How Do You Change The Batteries In A Trane Thermostat. The same procedure goes for the heating setting. Looking to replace your batteries on your 800 series Trane thermostat.
Check the screen of the thermostat and make sure that it is lighted. Our thermostat died yesterday but after replacing the dead batteries with fresh batteries and confirming the LCD screen was operable our AC no longer turns on. Not everyone knows how to change their batteries in a thermostat.
So if you work or leave during the day you can change the temperature to reflect that and save even more money.
Remove and dispose of the old batteries. Do all thermostats have batteries. Pull the wall thermostat housing off. If you have a unit that uses battery power remove the front plate from the wall plate and change the batteries to see if this brings the thermostat back to life again.
