Temporary Temperature Hold
You can temporarily adjust the tem-
perature in your home at any time while
your thermostat is running a program by
touching either
or keys. The dis-
play will indicate “Temporary Hold At”

cancel the temporary setting before the
next period begins, touch Run Schedule
to return to the program.
Example: If you turn up the heat during
the Morning program, it will remain at the
new temperature until the time for the
next program period (Day program).
Touch the SYSTEM key to select the
thermostat operating mode desired.
When the system is calling for first stage
heat or cool, “Low” will display on the
touchscreen. When second stage is re-
quired, the display will show “High”. The
setpoint temperature can be changed by
touching the
or keys.

Auxiliary Heating when the outside tem-
perature is too cold for the heat pump to

Heat pump malfunction is rare, but
should it happen, Emergency Heat can
