OPERATING TIPS

Instructions relating to heating are applicable only to “HEAT & COOL MODEL” (Reverse Cycle).

Mode operation: AUTO

COOLING MODEL

When the room temperature is 4 °F higher than the set temperature, the mode will switch between Cooling and Drying.

During the Drying mode operation, the FAN setting should be switched to LOW for a gently cooling effect during which the fan may temporarily stop rotating.

HEAT & COOL MODEL (Reverse Cycle)
Auto changeover function

When AUTO CHANGEOVER is selected, the air conditioner selects the appropriate operation mode (Cooling or Heating) according to your room’s present temperature.

When AUTO CHANGEOVER is first selected, the fan will stop or operate at a very low speed for about 1 minute while the unit determines the current conditions of the room and selects the proper operation mode.

When the room temperature is near the thermostat setting, the air conditioner will begin monitor operation. In the monitor operation mode, the fan will stop or operate at a very low speed. If the room temperature subsequently changes, the air conditioner will once again select the appropriate operation (Heating or Cooling) to adjust the temperature to the value set in the thermostat. (The monitor operation range is ±4 °F relative to the thermostat setting.)

AUTO restart

Should the power supply to the air conditioner be interrupted by a power failure, the air conditioner will restart automatically in the previously selected mode once the power is restored.

Use of other electrical appliances (electric shaver, etc.) or nearby use of a wireless radio transmitter may cause the air conditioner to malfunction. In this event, temporarily turn off the circuit breaker turn it on again and then use the remote controller to resume operation.

Heating performance

This air conditioner operates on the heat-pump principle, absorbing heat from outdoor air and transferring that heat indoors. As a result, the operating performance is reduced as outdoor air temperature drops. If you feel that insufficient heating performance is being produced, we recommend you use this air conditioner in conjunction with another kind of heating appliance.

Heat-pump air conditioners heat your entire room by recirculating air throughout the room, with the result that some time may be required after first starting the air conditioner until the room is heated.

Fan speed: AUTO

Heating: The fan will stop or operate at a very low speed if the temperature of the airflow from the indoor unit is lower than the set temperature.

Cooling: As the room temperature approaches that of the set temperature, the fan speed becomes slower.

Fan: The fan alternately turns on and off; when on, the fan runs at the low fan speed.
