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.
FAQ’s
How do I set one temperature for the whole day?
To operate as a simple thermostat with one temperature throughout the day, select the manual operating mode by pressing the MAN button. Adjust the temperature by
pressing the 
or 
buttons - this can be set anywhere from 5°C to 35°C in 0.5°C steps. The thermostat will continue to maintain this temperature until another operating mode is selected or the temperature is adjusted.
