The ASHRAE Cycle selections create specific Generator and Output Controllers to control the Mixed Air Damper.
ASHRAE Cycles I, II, and W require a Discharge Air Temperature Input to interface to the damper control logic. This input is created if the Discharge Air Sensor was not selected under the Sensors (UV) selection. A DATLL-SP (Discharge Air Low Limit Setpoint) Network Input is also created for the Supervisory system interface. ASHRAE Cycles II and W also create a Damper Minimum Position Setpoint as a Network Input for the Supervisory system.
ASHRAE Cycle III requires a Mixed Air Temperature Input to interface to the damper control logic. This input is created if the Mixed Air Sensor was not selected under the Sensors (UV) selection. Mixed Air Temperature and Damper Minimum Position Setpoints are also created as Network Inputs for the Supervisory system.
The selection options for ASHRAE Cycle Control are:
ASHRAE Cycle I
ASHRAE Cycle II
ASHRAE Cycle III
ASHRAE Cycle W
