DI1
Configuration of Digital Input 1.
Default:
None
(None):
No function is associated with an input.
(RemNSB):
Remote Night Setback (NSB) via a time clock input, an
occupancy sensor, or from a voltage-free contact.
Contact open = Occupied; contact closed = Unoccupied.
(RemOVR):
Temporary occupancy request via a remote input. This
override function is controlled by a manual remote occupancy
override. When enabled, this condition disables the override
capability of the thermostat controller.
(Filter):
A Filter alarm is displayed. This alarm can be connected to
a differential pressure switch that monitors a filter.
(Service):
A Service alarm is displayed on the thermostat controller
when the input is energized. Tie this input into the air conditioning
unit control card, which provides an alarm if a malfunction occurs.
(Fan lock):
A backlit flashing Fan lock alarm is displayed on the
thermostat controller when the input is not energized. This alarm is
used in conjunction with a local airflow sensor connected to the
input. The thermostat controller heating or cooling action is locked
out if no airflow is detected 10 seconds after the fan (Terminal G) is
energized. Contact open = no airflow; contact closed = airflow
present.
