Special Programmable Mode Functions
Installer Setup 160 allows the thermostat to be configured for
either a mode with a programmable 7 day schedule or as a
non-programmable thermostat.
Preoccupancy purge (ISU 185)
This feature is available only when the thermostat is configured
as a programmable schedule and when a fan is used. The fan
will run 1-3 hours before the occupied schedule starting time to
circulate air.
Override Button, Temporary Override (Duration Limit ISU
535)
While in the programmable schedule mode, an override button
is available to perform temporary override control. The default
override time can be configured through ISU 535. Lockout
configuration via ISU 670 can provide restrictions on access to
setpoint changes, system changes, and schedule changes.
No remote setback
The remote setback feature only works in the non-
programmable mode.
Special Non-Programmable Mode Functions
Override (Optional)
The override feature is optional in the non-programmable
mode. The override can be configured through ISU 342. When
the override is activated in the non-programmable mode it will
temporarily override to a new setpoint until the end time
expires.
Remote Setback
Remote Setback is available (ISU 340). Occupancy sensors,
manual time clock inputs, and DDC night setback can be used
to provide inputs to setback the thermostat. Unoccupied
heating (ISU 343) and unoccupied cooling (ISU 346) setpoints
are available to configure the setback setpoints.

— Hold Temperature Until

many gas, forced-air heating systems—the fan blade
symbol will not appear even though the fan may
be running.
— If batteries are not replaced when the Low Battery
warning is flashing, the LO batt screen displays
continuously and the thermostat stops operating
until batteries are replaced.
— The thermostat has a low battery indicator.
However, it is recommended that the batteries be
replaced once each year. Do this to prevent
leakage and prevent the thermostat and HVAC
system from shutting down due to lack of
thermostat battery power.
