How to change batteries on a Maple-Chase thermostat

Lynnmcd.

Make sure it is wireless. If it has wires running to the furnace i.e.. Small wires that look like telephone wires, it probably doesn't have batteries. If it is a wireless thermostat you should be able to find a small access panel somewhere. It may have to come off the wall. The batterys may be in back. Do you know the model #. Hope this helps

Yes it did, thanks much!
