SYSTEM MODE
The
SYSTEM
button selects the system mode of operation —
OFF
,
COOL
, or
HEAT
. If the system is a heat pump,
there is also a selection for
AUX
to operate the auxiliary heat.
FAN MODE
The
FAN
button selects whether the fan should:
• Operate constantly to circulate air regardless of the System Mode setting, or call for Heat or Cool. This is
indicated by displaying
FAN ON
on the display.
• Operate only during a call for Heat or Cool. This is indicated by a lack of
FAN ON
on the display.
AUX
should only be selected if the heat pump cannot supply ample heat in extreme cold conditions or in the
event the heat pump is not operational. Selecting
AUX
can increase electricity use and costs.
