Issue:
On the LCI-R DAC Voyager where does the Morning Warm Up MWU initiate and terminate setpoints come from?
Resolution:
The Default Occupied Heating Setpoint is the MWU terminate setpoint and the MWU initiate is 1.5F below this point.
Notes:
When an LCI (Lontalk Communication Interface) is installed on a Voyager Commercial VAV unit, the morning Warmup (MWU) setpoint located on the RTAM board is ignored. The Morning Warmup and Daytime Warmup setpoints come from the higher priority LCI-R DAC.
The MWU terminate setpoint is identified as NCI (Network Configuration Input) nciSetpoints.occupied heat. The default setpoint is 71F. The MWU initiate setpoint is nciSetpoints.occupied heat - 1.5F.
The DWU initiate setpoint is NCIDaytime (default 69F) and the DWU terminate setpoint is NCIDaytimeTerm (default 72F).
