6030 Remote Setback
Time Delay from
Occupied to
Unoccupied
0 to 30 minutes (in 5 minute
increments)
0 minutes Commercial Yes Remote Setback requires an EIM (Equipment
Interface Module).
The Remote Setback Time Delay forces the
thermostat to wait before it switches from
Occupied to Standby temperature settings.
When set to 0 minutes, the thermostat will
switch from Occupied to Standby temperature
settings immediately when the room is
unoccupied.
6040 Remote Setback -
Standby Cool
Setpoint
72° F to 90° F
85° 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.

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.
