Auto restart
The air conditioner will automatic restart when electricity is restored after a power
cut. If in doubt, check the settings.
Range of internal thermostat
The internal thermostat can be set at a desired temperature between 16 and 32 °C.
Note that whether the desired value is achieved depends on conditions in the room.
Range of heat pump function
The heat function can be used to supply low cost heat when the external
temperature is approximately 10 °C or higher.
Note that it may not operate properly at lower external temperatures, it will cycle
frequently to defrost the outdoor coil and stops operating at minus 5 °C.
Capacity
The required cooling or heating capacity depends greatly on the location and/or use
of the room where the air conditioner is installed. Strong sunlight and the presence
of people, lights or equipment create an additional heat load with resulting smaller
reduction in room temperature.
Normal living spaces require about 100 W per square metre of floor surface. In
strong sunlight or if other sources of heat are present, this may be as much as
350 W/m

.
Tip: on warm days, let the air conditioner cool the room as much as possible during
the night. Cold walls and furniture will help to keep the room pleasant during use.
Avoid strong sunlight.
Aim for a room temperature only up to 3–5 °C lower than ambient temperature to
save energy and shock to the body when moving out of the conditioned space. The
air conditioner will dry the air, making it more comfortable even if not very cold.
