When should I replace the batteries in my Smart Thermostat?

  • Always replace the batteries as soon as they have low battery levels. If the batteries drain, the thermostat could leave the HVAC system on or off, overheating or freezing the home.
  • If the thermostat buttons flash amber when pressed and the screen does not illuminate, the batteries in the thermostat are extremely low. Install fresh batteries immediately.
  • If the home is unoccupied for a month or more, such as vacation homes, replace the batteries as a preventive measure against battery failure while away.
  • It is also recommended to replace the batteries at least once a year. This will protect the thermostat from damage and corrosion by leaking batteries.
