Customer Question

My themostat is flashing Lb or L6 - not sure which it is.
If it is Lb, meaning Low Battery, how do I get the cover off to replace the battery.
Thank you.

Yes that is a low battery code. look around the thermostat for any small screws, if you do not have any you can pop the cover off to the unit with your hands. If you have the model number and make I can get you better instructions for it.
