How do I change the batteries on the
thermostat when they run out?
The thermostat constantly monitors the battery
power level, which typically lasts for about 2
years before needing replaced. When the power
is running low a flashing symbol will be
displayed on the screen. To change the batteries
follow the steps in the above section (‘STEP 1:
Installing the Batteries’ on page 3), replacing
the used batteries with new ones in Step c.
Note: While changing the batteries your program
settings will be stored but you may need to adjust
the time settings to be correct.
