What if . . .

The battery icon is displayed

The battery icon appears on the display only when the battery
starts to lose power. Replace it when one-third of the icon is black.
If you wait until the icon is just a silhouette with no black bars, the
thermostat won't have the power to function correctly. Replace the
battery to restore thermostat functions.

"Aux heat on" is displayed (heat pump systems only)

Aux heat on is auxiliary heat. It applies only to the heat pump version.
If it is on, you will see aux heat on. When it is displayed, it means the
system has determined that it's too cold outside for your heat pump
to heat the house without help, so it's getting help from the electric
heaters. This happens automatically.

"Em heat" is displayed (heat pump systems only)

Em heat is the display term for emergency heat and applies only to
the heat pump version. When emergency heat has been turned on,
Em heat is displayed when you press the mode button. You have to
turn on emergency heat manually – it doesn't happen automatically
– so if you see Em heat on the display, it means somebody has
turned it on.
