49 WHATIF... “Auxiliary heat on” is displayed (heat pump and Hybrid Heat systems only) Auxiliary heat onapplies only to the heat pump version. If it is on, you will see auxiliary 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 and Hybrid Heat systems only) Em heatis the display term for emergency heat and applies only to the heat pump version. When emergency heat has been turned on,Em heatis displayed. You have to turn on emergency heat manually – it doesn’t happen automatically – so if you seeEm heaton the display, it means somebody has turned it on.
