(c)

To accomplish rapid recovery from the thermostat off state, after the compressor and outdoor unit’s fan go OFF, the set

temperature is raised by 1ºC until 1 minute passes after the hot keep end temperature has been reached following restarting.

(5)

Hot Spurt

(a)

For 40 minutes after a heating operation begins, the system runs with set temperature raised by 2ºC.

(b)

In the following cases, this function is canceled and does not activate afterwards.

1) When the compressor and outdoor unit fan have been turned OFF by the thermostat going off.

2) During high pressure control operation.

(6)

High Power Operation (“HI POWER” button on the remote controller : ON)

The system runs under the following conditions for 15 minutes without relation to the set temperature or the fan speed setting.

(7)

Defrost Operation

(a)

Starting conditions (Defrost operation begins when all the following conditions are satisfied.)

1

40 minutes have passed since the heating operation began. (Accumulated operation time)

2

40 minutes have passed since the previous defrosting operation ended. (Accumulated operation time)

3

The outdoor unit heat exchanger thermistor temperature is –5ºC or lower continuously for 3 minutes.

4

The difference between the outdoor temperature thermistor temperature and the outdoor heat exchange thermistor tem-

perature is => 4.5ºC.

5

The compressor is running.

Also, the number of times the compressor goes OFF is counted, and when it reaches 10 or more times, if the conditions

in 

1

, 

2

 and 

3

 above (except that the outdoor heat exchanger thermistor temperature is –1ºC), the defroster operation

starts.

(b)

End conditions (when either of the following conditions is satisfied)

1

Outdoor heat exchanger thermistor temperature: 9ºC or higher

2

Defrosting operation has continued for 10 minutes.

Notes (1) Room temperature is not adjusted during the HI POWER operation.

(2) Protective function will actuate with priority even during the HI POWER operation.
