• If the discharge air temperature is configured and DualMax control is enabled:
o As heating demand rises from 0-50%, the discharge air temperature shall be reset
upwards, to a maximum of 20 deg above zone temperature. The stages of heat shall be
enabled to maintain a discharge air temperature setpoint.
o As heating demand rises from 51-100%, the airflow setpoint shall reset from the
minHeatFlowStpt (A230) to the maxHeatFlowStpt (A229) flow.
o The duct coil shall control the VAV discharge air temperature to the setpoint. The duct coil
shall not directly control zone temperature.
