Unoccupied Cooling Setpoint: Setpoints have a range from 40.0°F to 115.0°F (4.44°C to
46.11°C). This cooling setpoint is used when the UCM is unoccupied. The unoccupied cooling
setpoint must be greater than or equal to the unoccupied heating setpoint plus 2.0°F (1.1°C).
Unoccupied Heating Setpoint: Setpoints have a range from 40.0°F to 115.0°F (4.44°C to
46.11°C). This heating setpoint is used when the UCM is unoccupied. The unoccupied cooling
setpoint must be greater than or equal to the unoccupied heating setpoint plus 2.0°F 1.1°C).
Occupied Offset: Setpoints have a range from 0.9°F to 45°F (-17.27°C to 7.22°C). If a zone
sensor thumbwheel setpoint is not being used, this setpoint are added and subtracted from the
Space Temperature Setpoint Default to determine the occupied heating and cooling setpoints.
Standby Offset: Setpoints have a range from 0.9°F to 45°F (-17.27°C to 7.22°C). If a zone sensor
thumbwheel setpoint is not being used, this setpoint are added and subtracted from the Space
Temperature Setpoint Default to determine the standby heating and cooling setpoints.
Space Temperature Setpoint Default: Setpoints have a range from 40.0°F to 115.0°F (4.44°C
to 46.11°C). If a zone sensor thumbwheel setpoint is not being used, this setpoint is used as the
UCM's active cooling setpoint during occupied times. The cooling setpoint must be greater
than or equal to the heating setpoint plus 2.0°F (1.1°C).
