There are icons flashing on the thermostat display

There are several internal timers which influence the thermostat’s operation. If a timer is preventing the equipment from turning on, the display icons which show the equipment is operating, will be flashing to indicate a turn-on delay is present.

You get a system error message

Here are the possible system error messages and what they mean:

--The room air sensor reports that the room air temperature is above 150_F or below -50_F.

E4 The memory has failed and the thermostat will return to the factory settings.
