ is used
to provide a minimum ventilation EconoMi$er+ position and a fixed free cooling or high ventilation position. The high ventilation position is controlled by the
optional Remote EconoMi$er+ Enable Switch Input
connected to terminals 11 and 12 on T3.
Supply Air Temperature Set Point
Once the type of EconoMi$er+ control has been selected, the
user will need to set the Supply Air Temperature set point
(SAT_SP). The SAT_SP has a range of 40 to 65 F.
NOTE: This will be the set point when both Y1 and Y2 are
closed. When just Y1 is closed, the set point will be 2 F
higher.
Minimum Damper Position
Set
the
occupied
minimum
damper
position
(ECONOMIN_SP) and unoccupied minimum position
(U_ECONOMIN_SP). These should be set to provide the
ventilation requirements at full occupancy as defined by the
building specifications. When demand ventilation is used,
the control will close the dampers below this position based
on measured CO2 levels in the space to provide additional
operation savings.
The control will also allow for the use of a remote minimum
position potentiometer. This will only adjust the Occupied
Minimum position. If used, the software set point
ECONOMIN_SP should be set to 0 as the control will use the
largest set point.
The damper position is not linear with the amount of outside
air, so the user will need to set the position of the
EconoMi$er+ accordingly. It is best to use the following equation and measured data to set the position:
OA =

SAT – RAT
*100
OAT – RAT

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.
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).

—44—

Compressor Lockout Temperature
Set the Compressor Lockout Temperature. The Compressor
Lockout Temperature (CMP_LOCK) is used to prevent compressor 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$er+ will be enabled based on the outside-air
temperature. The EconoMi$er+ is shipped with an
outside air temperature sensor. The outside air temperature set point can be configured by the user. The
EconoMi$er+ will be disabled when the outdoor-air
temperature rises above the set point. The configuration variable is the EconoMi$er+ Changeover set
point (OAT_SP).
3. Differential Dry Bulb — For this changeover setting,
the EconoMi$er+ will be enabled whenever the outside-air temperature is lower than the return-air
temperature. No configuration of set points is required other than to select the differential dry bulb
function.
4. Outdoor Enthalpy — For this changeover setting, the
control will enable the EconoMi$er+ based on the
outside-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$er+ will be enabled based on the comparison of the enthalpy of the return air and outside
air. If the outside air enthalpy is lower than the return air, then the EconoMi$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 people 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 setpoints. 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 reference level configuration.
The control is configured for air quality sensors which provide 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 following steps:
1. Determine the Occupied EconoMi$er+ Minimum
position (ECONOMIN_SP) and enter it into the
control.
2. Determine the IAQ minimum EconoMi$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 differential level so if the desired level to start IAQ control 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 differential 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$er+ can control up to 2 stages of power
exhaust. Power exhaust activation is done through configurable damper position set points. The first stage of power is
controlled by relay C4 on the EconoMi$er+ board. The activation 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).
XVI. 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
(evaporator) fan motor (IFM), compressor, and outdoor (condenser) fan motor (OFM) start. The OFM runs continuously

—45—

while the unit is in cooling. When the thermostat is satisfied,
C is deenergized 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$er+
When the thermostat calls for heating, terminal W1 is energized. The induced-draft motor is energized and the burner
ignition sequence begins. The indoor (evaporator) fan motor
(IFM) is energized 45 seconds after a flame is ignited. When
additional heat is needed, W2 is energized and the high-fire
solenoid on the main gas valve (MGV) is energized. When
the thermostat is satisfied and W1 is deenergized, the IFM
stops after a 45-second time-off delay.
C. Cooling, Units with EconoMi$er+

If the unit is in the unoccupied mode, then the control of the
temperature will depend on the unoccupied free cooling
configuration: no unoccupied cooling, unoccupied free cooling
with any mechanical cooling, or unoccupied free and
mechanical cooling. If free cooling is enabled, then the control will check if free cooling can be used. The EconoMi$er+
will then control to the leaving air temperature set point
plus 2 F for a Y1 command, or the leaving air temperature
set point for a Y1 and Y2 command. If mechanical cooling is
allowed to be used, then the control will then bring on additional stages of mechanical cooling if free cooling cannot satisfy the load.
If the EconoMi$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,

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.

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 linear relationship until the return air or space CO2 levels are
at or above the DAQHIGH limit. The damper position will be
at the ECONOMIN_SP set point.

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
changed in damper position will take up to 30 seconds to initiate. Damper movement from full closed to full open (or vice
versa) will take 21/2 minutes.

When the EconoMi$er+ is being used for free cooling and the
position exceeds the power exhaust set point, then the control 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

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 appropriate changeover command (switch, dry bulb, enthalpy curve,
differential dry bulb, or differential enthalpy), then the control 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 cooling 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$er+ damper
will be locked open at 100% or the maximum damper position set point.
To ensure that there is oil return, the compressors will
operate for at least 3 minutes. If, during this period, the leaving temperature drops below the set point by 5 F, then the
EconoMi$er+ dampers will be closed to 60% until the compressor 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 ventilation 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.

There is an unoccupied minimum damper position and an
occupied minimum damper position on the EconoMi$er+
controller. When the HVAC fan is off the outdoor air damper
will always be closed. When the fan is on and in the unoccupied mode, the outdoor air damper will be at the unoccupied
minimum position. When the fan is on (G call) and in the
occupied mode, the outdoor air damper will be at the occupied minimum position.
A jumper wire is factory-installed to force the unit into
occupied configuration whenever G or Y1 are closed. Without
the jumper wire, the unit will always be in unoccupied mode.
The 2 minimum position settings are also used in the IAQ
sequence of operation. See Indoor Air Quality Sensor on
page 18.
NOTE: The minimum position signal takes priority over the
maximum position signal. If the maximum damper position
is set below the minimum damper position, the EconoMi$er+
controller will maintain the actuator at minimum position.
Adjust the unoccupied minimum position to allow the minimum 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, perform the following procedure:
Calculate the appropriate supply-air temperature using the
following formula: (TO x OA) + (TR x RA) = TM

—46—

TO = Outdoor-Air Temperature
OA = Percent of Outdoor Air
TR = Return-Air Temperature
RA = Percent of Return Air
TM = Supply-Air Temperature

outer coil section 3 to 4 in. from the inner coil section.
See Fig. 39.
6. Use a water hose or other suitable equipment to flush
down between the 2 coil sections to remove dirt and
debris. Clean the outer surfaces with a stiff brush in
the normal manner.
7. Secure inner and outer coil rows together with a fieldsupplied fastener.
8. Reposition the outer coil section and remove the coil
corner post from between the top panel and center
post. Reinstall the coil corner post and replace all
screws.

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 with Economi$er+
When the room temperature calls for heat through terminal
W1, the indoor (evaporator) fan contactor (IFC) and heater
contactor no. 1 (HC1) are energized. On units equipped for
2 stages of heat, when additional heat is needed, W2 is energized and the high-fire solenoid on the main gas valve (MGV)
is energized. The economizer damper moves to the minimum
position. When the thermostat is satisfied, the damper
moves to the fully closed position.

VII. REFRIGERANT CHARGE
Amount of refrigerant charge is listed on unit nameplate
(also refer to Table 1). Compressor must run a minimum of
10 minutes before adjusting or checking charge.
Unit panels must be in place when unit is operating during
charging procedure.

B. Low-Charge Cooling
Using Cooling Charging Charts, Fig. 41-44, vary refrigerant
until the conditions of the appropriate chart are met. Note
the charging charts are different from type normally used.
Charts are based on charging the units to the correct superheat for the various operating conditions. Accurate pressure
gage and temperature sensing device are required. Do not
use pocket type thermometers for measuring surface temperatures as they are not designed for this type of measurement. Connect the pressure gage to the service port on the
suction line. Mount the temperature sensing device on the
suction line and insulate it so that outdoor ambient temperature does not affect the reading. Indoor-air cfm must be
within the normal operating range of the unit.
C. To Use Cooling Charging Chart
Take the outdoor ambient temperature and read the suction
pressure gage. Refer to 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.

CAUTION: If the IGC must be replaced, be sure to ground
yourself 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.

REMEDY
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.
Ensure unit is fired on rate and temperature rise is correct.
Ensure unit’s external static pressure is within application guidelines.
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.
Reset unit. If problem persists, replace control board.
Check operation of indoor (evaporator) fan motor and that supply-air
temperature rise agrees with range on unit nameplate information.
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.
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 switch will automatically reset, but IGC will continue to lockout unit.
Check gas valve operation. Ensure that induced-draft blower wheel is properly secured to motor shaft.
Reset unit at unit disconnect.
If error code is not cleared by resetting unit power, replace the IGC.
Fault code will automatically reset after one hour. Can be immediately
reset by resetting unit power supply.

IMPORTANT: Refer to Table 42 — Heating Service Analysis for additional
troubleshooting analysis.
