d. COOLING MODE-SUPER DEHUMIDIFY OPERATION (SEE QUICK REFERENCE GUIDE) NOTE: Thermidistat™ is capable of providing Super Dehumidify operation mode and 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 (Occurs if outdoor temperature is below outdoor temperature change over setpoint.) (1.) Thermostat closes circuit R to W/W1—The unit delivers the selected gas heat airflow. The IGC will control 45 sec. on delay with no airflow and 45 sec. off delay. f. HEAT PUMP HEATING MODE (Occurs if outdoor temperature is above outdoor temperature change over setpoint.) (1.) Thermidistat™ closes circuit R to G and R to Y/Y2–The unit delivers selected heat pump heating airflow. g. HEATING MODE—SUPER COMFORT HEAT OPERATION NOTE: The Thermidistat™ is capable of providing Super Comfort Heat operation mode and must be configured as outlined in its installation instructions. The system must be installed with appropriate outdoor temperature sensor. Consult Thermidistat™ literature for configuration instructions. Consult sensor instructions for sensor installation details. If the outdoor temperature is in the range of 12° to 40° F, the Thermidistat™ closes circuit R to Y/Y2 and opens circuit R to G. If circuit R to G is closed (24-v.), the motor will deliver airflow at the full heating requested value. If circuit R to G is open (0-v.) for maximum heating comfort, the motor delivers reduced airflow to maximize the temperature and minimize the draft effect of the heated air leaving the unit. G.

The ICM motor uses the selected taps to modify its operation to a pre-programmed table of airflows. The unit must be configured to operate properly with system components with which it is installed. To successfully configure a basic system (see information printed on circuit board label located next to select pins), move the 6 select wires to the pins which match the components used. a. AUX HEAT kW/CFM—SELECT HEATER RANGE FOR SIZE OF ELECTRIC HEATER INSTALLED Installer must select the auxiliary heat airflow approved for 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 —7— 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 approximately 315 CFM per ton for higher normal heating air delivery temperature and prov...
