Setpoints
The Setpoints Configuration subsection contains the heating and cooling setpoints for the occupied,
standby and unoccupied modes.
Figure 38: Setpoints configuration subsection
Parameter
Description
Unoocupied
The limits between which the temperature is to be maintained by the controller when
it is in Unoccupied mode. If the temperature passes these limits, the system reacts to
bring the temperature back within these limits. In Unoccupied mode, the space
temperature is usually allowed a larger amount of variance than in Occupied mode,
thereby lowering operating costs.
Occupied
The limits between which the temperature is to be maintained by the controller when
it is in Occupied mode. This temperature range should be comfortable to building
occupants.
Standby
The limits between which the temperature is to be maintained by the controller when
it is in Standby mode. In Standby mode, the temperature is usually allowed a larger
amount of variance than in Occupied mode. Still, it is maintained at a value close
enough to the occupied setpoints so that it can be varied quickly for occupancy.
Freeze protection
The limit at which the system is maintained to prevent freezing conditions.
HVAC Scaling
The HVAC Scaling subsection contains cooling and heating load values for fully open and fully closed
valves.
