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”, and
an additional bold frame will appear around the EMER
button. 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.
