Introduction (cont’d)
General Sequence
of Operation
When the unit is called to operate, the main blower will run continuously in
occupied mode and intermittently in unoccupied mode. The unit operates
based on four Discharge Air Temperature Setpoints listed below.
1. Standard (Neutral) Heating Discharge Air Temperature Setpoint
2. Space Heating Discharge Air Temperature Setpoint
3. Standard (Neutral) Cooling Discharge Air Temperature Setpoint
4. Space Cooling Discharge Air Temperature Setpoint
The heating and cooling equipment will cycle to maintain the active discharge
air temperature setpoint for occupied and unoccupied modes. Heating and
cooling may be locked out of operation based upon outdoor air temperature
and enthalpy conditions.
If equipped with reheat, the control will also activate the dehumidication circuit
to maintain a neutral discharge air temperature setpoint and related dewpoint
based upon outdoor air and space conditions.
