COOLING OPERATION

Zone Sensor Control

If a zone sensor controls the unit, the unit controller shall maintain the zone temperature 

setpoint. This setpoint is user selectable at the user interface.

When a zone sensor is used for control, the unit controller will monitor the temperature 

within the space and control the unit accordingly. A closed-loop staging algorithm is used 

to stage compressors up and down as required to maintain the desired zone temperature 

setpoint. If the unit is equipped with an economizer, outside air conditions are continu

-

ously monitored by the control to determine if conditions are suitable for economizing. If 

conditions are suitable for economizing, the unit controller will modulate the OA damper in 

addition to staging compressors up and down to maintain the zone temperature setpoint.

HEATING OPERATION

Zone Sensor Control

If a zone sensor controls the unit, the unit controller shall maintain all zone temperature 

setpoints. These setpoints are user selectable at the user interface.

When a zone sensor is used for control, the unit controller will monitor the temperature 

within the space and control the unit accordingly. A closed-loop staging algorithm is used 

to stage heating steps up and down as required to maintain the desired zone temperature 

setpoint. If the unit is equipped with an economizer, outside air conditions are continu

-

ously monitored by the control to determine if conditions are suitable for economizing. If 

conditions are suitable for economizing, the unit controller will modulate the OA damper in 

addition to staging heating steps up and down to maintain the zone temperature setpoint.
