Appendix A: VAV Zone Controller Points/Properties
Point Name/Description
Default/Range
Occupancy Schedules
– If
Enabled
, the controller stores and follows a schedule sent over
the network or programmed locally through a BAC
view
device or Field Assistant. If
Disabled
, the controller occupancy is controlled from the
BAS On/Off
or
System Occupancy
network point.

T55 Override Duration
– The amount of time that the controller runs in the occupied mode
when a user presses the T55 sensor's override button for 1 to 10 seconds.
Pushbutton
Override
must be set to
Enable
.

Local Sensor Calibration
Space Temperature
– The current space temperature.
R:
-56 to 245°F
(-48.9 to 118.3°C)
Space Temp Calibration
– A calibration offset value to allow the local space temperature
sensor to be adjusted to match a calibrated standard measuring the temperature in the
same location.
D:
R:
0∆°F/∆°C
-
9.9 to 10∆°F
(-
5.5 to 5.5∆°C)
Supply Air Temperature
– Displays the current supply air temperature.
R:
-56 to 245°F
(-48.9 to 118.3°C)
Supply Air Temp Calibration
– A calibration offset value to allow the supply air
temperature sensor to be adjusted to match a calibrated standard measuring the
temperature in the same location.
D:
R:
0∆°F/∆°C
-
9.9 to 10∆°F
(-
5.5 to 5.5∆°C)
Space Relative Humidity –
Displays the current value of relative humidity sensor, if
present.
R:
0 to 100%
Relative Humidity Calibration
– You can enter a calibration offset for the relative humidity.
The offset is added to or subtracted from the controller's RH input value, and the
calculated value is shown in the
Status
