−
third of the icon is black.

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 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

happen automatically – so if you see

on the display, it means somebody
has turned it on.
