UNIT FEATURES CONTINUED

Unit Configuration

– There are many different

configuration possibilities, through both dipswitches

and the digital keypad, that allow you to configure

the unit for your exact application. See section on

unit configuration for more details. Following are the

configuration selections that have not previouslybeen

mentioned:

Indoor Temperature Sensor Biasing

– Optimize

the room temperature sensor reading to your exact

application (one for cooling and another for heating).

Emergency Heat (for Heat Pump Only)

– Disable

the compressor during heating mode operation (heat

only with Electric Heat).

unit can be configured to display the room

temperature OR setpoint only, during heating and

cooling modes. See section on unit configuration for

more details.

Limit the Setpoint Range

-- The unit can be

configured to limit the controlling setpoint range. The

display will always show the complete setpoint range,

but the controlling setpoint will be limited to the

configuredminimumandmaximumsetpointselected.

See section on unit configuration for more details.

Energy Management

– Sometimes known as

Front Desk Control,

an input is provided so that the

unit can be manually disabled from a different

location. If the unit detects 24vac on this input, it will

automatically turn itself off. If no voltage is detected

on the input, the unit will run normally.

Wall Thermostat Control

– A wired wall

thermostat can be connected to the unit. If it is, the

unit must be configured to disable the keypad. See

section on wired inputs and unit configuration for

more details.
