(1) Compressor control

1 3 minute time delay

To prevent overload, the compressor will not start within 3 minutes after stop.

2 The compressor runs when the room temperature is higher than the set temperature.

The compressor stops when the room temperature is equal to or lower than the set temperature.

3 The compressor stops in check mode or during protective functions. 4 Coil frost prevention

To prevent indoor coil frost, the compressor will stop when the indoor coil thermistor (RT2) reads 1°C or below after the compressor has been continuously operated for 16 minutes or more. The coil frost prevention is released under any of the following conditions.

● The indoor coil thermistor rises to 10°C or above.

● The room temperature becomes equal to or lower than the set temperature.

● COOL mode is stopped or changed to another mode.

NOTE : By cutting the jumper wire JRO2 on the indoor controller board, the temperature to start coil frost prevention changes

from 1°C to -3°C.

5 Coil frost protection

When indoor coil temperature becomes -15°C or below, coil frost protection will proceed as follows.

After the compressor has been continuously operated for 3 minutes or more, and the indoor coil temperature has been

-15°C or below for 3 minutes, the coil frost protection will start.

Compressor stops for 6 minutes, and then restarts. lf the start condition is satisfied again during the first 10 minutes of compressor operation, both the indoor and outdoor units stop, and the remote controller displays this occurrence.

Coil frost protection is released when the start condition is not satisfied again during the allowance, or when the COOL mode stops or changes to another mode.

(2) Indoor fan control

Indoor fan speed LOW/HIGH depends on the remote controller setting. However, if an outdoor unit abnormality is detected, the indoor fan speed will be LOW, regardless of the remote controller setting.

(3) Detecting abnormalities in the outdoor unit

After the compressor has been continuously operated for 3 minutes, if the difference between the difference between the indoor coil temperature and room temperature is out of RANGE C, for 1 minute, the indoor fan speed will turn to LOW. Five minutes later, if the difference is in RANGE C, the fan speed will return to the set speed. If the dif ference is still out of RANGE C, the outdoor unit is deemed abnormal. Thus, the compressor will stop and the trouble location is indicated on the remote controller. RANGE A: Indoor coil temperature is more than 5 degrees above room temperature. RANGE B : Indoor coil temperature is within 5 degrees either way of room temperature. RANGE C : Indoor coil temperature is more than 5 degrees below room temperature.

3 The compressor stops in check mode or during protective functions. 4 The compressor will not start when the room temperature is below 18°C.

The compressor starts intermittent operation when the power is turned ON with room temperature above 18°C. The compressor ON / OFF time depends on the thermostat ON / OFF and the room temperature as follows. After 3 minute compressor operation,

● If the room temperature thermistor reads above 28°C with thermostat ON, the compressor will operate for 6 more minutes and then stop for 3 minutes.

● If the room temperature thermistor reads 26 °C ~28 °C with thermostat ON, the compressor will operate for 4 more minutes and then stop for 3 minutes.

● If the room temperature thermistor reads 24°C ~26°C with thermostat ON, the compressor will operate for 2 more minutes and then stop for 3 minutes.

● If the room temperature thermistor reads below 24°C with thermostat ON, the compressor will stop for 3 minutes.

● If the thermostat is OFF, regardless of room temperature, the compressor will stop for 10minutes.

5 Coil frost protection

Coil frost protection in DRY operation is the same as in COOL operation.

(2) Indoor fan control

The indoor fan runs on LOW speed during compressor operation. The fan speed cannot be changed with the remote controller. Also, the indoor fan does not run during compressor OFF.

(3) Detecting abnormalities in the outdoor unit

An abnormality in the outdoor unit can not be detected in DRY operation.

Service Ref. : PE-3EJA2.TH / PE-3EJA3.TH

Service Ref. : PE-4EJSA2.TH, PE-5EJSA 2.TH, PE-6EJSA 2.TH

Note 1. How to connect refrigerant pipes.

Factory supplied optional refrigerant piping contains refrigerant at the above atmospheric pressure. As long as connection takes no more than 5 minutes, no air will enter, and there will be no need for air purging. Remove the blind caps and make the connections within 5 minutes. After the connections for the indoor and outdoor units are made, open the stop valve on the outdoor unit to allow refrigerant gas to flow. If piping length exceeds 20m, an additional charge of refrigerant is needed.

Note 2. The following main parts are contained in the optional refrigerant piping kit.

Heat insulating cover, vinyl tapes, nipples, sleeve, flange (for wall hole).

2. REMOTE CONTROLLER EXTENSION CABLE

When installing the remote controller at a distance from the air conditioner, use the designated extension cable with connector.

3. TIMER

When using a program timer, a program timer adapter (PAC-825AD) is also needed.
