Someone gave me a unused White-Rodgers digital non-programmable heat
pump thermostat - 70 series model number 1F79-111.

I put some batteries in this thing to today just to check out the LCD
screen, and the temp reading is stuck on 72 degrees. Does this thing
have to be wired to show the correct temp?

Make sure there is no clear protective film with temperature printed on
it stuck over the LCD display. It happens! I got a call to fix an AC
that had no air flow after the customer had replaced the air filter. He
failed to remove the plastic wrapper from the new filter. In my best
loud obnoxious Judy Tenuta voice: "IT CAN HAPPEN!" ^_^
