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.
