Mode1:
If SingleSPHeatDB (AV18) , SingleSPCoolDB (AV19) = 0 and ComSensorSpType (MSV16)
= SingleSp
The effective heat/cool setpoints (AV50) for the occupied and standby modes are derived from Occ-
CoolSP (AV40) and OccHeatSP (AV41) plus the absolute setpoint offset, calculated as the difference
between SingleSP and the mean of the OccHeatSP (AV41) and OccCoolSP (AV40) setpoints :
abs_setpoint_offset = SingleSP - (OccHeatSP (AV41) + OccCoolSP (AV40))/2
Occupied mode :
ActCoolSP (AV36) = OccCoolSP (AV40) + abs_setpoint_offset
ActHeatSP (AV37) = OccHeatSP (AV41) + abs_setpoint_offset
Standby mode :
ActCoolSP (AV36) = StandbyCoolSP (AV39) + abs_setpoint_offset
ActHeatSP (AV37) = StandbyHeatSP (AV42) + abs_setpoint_offset
Mode2:
If SingleSPHeatDB (AV18) < 0 or SingleSPCoolDB (AV19) > 0 and ComSensorSpType
(MSV16) = SingleSp
Occupied mode :
OccHeatSP (AV41) = SingleSP (AV17) + SingleSPHeatDB (AV18)
OccCoolSP (AV40) = SingleSP (AV17) + SingleSPCoolDB (AV19)
Standby mode :
abs_Stdby_setpoint_Offset = SingleSP – (StandbyCoolSP (AV39) + StandbyHeatSP (AV42))/2
ActCoolSP (AV36) = StandbyCoolSP (AV39) + abs_Stdby_setpoint_Offset
ActHeatSP (AV37) = StandbyHeatSP (AV42) + abs_Stdby_setpoint_Offset
ID Units Valid Range Default Value

SingleSPHeatDB (AV18)
This variable is used to set Heat Setpoint dead band for SingleSP Mangement (see SingleSP section
for more information).
ID Units Valid Range Default Value
Analog Value 18 Delta-Degrees-Celsius (∆°C) < 0 0 ∆°F
SingleSPCoolDB (AV19)
This variable is used to set Cool Setpoint dead band for SingleSP Mangement (see SingleSP section
for more information).
ID Units Valid Range Default Value
Analog Value 19 Delta-Degrees-Celsius (∆°C) > 0 0 ∆°F
PropHeat (AV20)
This variable is used to display the actual proportional heating signal. This variable can be used to
override the proportional heating control signal.
ID Units Valid Range Default Value
Analog Value 20 Percent (%) 0 to 100% 999%
Humidifier (AV21)
This variable is used to display the actual humidifier signal. This variable can be used to override the
humidifier control signal.
