Operating Instructions

Mode Control

HIGH COOL and AUTO COOL provide cooling with different fan speeds.

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

LOW FAN 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.

Care and Cleaning

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.
