Manual setpoint adjustment & EefCndTrg
The default configuration will reset a user-entered setpoint adjustment when the
room mode changes. To eliminate this reset, do the following:
- Set Comfort/Pre-Comfort to Economy (CmfPcfToEco) to "None"
- Set Comfort to Pre-Comfort (CmfToPcf) to "None"
These parameters are in the AF, Room operating mode determination
ROpModDtr. They are not BACnet objects, so ABT Site is required to access them.
