Occupied Heating 2

– Dark Blue

The space temperature must be less than the Occupied Heating 2 setpoint to

generate a low space temperature alarm. We recommend that this value be set no

less than 0.5°F below the Occupied Heating 1 setpoint.

68°F

67°F 66°F 64°F

Occupied Cooling 1

– Yellow

The space temperature must be greater than the Occupied Cooling 1 setpoint for

the VVT Master to consider the zone a cooling caller in a linked system. In a single-

zone application, the cooling requirement begins as soon as the space

temperature exceeds the Occupied Cooling setpoint. We recommend that the

Occupied Cooling 1

value be set no less than 0.5°F above the Occupied Cooling

setpoint.

75°F

76°F 77°F 79°F

Occupied Cooling 2

– Orange

The space temperature must be greater than the Occupied Cooling 2 setpoint to

generate a high space temperature alarm. We recommend that this value be set

no less than 0.5°F above the Occupied Cooling 1 setpoint.

– Light Blue

The space temperature must be less than the Unoccupied Heating 1 setpoint for the VVT

Master to consider the zone an unoccupied heating caller in a linked system. In a single-zone

application, the unoccupied heating requirement begins as soon as the space temperature falls
