Point Name/Description
Default/Range
Power Fail Restart Delay
– How long the controller delays normal operation after the
power is restored. This is typically used to prevent excessive demand when recovering
from a power failure. Applies to Series Fan start delay when system mode transitions
from unoccupied to occupied. A delay of no greater than 120 seconds is recommended
for Series Fan applications.

60 seconds
0 to 600 secs
Occupancy Schedules
– If
Enabled
, the controller stores and follows a schedule sent
over the network or programmed locally through a touchscreen or Field Assistant. If
Disabled
, the controller occupancy is controlled from the
BAS On/Off
or
System
Occupancy
network point.

Occ Override Delay
– The amount of time the controller remains occupied after the
remote occupancy switch returns to the unoccupied position.

R:
15 minutes
0 to 240 minutes
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

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.

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
