Prop.band Heat Temperature range over which all heater are modulated (Staged AP)
Prop.band humid Humidity range over which all humidifier stages are equally activated.
Prop.band Dehum Humidity range over which all dehumidification stages are equally
activated or chilled water valve modulates to full open.
Temp. I-time Integral action time constant used in the PID control loop
Humid. I-time Integral action time constant used in the PID control loop
Temp. D-time Derivative function used in PID control loop
Humid. D-time Derivative function used in PID control loop
Humid. Control Choose to enable or disable humidity control or control Humidification.
Reheat Control Choose to enable or disable reheat control or control reheat.
Dehum. Control Choose to enable or disable humidity control or control Dehumidification.
Free-cooling Control Choose to enable or disable Glycol Free Cooling
Free Cooling T/D Change over from DX to Economizer based on Return Air Temperature
and Entering Glycol Temperature. This represents the minimum difference
between the two measurements to allow for this feature to operate.
Free Cooling H/L Disables compressors in economization mode when the Entering Glycol
Temperatures reaches this set point or lower.
Damper switch delay Adjusts the time for the fan to turn on in damper applications.
Temp Control Allows for control by MAX or Average when multiple sensors are used.

Parameter Definition
System Type Identifies cooling type and number of stages
Control Mode This function is used in the test mode to be able to select manual operation and
activate devises manually from the test mode pages.
Restart Delay Delays the unit from starting until the time limit expires.
Network address Controller address to identify the unit in a BMS network.
Sensor mode Enables or disables the unit air temperature sensor from the averaging features in
a Co-Work network during standby periods. Also used for disabling sensor for
demonstrations.
Heater Min. On Sets the minimum demand required for the Reheat to begin operating.
Cool Min. On Sets the minimum demand required for the Cooling to begin operating
