In this video you will learn how to change the batteries in a wireless thermostat.
When the battery symbol is showing on your thermostat, this is the time to change the batteries in your wireless thermostat. To do this, loosen the two screws underneath (no need to remove them completely) and lift the thermostat off the bracket. You will then see on the back the batteries which can be replaced. Return the thermostat to the bracket, tighten the screws, and you should be back in working order.
