Hello,
We have a maple chase thermostat and the emergency light is red. It states on the manual that the "The EMER indicator is illuminated only when the system switch is moved
to the EM (emergency heat) position. The EM position is used only when
the primary stage of heat is not functioning or requires service." We definitely not using the heat (we are in Florida and it is August). Does anyone know what can be wrong?
Thanks

Broke maybe,, try killing the power to the furnace/airhandler at the breaker/fuse wait a minute and back on,, sometimes this will reset the system
