There are on-screen indicators to show you when the thermostat is calling for heating or cooling to occur. In the Heat mode switch position, a flame will be present on the screen. A steady flame means that the thermostat is not calling for your heating system to run, while a flashing flame means that your heating system should be currently running. In the Cool mode switch position, a snowflake will be present on the screen. A steady snowflake means that the thermostat is not calling for your cooling system to run, while a flashing snowflake means that your cooling system should be currently running.

EMERGENCY HEAT: (Heat Pump Configuration Only). While in normal Heat mode, one single press of the EMER button will activate Emergency Heat mode. While in Emergency Heat, the top of the screen will change from “Heat Mode” to show “Emer Heat”. A single press of the EMER button again will end Emergency Heat, and return back to normal Heat mode. If a power loss occurs while in Emergency Heat mode, the thermostat will continue to remain in Emergency Heat mode even after the power comes back on.

Emergency Heat mode will prevent the first stage of your heat pump system from turning on, and use only the “W2” heat terminal (Auxiliary Heat) as the primary heating source. This will not only prevent the heat pump from wasting energy if outdoor temperatures are too low to support efficient operation, but it could also prevent damage to the heat pump if outside temperatures are below the manufacturer’s recommendations. As every heat pump has different operating characteristics, you should refer to your heat pump literature to determine when to disable the heat pump and run in Emergency Heat mode.
