What does the message on my Lyric that says Thermostat Power Lost mean?

Last updated


This is an indication that power to your Lyric thermostat has been interrupted. You will need to confirm that your heating and cooling system is still powered. Check that the circuit breaker is in the on position and hasn't been tripped. If you have a switch on your heating or cooling equipment itself, please verify that the switch is in the on position as well. If everything is powered as expected but your Lyric thermostat is still offline, please contact Lyric Technical Support for assistance at 1-800-633-3991 or contact your contractor.
