Hi I'm Brian and I'm here to help!

Yes, your thermostat does have batteries. It holds 3 AAA alkaline batteries on the back of the face of the thermostat. You pull the thermostat face off by disengaging the front from the back by pulling it straight off. The batteries are on the back of the section you take off.

However, your thermostat should have 24 volts powering it from the air handler. There may be a problem there. Try changing the batteries first and let me know what happens then.

Thanks,

Brian
