Point Name/Description
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.
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.
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.
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.
Supply Air Temperature – Displays the current supply air temperature.
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.
Space Relative Humidity – Displays the current value of relative humidity sensor, if
present.
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 > Space Relative Humidity.
