Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. If my initial response doesn’t answer your question then let me know and we can continue our conversation.

Once you open the front cover you'll see 2 small screws at the bottom corners. Back those screws off then pull the bottom away from the wall and lift the thermostat off the pins a the top. Once it's off you see the batteries on the back of the thermostat body you just removed. Replace the batteries then hook the top then tighten the screws back up. You should set the thermostat to OFF before you do this.
