RECEIVING AND INSTALLATION

Refer to unit Installation Instructions.

ICM FIOP PRE-START-UP

I. ELECTRICAL CONNECTIONS A. Control Voltage Connections

NOTE: Do not use any type of power-stealing thermostat, with-

out connecting the C (Common) terminal. Failure to follow this note could result in unit control problems.

Use no. 18 American Wire Gage (AWG) color-coded, insulated (35 C minimum) wires to make the control voltage connections between the thermostat and the unit. If the thermostat is located more than 100 ft from the unit (as measured along the control voltage wires), use no. 16 AWG color-coded, insulated (35 C minimum) wires.

B. Standard Connection

Remove knockout hole located in the heat section panel adjacent to the service access panel (See unit installation package). Remove the rubber grommet from the installer’s packet (included with unit) and install grommet in the knockout opening. Provide a drip loop before running wire through panel. Run the low-voltage leads from the thermostat, through the inlet hole, and into unit low-voltage splice box. Locate 18-gage wires leaving control box. These low-voltage connection leads can be identified by colors (See Fig. 2, 3, 4 or 5). Ensure the leads are long enough to be routed into the low-voltage splice box (located below right side of control box). Route leads through hole in bottom of control box and make low-voltage connections (See Fig. 2, 3, 4 or 5). Secure all cut wires, so that they do not interfere with operation of unit.

SPECIAL PROCEDURES FOR 208–V OPERATION

WARNING: Make sure that the power supply to the unit is switched OFF before making any wiring changes. With disconnect switch open, move yellow wire from transformer (3/16 in.) terminal marked 230 to terminal marked

200. This retaps transformer to primary voltage of 208-v. Electrical shock could cause serious injury or death.

i. COMFORT OPTIONS—SUPER DEHUMIDIFY (See Quick

Reference Guide) The Super Dehumidify option is possible when this unit is

installed with a field supplied Thermidistat™ control (SuperDehumidify does not require an outdoor temperature sensor). The following configuration is recommended for maximum cooling/dehumidifying comfort. This configuration will improve the comfort provided by the air conditioning system if more humidity removal is desired. While providing this improved comfort, the system will operate efficiently, but not at the published ARI SEER efficiency. During cool-to-dehumidify call, it provides maximum dehumidification by reducing airflow to a minimum. The actual super dehumidify command from Thermidistat™ control to the indoor unit is a “Y” signal without a “G” signal in addition to dehumidify signal. The indoor unit responds to this combination by reducing the airflow to a minimum. All other characteristics of cool to dehumidify are the same. The following system configuration is recommended for maximum cooling/dehumidifying comfort (See Fig. 8).

(1.) HEAT-Factory selected to match gas heat size of unit

installed.

(2.) AC/HP Size-Factory selected to match system size, please

verify.

(3.) SYSTEM TYPE-Factory selected on 583B system AC-

AIR CONDITIONER. (4.) AC/HP CFM ADJUST-Select NOM (Lo for 060). (5.) ON/OFF DELAY-Select ENH profile. (6.) CONTINUOUS FAN-Select desired fan speed when ther-

mostat is set to continuous fan. (7.) DEHUMIDIFY MODE-Remove J1 jumper to activate.

NOTE: J1 jumper should only be removed when a Thermidistat™, humidistat or capable zoning control is installed.

(8.) LOW VOLTAGE CONNECTIONS-Make connections as

shown in ELECTRICAL CONNECTIONS section. (9.) CONFIGURE THERMIDISTAT™-Follow Thermidis-

tat™ (or capable zoning system) installation instructions

for Super Dehumidify operation.

ACCESSORY INSTALLATION a. AUXILIARY TERMINALS

The AUX and HUM terminals on the Easy Select™ Board are tied directly to the G terminal, and provide a 24-v. signal whenever the G terminal is energized (See Fig. 6). During Super dehumidify mode, the G signal is not present and the auxiliary terminals are not energized. If the installation includes the use of this operating mode, do not use these terminals to control accessories. See Electronic Air Cleaner and Humidifier sections for further information.

b. ELECTRONIC AIR CLEANER CONNECTIONS

The AUX1 and AUX2 terminals are not always energized during blower operations, as described above. When using an electronic air cleaner with the unit, use Airflow Sensor P/N.

KEAAC0101AAA. The airflow sensor turns on electronic air cleaner when the blower is operating.

c. HUMIDIFIER/HUMIDISTAT CONNECTIONS

Easy Select™ Board terminals HUM1 and HUM2 are provided for direct connection to the low-voltage control of a humidifier through a standard humidistat (See Fig. 6). These terminals are energized with 24-v. when G thermostat signal is present (See Fig. 6 & 7). Alternately, the 24-v. signal may be sourced from the W and C on the 9 pin connector. When using a Thermidistat™ Control, Zone Perfect Plus or Comfort Zone II, the 24-v. signal may be sourced directly from the Thermidistat™ HUM terminal (See Fig. 6,7&8).

d. DEHUMIDIFY CAPABILITY WITH STANDARD

HUMIDISTAT CONNECTION Latent capacities for this unit are better than average systems. If increased latent capacity is an application requirement, the ICM board provides connection terminals for use of a standard humidistat. The unit will detect the humidistat contacts opening on increasing humidity and reduce its airflow to approximately 80 percent of nominal cooling mode airflow. This reduction will increase the system latent capacity until the humidity falls to a level which causes the humidistat to close its contacts. When the contacts close, the airflow will return to 100 percent of selected cooling airflow. To activate this mode, remove jumper J1 and wire in a standard humidistat (See Fig. 7).

e. DEHUMIDIFY AND SUPER DEHUMIDIFY

CAPABILITIES This model unit is capable of responding to a signal from indoor system control (Thermidistat™ or capable zoning control) to operate in comfort control modes such as Super Dehumidify Mode. Consult literature provided with indoor system control to determine if these operating modes are available, and to see control set up instructions. No special setup or wiring of unit is required.

(1.) If indoor temperature is above temperature set point and

humidity is below humidity set point, thermostat closes circuits R to G, R to Y/Y2 and R to O—The unit delivers single speed cooling airflow.

c. COOLING MODE-DEHUMIDIFICATION

(1.) If indoor temperature is above temperature set point and

humidity is above humidity set point, thermostat or Thermidistat™ closes circuits R to G, R to Y/Y2, R to O and humidistat or Thermidistat™ opens R to DH—The unit delivers airflow which is approximately 80 percent of the nominal cooling airflow to increase the latent capacity of the system.

d. COOLING MODE-SUPER DEHUMIDIFY OPERATION

(SEE QUICK REFERENCE GUIDE)

NOTE: The indoor control used, such as a Thermidistat™, must be capable of providing Super Dehumidify operation mode and control must be configured as outlined in its installation instructions. Consult indoor control literature to determine if control is capable of providing Super Dehumidify inputs and for configuration instruction.

(1.) If the indoor temperature is below the temperature set

point and the humidity is above the humidity set point, the Thermidistat™ closes circuit R to O, opens circuits R to DH and R to G, and closes circuit R to Y/Y2. If circuit R to G is closed (24-v.), the motor will deliver airflow at the full cooling or cooling plus dehumidify mode requested value. If circuit R to G is open (0–v.) for Super Dehumidify mode, the motor delivers reduced airflow to maximize the humidity removal of the system while minimizing over cooling.

e. GAS HEATING MODE

(1.) Thermostat closes circuit R to W/W1—The unit delivers

the selected gas heat airflow. The IGC will control a 45 sec. blower “On” delay and a 45 sec. “Off” delay.

E. Easy Select™—683B NOTE: Either the Bryant Thermidistat™ or Dual Fuel ther-

mostat is required for operation of the dual-fuel (683B) units. Be sure to follow the installation instructions supplied with the Thermidistat™. Either indoor temperature control must use an outdoor air sensor to properly control heating operation.

EASY SELECT™ CONFIGURATION TAPS FOR 683B

application with kW size heater installed. If no heater is installed, this step can be skipped. Each select pin is marked with a range of heaters for which airflow (also marked), is approved. For increased comfort, select the narrowest kW range matching the heater size, for example, 0–10 for 10–kW heater. This airflow must be greater than the minimum for CFM for electric heater application with the size system installed for safe and continuous operation. (See Tables 16, 17 & 18 for airflow delivery and minimum CFM.) Note that airflow marked is the

airflow which will be supplied in emergency heat mode and heating mode on air conditioners when electric heat is the primary heating source. In heat pump heating mode when electric heaters are energized, the ICM will run the higher of heat pump heating airflow and electric heater airflow to ensure safe heater operation. The factory selection is the largest heater range approved (See Fig. 11, A as indicated).

b. AC/HP SIZE—SELECT SYSTEM SIZE INSTALLED

The factory setting for air conditioner or heat pump size is the size which matches the model of packaged unit installed. Installer should verify air conditioner or heat pump size to ensure that airflow delivered falls within proper range for the size unit installed. This applies to all operational modes with the exception of electric heat modes (See Fig. 11, B as indicated).

c. SYSTEM TYPE—SELECT SYSTEM TYPE INSTALLED

The type of system will be factory selected (see below for details):

(1.) AC-Air conditioner (Factory Selected for 702B) (2.) HP-COMFORT—Heat Pump Comfort provides approxi-

mately 315 CFM per ton for higher normal heating air delivery temperature and provides approximately 350 CFM per ton cooling airflow for good humidity removal.

(3.) HP-EFF (Factory Selected for 602B)— Heat Pump Effi-

ciency provides same airflow for heating and cooling modes to increase overall HP efficiency; approximately 350 CFM per ton.

d. AC/HP CFM ADJUST—SELECT NOMINAL, LOW, OR

HIGH AIRFLOW The AC/HP CFM Adjust select is factory set to the High-Hi

(NOM for 060) tap. The CFM Adjust selections NOM/LO will regulate airflow supplied for all operational modes, except non-heat pump heating modes. HI provides 15 percent airflow over nominal unit size selected and LO provides 10 percent airflow below nominal unit size selected. CFM Adjust selection options are provided to adjust airflow supplied to meet individual installation needs for such things as noise, comfort, and humidity removal (See Fig. 11, D as indicated).

e. ON/OFF DELAY—SELECT DESIRED

TIME DELAY PROFILE Four motor operation delay profiles are provided to customize

and enhance system operation (See Fig. 11, E as indicated). Selection options are:

(1.) The standard 90 sec off delay (Factory Setting) at 100

percent airflow in cooling or heat pump heating mode.

(2.) A 30 sec cooling delay with no airflow/90 sec off delay at

100 percent airflow profile is used when it is desirable to allow system coils time to heat-up/cool-down in conjunction with the airflow in cooling or heat pump heating mode.

(3.) A no delay option used for servicing unit or when a

thermostat is utilized to perform delay functions.

(4.) ENH, enhanced selection, provides a 30 sec cooling on

delay with no airflow/ plus 150 sec at 70 percent airflow/ no off delay for added comfort. This will minimize cold blow in heat pump operation (602B only) and could enhance system efficiency.

f. CONTINUOUS FAN—SELECT DESIRED FAN SPEED

WHEN THERMOSTAT IS SET ON CONTINUOUS FAN (1.) LO speed—Factory setting, 50 percent cooling mode

airflow.

(2.) MED speed—Move connector to MED, 65 percent cooling

mode airflow.

(3.) HI speed—Move connector to HI, 100 percent cooling

mode airflow (See Fig. 11, F as indicated). g. LOW-VOLTAGE CIRCUIT FUSING AND REFERENCE

h. BASIC UNIT CONFIGURATION

The following basic configuration of the indoor motor will provide ARI rated performance of the System. This BASIC

CONFIGURATION should be used when the rated ARI performance is required, or if system enhancements such as super dehumidify are not needed.

(1.) AUX HEAT kW/CFM-Select the heater range for the size

of electric heater installed (skip this step if no heater is installed).

(2.) AC/HP SIZE-Factory selected to match system size in-

stalled, please verify.

(3.) SYSTEM TYPE-Factory selected AC (702B) or HP-EFF

(602B).

(4.) AC/HP CFM ADJUST-Select HIGH for 042 & 048, NOM

for 036 & 060, and LO for 024 & 030. (5.) ON/OFF DELAY-Select 0/90 profile. (6.) CONTINUOUS FAN-Select desired fan speed when ther-

mostat is set to continuous fan.

i. COMFORT OPTIONS—SUPER DEHUMIDIFY (See Quick

Reference Guide) The Super Dehumidify option is possible when this unit is

(1.) AUX HEAT kW/CFM-Select the narrowest heater range to

match size of electric heater installed (skip this step if no heater is installed).

(2.) AC/HP Size-Factory selected to match system size in-

stalled, please verify.

(3.) SYSTEM TYPE-Select system type HP-COMFORT (for

heat pump system) or AC (for air conditioner system). (4.) AC/HP CFM ADJUST-Select NOM (Lo for 060). (5.) ON/OFF DELAY-Select ENH profile. (6.) CONTINUOUS FAN-Select desired fan speed when ther-

mostat is set to continuous fan. (7.) DEHUMIDIFY MODE-Remove J1 jumper to activate. (8.) LOW VOLTAGE CONNECTIONS-Make connections as

shown in ELECTRICAL CONNECTIONS section. (9.) CONFIGURE THERMIDISTAT™ (or capable zoning

system)-Following its installation instructions for Super

Dehumidify and Super Comfort Heat operation.

Page 9

This configuration provides the following comfort enhancements:

(a.) A 30 sec blower on delay with 150 sec at 70 percent

airflow to allow the indoor coil to warm up or cool down before the blower is asked to deliver 100 percent airflow reducing the cold blow sensation at start up in heating and allowing the indoor coil to more quickly reach wet coil operating conditions in cooling.

(b.) A no blower off delay eliminates cold blow which may

be associated with running the blower after shut down of the compressor and avoids re-evaporation of condensed moisture after cooling/dehumidifying operation.

(c.) Lower airflow while the compressor is running to

reduce draft effects and increase heating air temperature and improved humidity control during cooling

operation. ACCESSORY INSTALLATION a. ACCESSORY ELECTRIC HEATERS

Electric heaters may be installed with the 702B & 602B units per instructions supplied with electric heater package. See unit rating plate for factory-approved electric heater kits.

b. AUXILIARY TERMINALS

The AUX and HUM terminals on the Easy Select™ Board are tied directly to the G terminal, and provide a 24-v. signal whenever the G terminal is energized (See Fig. 12). During Super dehumidify mode, the G signal is not present and the auxiliary terminals are not energized. If the installation includes the use of the operating mode, do not use these terminals to control accessories. See Electronic Air Cleaner and Humidifier sections for further information.

c. ELECTRONIC AIR CLEANER CONNECTIONS

The AUX1 and AUX2 terminals are not always energized during blower operations, as described above. When using an electronic air cleaner with the unit, use Airflow Sensor P/N KEAAC0101AAA. The airflow sensor turns on electronic air cleaner when the blower is operating.

d. HUMIDIFIER/HUMIDISTAT CONNECTIONS

Easy Select™ Board terminals HUM1 and HUM2 are provided for direct connection to the low-voltage control of a humidifier through a standard humidistat (See Fig. 12). These terminals are energized with 24-v. when G thermostat signal is present. (See Fig. 11, 12 & 13). Alternately, the 24-v. signal may be sourced from the W and C circuit board connections. When using a Thermidistat™ Control, Zone Perfect Plus or Comfort Zone II, the 24-v. signal may be sourced directly from the Thermidistat™ HUM terminal.

e. DEHUMIDIFY CAPABILITY WITH STANDARD

HUMIDISTAT CONNECTION Latent capacities for these units are better than average systems.

If increased latent capacity is an application requirement, the circuit board provides connection terminals for use of a

standard humidistat. The unit will detect the humidistat contacts opening on increasing humidity and reduce its airflow to approximately 80 percent of nominal cooling mode airflow. This reduction will increase the system latent capacity until the humidity falls to a level which causes the humidistat to close its contacts. When the contacts close, the airflow will return to 100 percent of selected cooling airflow. To activate this mode, remove jumper J1 and wire in a standard humidistat ( See Fig.

13).

f. DEHUMIDIFY AND SUPER DEHUMIDIFY CAPABILITIES

these models are capable of responding to a signal from indoor system control (thermostat, Thermidistat™, zoning control) to operate in comfort control modes such as Super Dehumidify Mode. Consult literature provided with indoor system control to determine if these operating modes are available, and to see control set up instructions. No special setup or wiring of unit is required.

H. 702B & 602B Sequence Of Operation

a. CONTINUOUS FAN

(1.) Thermostat closes circuit R to G—The Blower runs at

continuous fan airflow.

b. COOLING MODE-LOW HUMIDITY

(1.) If indoor temperature is above temperature set point and

humidity is below humidity set point, thermostat closes circuits R to G, R to Y/Y2 and R to O—The unit delivers cooling airflow.

c. COOLING MODE-DEHUMIDIFICATION

(1.) If indoor temperature is above temperature set point and

humidity is above humidity set point, thermostat or Thermidistat™ closes circuits R to G, R to O, and R to Y/Y2 and humidistat or Thermidistat™ opens R to DH—The unit delivers airflow which is approximately 80 percent of the nominal cooling airflow to increase the latent capacity of the system.

d. COOLING MODE-SUPER DEHUMIDIFY OPERATION (see

quick reference guide)

(1.) If the indoor temperature is below the temperature set

point and the humidity is above the humidity set point, the Thermidistat™ closes circuit R to O, opens circuits R to DH and R to G, and cycles circuit R to Y/Y2. If circuit R to G is closed (24-v.), the motor will deliver airflow at the full cooling or cooling plus dehumidify mode requested

value. If circuit R to G is open (0–v.) for super dehumidify mode, the motor delivers reduced airflow to maximize the humidity removal of the system while minimizing over cooling.

e. ELECTRIC HEATING MODE

(1.) Thermostat closes circuit R to W/W1, or W2—The unit

delivers the selected electric heat airflow. There are no on or off delays.

f. HEAT PUMP HEATING MODE (602B only)

(1.) Thermostat closes circuits R to G and R to Y/Y2—The unit

delivers selected heat pump heating airflow.

g. HEAT PUMP HEATING WITH AUXILIARY

ELECTRIC HEAT (602B only) (1.) Thermostat closes circuits R to G, R to Y/Y2 and R to

W/W1 or W2 (and R to O in the case of defrost).

In the event that electric heating is called for by the thermostat while the heat pump is also operating in either heating or defrost modes, the motor will modify its airflow output, if necessary, to provide an airflow which is defined as safe for the operation of the electric heater during heat pump operation. That airflow is the greater of the heat pump heating airflow and the electric heater only airflow.

h. HEATING MODE—SUPER COMFORT HEAT OPERA-

TION

NOTE: The indoor control used, such as a Thermidistat™, must be capable of providing Super Comfort Heat operation mode and control must be configured as outlined in its installation instructions. The system must be installed with appropriate outdoor temperature sensor. Consult indoor control literature to determine if control is capable and for configuration instructions. Consult indoor control instructions and sensor instructions for sensor installation details.

ICM FIOP START-UP

ICM General Start Up

CHECKING AND ADJUSTING REFRIGERANT CHARGE The refrigerant system is fully charged with Puron® (R-410A) refrigerant, and is tested and factory sealed.

NOTE: Adjustment of the refrigerant charge is not required UNLESS the unit is suspected of not having the proper R-410A charge.

The charging label and the tables shown refer to system temperatures and pressures. The temperatures and pressures are calculated at rated airflow. When charging unit, set to rated airflow. A refrigerant charging chart label is attached to the outside of the compressor access door. The chart includes the required suction line temperature at given suction line pressures and outdoor ambients. An accurate superheat, thermocouple- or thermistor-type thermometer, and gage manifold are required when using the superheat charging method for evaluating the unit charge. Do not

use mercury or small dial-type thermometers because they are not adequate for this type of measurement

IMPORTANT: When evaluating the refrigerant charge, an indicated adjustment to the specified factory charge must always be very minimal. If a substantial adjustment is indicated, an abnormal condition exists somewhere in the cooling system, such as insufficient airflow across either one or both coils.
