Common Issues

Do you find yourself changing the battery in your Honeywell thermostat too frequently? Here are some common issues that can cause batteries to die quickly:

  • The wrong type of batteries: When selecting your batteries, ensure you use good quality alkaline batteries or lithium batteries. Avoid using rechargeable batteries as they tend to drain more quickly than standard batteries.
  • Short-circuiting: Short circuits can cause a significant increase in battery drain. Ensure that the metal ends of the batteries do not touch other metal parts of the thermostat or corrode.
  • Loose wiring: Loose wiring can also consume excessive battery power. It is important to ensure that any loose wires inside your thermostat are repaired.
  • Age of the thermostat: An old thermostat can cause the battery to drain quickly too. If your thermostat is more than five years old, consider getting a replacement.

To prevent the battery from dying quickly, you can also try to take steps such as lowering the screen brightness or setting the thermostat to an extended period when not in use.
