Description
Identifies the controller on the FLN trunk.
Identification number of the program running in the
controller.
Compensates for deviations between the value of
ROOM TEMP and the actual room temperature.
This corrected value is displayed in CTL TEMP.
RMTMP OFFSET + ROOM TEMP = CTL TEMP
Actual reading from the room temperature sensor.
Current mode of operation for applications that can
be in either a heating mode or a cooling mode.
The temperature setpoint in degrees that the
controller maintains during day periods in cooling
mode if a room temperature sensor setpoint dial is
not present or is not used. See STPT DIAL.
The temperature setpoint in degrees that the
controller maintains during the night periods in
cooling mode.
The temperature setpoint in degrees that the
controller maintains during day periods in heating
mode if a room temperature sensor setpoint dial is
not present or is not used. See STPT DIAL.
The temperature setpoint in degrees that the
controller maintains during the night periods in
heating mode.
The minimum temperature setpoint in degrees that
the controller can use from the setpoint dial. This
overrides any temperature setpoint from the
setpoint dial that falls below this minimum.
