Setpoint
50° F to 70° F
64° F Commercial Yes Remote Setback requires an EIM
(Equipment Interface Module).
During occupied periods, the occupancy
sensor tells the thermostat to go to
STANDBY (setback settings) when no one
is in the room. If someone is in the room,
then it follows the settings of the occupied
period. The occupancy sensor is ignored
during unoccupied periods.
If the thermostat is setup for non-
programmable, the occupancy sensor tells
the thermostat to go to STANDBY settings
when no one is in the room. If someone is
in the room, then it follows the settings set
by the user.
