1. When the LO Battery indicator is flashing, replace the 

batteries promptly with three fresh AAA alkaline 

batteries

2. Remove thermostat from the wallplate by pulling 

straight out.

3. Remove the old batteries and insert three fresh AAA 

alkaline batteries, as marked on the thermostat.

4. Align the screw blocks with the pins on the back of the 

thermostat.

5. Push the thermostat straight onto the wallplate until it 

snaps into place.

1. Replace the batteries as soon as LO Batt flashes in the 

display. The LO Battery indicator flashes in the display 

one month before the batteries run down completely.

2. Always use fresh AAA alkaline batteries. Non-alkaline 

batteries do not last as long and can leak, causing 

thermostat damage.

3. Although the thermostat has a Low Battery indicator, 

replace the batteries once a year to prevent the thermo-

stat and heating/cooling system from shutting down due 

to lack of battery power.
