automatically adjust the ramp rate based on outdoor
conditions. This allows the thermostat to save energy by
starting recovery at the optimum time as outdoor conditions
change.
NOTE: The thermostat uses an adjustable ramp rate
when the thermostat is setup for commercial. This
allows the thermostat to recover on time during
changing conditions (occupancy changes, tem-
perature overrides, load conditions, opening/clos-
ing of doors etc) which are common in
commercial applications.

Custom Names
The thermostat location (name) can be displayed on the home
screen. See the name “OFFICE” in Fig. 298 and 299. This is
useful when multiple thermostats are mounted in a manager’s
office or equipment room, to quickly identify which thermostat
is in control of a specific zone or area.

Remote Setback
The thermostat allows you to do REMOTE SETBACK when set
up for commercial use. This feature requires an occupancy
sensor connected to the S1, S2, S3, or S4 terminals at the
EIM.
During occupied periods, the 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 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.
A Remote Setback Time Delay (ISU 6030) can be set to force
the thermostat to wait before it switches from occupied settings
to the standby settings. This allows the room to stay
comfortable if the room is unoccupied for a short period of
time. When set to 0 minutes, the thermostat will switch from
occupied settings to the standby settings immediately when
the room is unoccupied.
