Unoccupied Heating 1 – Light Blue
The space temperature must be less than this value for the VVT Master to consider the
zone a heating caller. The zone remains a heating caller until the space temperature
rises above the Unoccupied Heating setpoint. We recommend that this value be set no
lower than .5°F below the Unoccupied Heating
Unoccupied Heating 2
– Dark Blue
The space temperature must be less than this value before a low space temperature
alarm is generated.
Unoccupied Cooling 1 – Yellow
The space temperature must be greater than this value for the VVT Master to consider
the zone a cooling caller. The zone remains a cooling caller until the space temperature
drops below the Unoccupied Cooling setpoint. We recommend that this value be set no
lower than .5°F above the Unoccupied Cooling
Unoccupied Cooling 2
– Orange
The space temperature must be greater than this value before a high space
temperature alarm is generated.
Point Name/Description
Heating Capacity
– Used for Optimal Start, this is the rate at which the zone
temperature changes when the heating system runs at full capacity to maintain
designed occupied heating setpoint.
Heating Design Temp
– The geographically-based outdoor air temperature at which the
heating system must run constantly to maintain comfort. This information is available
in ASHRAE publications and most design references.
