Service Indicator
The wrench symbol is displayed when there is a tempera-
ture sensor error or condensate overflow error. It indi-
cates there is an open or a short connection to the sensor
switch. When this occurs, the thermostat will disable all
outputs and illuminate the wrench symbol. A service
technician should be called to determine the cause of the
error.
Saving Changes
As you navigate your thermostat, be aware of the thermostat’s
save and exit protocol:
•
The thermostat automatically saves all the changes you
make, as you make them.
•
When you are in the SYSTEM or FAN menus:
– If you push a button that is not applicable to the current
menu, all changes are saved and the thermostat goes to
the menu associated with the button that was pushed.
– If the thermostat is idle for five seconds, the thermostat
times out, saves all changes, and returns to the thermo-
stat’s default display.
•
When you are in the PROGRAM menu:
– If you push a button that is not applicable to the current
menu, nothing happens (your programming is not inter-
rupted).
– If the thermostat is idle for fifteen seconds, the thermo-
stat times out, saves all changes, and returns to the ther-
mostat’s default display.
