Unoccupied Heating 2 – Dark Blue
The space temperature must be less than the Unoccupied Heating 2 setpoint to
generate an unoccupied low space temperature alarm. We recommend that this value
be set no less than 0.5 °F (.27 °C) below the Unoccupied Heating 1 setpoint.
Unoccupied Cooling 1 – Yellow
The space temperature must be greater than the Unoccupied Cooling 1 setpoint for the
VVT Master to consider the zone an unoccupied cooling caller in a linked system. In a
single-zone application, the unoccupied cooling requirement begins as soon as the
space temperature exceeds the Unoccupied Cooling setpoint. We recommend that the
Unoccupied Cooling 1 value be set no less than 0.5 °F (.27 °C) above the
Unoccupied Cooling setpoint.
Unoccupied Cooling 2 – Orange
The space temperature must be greater than the Unoccupied Cooling 2 setpoint to
generate an unoccupied high space temperature alarm. We recommend that this value
be set no less than 0.5 °F (.27 °C) above the Unoccupied Cooling 1 setpoint.
Point Name/Description
Heating Capacity – Used for Optimal Start, this is the rate at which the space
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.
