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 SIZEÐSELECT 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).

e.ON/OFF DELAYÐSELECT 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
(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.

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 perfor- mance is required, or if system enhancements such as super dehumidify are not needed.
(1.) AUX HEAT
(2.) AC/HP
(4.) AC/HP CFM
(6.) CONTINUOUS
i.COMFORT OPTIONSÐSUPER DEHUMIDIFY (See Quick Reference Guide)
The Super Dehumidify option is possible when this unit is installed with a field supplied Thermidistat™ control (Super Dehumidify does not require an outdoor temperature sensor). The following configuration is recommended for maximum cooling/dehumidifying comfort: This configuration will im- prove the comfort provided by the air conditioning system if more humidity removal is desired. While providing this im- proved comfort, the system will operate efficiently, but not at the published HSPF or ARI SEER efficiency.
The following system configuration is recommended for maxi- mum heating and cooling/dehumidifying comfort (See Fig. 11).
