2.2 HOW IT WORKS

Basic Operation Modes
AUTO Mode
In this setting the system will automatically change modes and fan speed to the set temperature.
[In spring and autumn, closer temperature control may require COOL/HEAT mode changes.]
DRY Mode
In this mode, priority is given to dehumidifying the air. Low fan speed and compressor cycling is used to
achieve this and regulate room temperature.
Compressor Delay
At start-up, a time delay of 3 to 4 minutes protects the compressor.
Cold Draft Prevention
To avoid uncomfortable drafts in heating mode, the indoor unit is preheated before the fan starts. This delay
should only last a few minutes.
Auto Defrost
Ice develops on the outdoor unit in heating mode. To defrost this ice, the indoor fan stops for a few minutes
before heating continues.
Auto Restart*
The unit will automatically restart after a power interruption. Previous user settings are all recovered.
Auto Leak Detection*
When refrigerant leakage is detected, the unit will display "EC" code or flash LEDs.

2.3 HINTS FOR ECONOMICAL OPERATION

Adjust the temperature to achieve moderate comfort levels. Excessively low or
high temperatures waste energy.
Improve performance by keeping windows and doors closed.
Limit energy usage [run time] by using the TIMER function.
Do not block air inlets or outlets. Poor performance, increased running costs
and reduced product life will result.
Inspect the air filters periodically, and clean them when needed.
Disconnect the power source if unit will not be used for a long period.
