Customer Question
My thermostat is saying...

My thermostat is saying replace battery but I can't find my instruction book. What do I do?

Contractor's Assistant: Just to clarify, do you think this is a larger HVAC problem, or something specific to the thermostat?

I think just the thermostat. The system was checked not long ago

Contractor's Assistant: Do you plan on doing the work yourself?

Either me or my son-in-law

Contractor's Assistant: Anything else we should know to help you best?

I don't think so. Just need to know how to change it.

Hello,

This could vary with the style thermostat. Do you know the model or can post a pic?

You can grasp the entire front and pull the bottom out and upward...would you like to try this or wait?
