How to Replace the Thermostat Batteries in Your Florida Home

how to replace thermostat batteriesOne advantage the manual thermostat had over a digital programmable thermostat was simply the fact that you never had to replace the batteries – it didn’t have any. Unfortunately, avoiding that minor task is the only advantage old-school manual models offered. Programmable thermostats empower the Largo homeowner to adjust the indoor environment to the occupant’s daily routines. Once the thermostat is programmed, settings are executed automatically without further input from residents. Consistency means increased system efficiency, and a correctly programmed thermostat can save up to 20 percent on annual heating and cooling expenses.

While some programmable thermostats get power from the HVAC system – batteries are only a backup provision – many models are entirely battery powered. A programmable thermostat is most commonly powered by either 1.5-volt AA or AAA alkaline batteries, although a few models utilize a mercury “button” battery. In most cases, once the flashing “Low Battery” message appears on the LCD screen, you have up to 60 days to install new batteries. When the old batteries are completely exhausted, the screen will go blank and you may lose your programmed thermostat settings.

How to Replace the Batteries in a Thermostat

  1. Switch the system to “Off” on the thermostat.
  2. Remove the thermostat from its wall mounting plate. In most cases, this is done by simply sliding it upwards in the mounting bracket. Check the owner’s manual for specific instructions.
  3. On the back of the thermostat, there may be a small access door to an enclosed battery compartment or simply open slots for batteries.
  4. Insert the batteries, paying attention to the icons indicating correct plus/minus polarity of the battery terminals.
  5. Close the battery compartment cover (if installed) and reinstall the thermostat on the wall plate.
  6. Switch the system to the “On” position. Depending on the model, there may be a delay of up to five minutes after installing batteries before the normal display reappears on the LCD screen. In some cases, you may have to reset the time on the thermostat clock display, also.
