Setpoints
The
Setpoints Configuration
subsection contains the heating and cooling setpoints for the occupied,
standby and unoccupied modes.
Figure38: 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.
Figure39: HVAC Scaling Subsection
Parameter Description
Minimum cooling valve Input the cooling load value for 0% cooling valve opening.
Maximum cooling valve Input the cooling load value for 100% cooling valve opening.
Minimum heating valve Input the heating load value for 0% heating valve opening.
Maximum heating valve Input the heating load value for 100% heating valve opening.
Minimum electric heater Input the heating load value for 0% electric heater.
Maximum electric heater Input the heating load value for 100% electric heater.
