cooling with different fan speeds.
HIGH HEAT
and
AUTO HEAT
provide
heating with different fan speeds.

or
HIGH FAN
provides air
circulation and filtering without cooling
or heating.
NOTE: If you move the switch from a cool or heat
setting to STOP or to a fan setting, the unit has an
automatic 3-minute delay before allowing the
compressor to restart in the cool or heat mode.
Temp Control
The temp control is used to maintain the
room temperature. The compressor will
cycle on and off to keep the room at the
same comfort level. When you turn the
knob to
COOLER
(blue) the indoor air
will become cooler. Turn the knob to
WARMER
(red) and the indoor air will
become warmer.
3500 Series only
When the outdoor temperature is lower
than 25°F, heat is provided by the electric
heater in the air conditioner instead of by
the heat pump.

About Your Heat Pump (3500 Series only)
Heat pumps can save money by removing heat
from the outside air—even when the outside
temperature is below freezing— and releasing
that heat indoors.
To get the best performance from your heat
pump, don’t change the room thermostat very
often. Raising the heat setting 2–3 degrees will
cause the Zoneline to use its electric heating
elements in order to reach the new temperature
setting quickly.
There is a three minute minimum compressor
run time at any setting to prevent short cycling.
The indoor fan motor starts before the
compressor and stops after the compressor
cycles off.
The electric heating elements use much
more electricity than heat pumps and cost
more to operate.
