Hot-start Control (Heating)

• The indoor fan stops until the evaporator piping temperature will be reached at 25°C.

High head height Drain pump(Optional)

• A standard drain-head height of up to 700mm is possible.

Central Control(Optional)

•

It is operating individually or totally by central control function.

Group Control(Optional Wiring)

•

Each controller can control 16 units and 8 controllers can connect.

•

It operates maximum 16 units by only one wired remote controller and each unit starts random to prevent overcurrent.

• Room temperature sensor. (Thermistor)

•

Maintains the room temperature in accordance with the Setting Temp.

• Indoor fan is delayed for 5 seconds at the starting.

• Restarting is inhibited for approx. 3 minutes.

• High, Med, Low

• Intermittent operation of fan at low speed.

• Although the air-conditioner is turned off by a power failure, it is restarted automatically previous operation mode after power supply.

• The setting temperature and desired operation mode are automatically set by fuzzy rule.

• Both the indoor and outdoor fan stops during defrosting.
