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.

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.

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.

The remote setback feature only works in the non-

programmable mode.

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 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.

There are three temperature override options:

— Hold Temperature Until

— Override, and 

— Holiday.

HOLD TEMPERATURE UNTIL
Holds the temperature temporarily until the time set by the 

user, or the next scheduled period time.

1. Press the Up or Down arrow next to the temperature to 

adjust. The Hold Until time appears on the screen. The 

time defaults to the next scheduled period start time

2. Press NEXT to adjust the time for the thermostat to 

resume schedule.

NOTE: The installer setup can limit the length of time 

for an override to 1, 2, 3, or 4 hours beyond the 

current time.

3. Press DONE or wait 5 seconds.

4. Press CANCEL or SCHEDULE to cancel “Hold Tempera-

ture Until” and resume the schedule.

OVERRIDE
Changes temperature setting until the next period takes effect. 

For use during Unoccupied periods.

1. Press OVERRIDE. The settings change by default to the 

next Occupied period.

NOTE: Changes are limited to those allowed by the 

lockout level.

2. Press Up or Down arrow to change the override temper-

ature, and NEXT to adjust override time.

HOLIDAY
Changes temperature setting for a designated number of days. 

Press MORE and then HOLIDAY. The screen shows “Hold 

Until 1 DAYS”.

1. Press Up or Down arrow to change the temperature 

desired for the thermostat to override the schedule.

2. Press NEXT to change the desired days for the duration 

of the holiday.

3. To cancel the Holiday Override early, press CANCEL.

When the thermostat is running the fan, the fan blade symbol 

appears next to FAN to indicate the thermostat has the fan 

on.

NOTE: If the thermostat is not controlling the fan—typical for 

many gas, forced-air heating systems—the fan blade 

symbol 

 will not appear even though the fan may 

be running.

Not all thermostat models require batteries. If the thermostat 

has batteries, a low battery warning (see Fig. 38) flashes on 

the main screen for approximately 30 days.

NOTE:

—

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.
