-
Unocc Cooling: The unit operates in a cooling mode. Typically the cooling device operates at its limited max position with the outdoor air damper closed until the temperature drops below the unoccupied cooling setpoint for a period of time. The system then transitions to Satisfied.
-
Unocc Heating: The unit operates in a heating mode. Typically the heating device operates at its limited max position with the outdoor air damper closed until the temperature rises above the unoccupied heating setpoint for a period of time. The system then transitions to Satisfied.
-
Unocc Cntrl Not Req’d: The unit is in this mode if it is not in an unoccupied mode or warmup or cooldown are active.
-
Satisfied: The temperature has returned within the limits defined by the unoccupied temperature setpoints.
-
Temperature Unreliable: The monitored temperature is unreliable.
-
Low OA-T: The system enters this mode if Monitor OA During Unoccupied is TRUE, the outdoor air temperature is reliable and below the Low OA Temperature Setpoint and the zone temperature is within the band specified by the two unoccupied temperature setpoints. If the zone temperature drops below the unoccupied heating setpoint and cooldown mode is not active, the system transitions to Unocc Heating. If the zone temperature rises above the unoccupied cooling setpoint and warmup mode is not active, the system transitions to Unocc Cooling.
