How can I tell if my Cozy is operating properly?

Monica Ridgway -

The green LED on the sensor is your indicator of proper functionality. NOTE! These light are only visible during the start-up - there are no lights during normal operation.

If you think your Cozy is not operating properly, run this simple test:

  1. Unplug The Cozy
  2. Plug it back in
  3. A green light should shine from the wall temperature sensor. This will display for 5 seconds. You should also hear the fan turn on. If there is no light or a constant red light, please contact us at

For optimal results, keep your Cozy plugged in at all times and ensure the surrounding area is clutter free. Make sure the temperature sensor is not blocked and that the radiator valve remains open.
