THIS SCREEN ALLOWS THE USER TO ENABLE THE HEATER TO PROVIDE REHEAT IN

ADDITION TO HOT GAS REHEAT

This screen appears if hot gas reheat and a heating option was provided (except

heat pump).

Setting the heater parameter to enable allows the heating option to provide

additional reheat beyond what the hot gas reheat can provide. This would

typically only be used if the supply air temperature is too cold.

Heater Reheat 2

Will heater be used for reheat

along with hot gas?

Heater: Disable

THIS SCREEN DISPLAYS WHEN EACH COMPRESSOR IN A SINGLE OR DUAL STAGE DX

UNIT WILL ENGAGE/DISENGAGE.

This screen only appears if DX cooling was provided with the unit.

Each compressor will engage and disengage based upon the percentage of

cooling capacity the controller needs.

Compressor Staging

Stage1: ON @ 50% OFF 0%

Stage2: ON @ 100% OFF 50%

THIS SCREEN ALLOWS ADJUSTMENT OF THE HEATING PI CONTROL LOOP.

This screen only appears if heating option was provided with the unit.

The controller utilizes a PI loop control for heating. This allows for less sporadic

changes in supply temperature, resulting in a smooth reaction to changing

conditions. To speed up reaction time, decrease the integration time. For slower

reaction time, increase the integration time. When making adjustments, make

them in small increments and test the system to determine if the new setting is

adequate prior to further adjustment. The band is the range that the integration

will occur between. The off delay allows the heating output to temporarily

overshoot the setpoint without dropping the call for heat to prevent unwanted

cycling.

Integration: 300s

Band: 60°F

Off Delay: 60s

THIS SCREEN ALLOWS THE USER TO ENABLE THE HEATER FOR REHEAT PURPOSES.

This screen appears if a heating option was provided and the unit does NOT have

hot gas reheat OR a heat pump.

If it is desired that the heater be used to reheat the air off of the cooling coil when in

dehumidification, adjust this screen so the heater is ENABLED for reheat.

Heater Reheat

Will heater be used for reheat

during dehumidification?

Reheat: Disable

THIS SCREEN DISPLAYS THE COMPRESSOR MINIMUM ON AND OFF TIMES.

This screen only appears if DX cooling was provided with the unit.

The compressor minimum ON/OFF times prevents short cycling of the

compressors.

Compressor Timers

Minimum ON: 30s

Minimum OFF: 180s

Between Stages: 30s
