- Check and estimate the cause of short circuit, stop the unit operation once to cancel this error.

c. Ionizer Control Power Supply Error Detection

- During ionizer stopped, power is supplied to the ionizer due to indoor PCB error.
- During this error:

• TIMER LED blinks and unit stop operation
• Ion LED blinks
• error code H26 is indicated

- Exchange main PCB to cancel this error.

1. The compressor starts the operation, it will not stop its operation for 30 seconds.
2. This control is not applicable if the power supply is cut off and on again or after 4-way valve deices condition.

1. Once compressor starts the operation, it will not stop its operation for 30 seconds.
2. However, it can be stopped with the remote control or the Auto Switch on the indoor unit.

1. When the outdoor unit total running current (AC) exceeds X value, the frequency instructed for compressor operation will be

decreased.

2. If the running current does not exceed X value for ten seconds, the frequency instructed will be increased.
3. However, if total outdoor unit running current exceeds Y value, compressor will be stopped immediately for 3 minutes.

4. The first 30 minutes of cooling operation, (A) will be applied.

A. Overheating Prevention Control

1. When the IPM temperature rises to 110

qC, compressor operation will stop immediately.

2. Compressor operation restarts after three minutes the temperature decreases to 95

qC.

B. DC Peak Current Control

1. When electric current to IPM exceeds set value of 30.0 ± 5.0 A, the compressor will stop operate. Then, operation will

restart after 3 minutes.

2. If the set value is exceeded again more than 30 seconds after the compressor starts, the operation will restart after two

minutes.

3. If the set value exceeded again within 30 seconds after the compressor starts, the operation will restart after one minute. If

this condition repeats continuously for seven times, all indoor and outdoor relays will be cut off.

Instructed frequency for compressor operation will be regulated by compressor discharge temperature. The changes of frequency
are as below figure.
If compressor discharge temperature exceeds 110

qC, compressor will stop, occurs 4 times per 20 minutes, timer LED will be

blinking. (“F97” is to be confirmed.)

The compressor operating frequency is regulated in accordance to the outdoor air temperature as shown in the diagram below.
This control will begin 1 minute after the compressor starts.
Compressor frequency will adjust base on Outdoor Air Temperature.

i. Pipe temperature limitation/restriction

• Detects the Outdoor pipe temperature and carry out below restriction/limitation (Limit the compressor Operation frequency)
• The compressor stops if outdoor pipe temperature exceeds 61

qC

• If the compressor stops 4 times in 20 minutes, Timer LED blinking (F95: outdoor high pressure rise protection)

1. To prevent dew formation at indoor unit discharge area.
2. This control will be activated if:

• Outdoor air temperature and Indoor temperature judgment by microcontroller is fulfilled.
• When Cooling or Dry mode is operated more than 30 minutes or more.

3. This control stopped if:

• Compressor stopped.
• Remote control setting changed (fan speed / temperature).
• Outdoor air temperature and indoor intake temperature changed.

4. Fan speed will be adjusted accordingly in this control.

1. When indoor heat exchanger temperature is lower than 0

qC continuously for six minutes, compressor will stop operating.

2. Compressor will resume its operation 3 minutes after the indoor heat exchanger is higher than 7

qC.

3. At the same time, indoor fan speed will be higher than during its normal operation.
4. If indoor heat exchanger temperature is higher than 7

qC for five minutes, the fan speed will return to its normal operation.

36

Compressor will operate at Max frequency if below condition occur:

1. When the indoor intake air temperature is 30

qC or above.

The maximum current value is regulated when the outdoor air temperature rises above 16

qC in order to avoid compressor

overloading.

The compressor operating frequency is regulated in accordance to indoor heat exchanger temperature as shown in below figures.

When indoor pipe temperature is low, cold draught operation start where indoor fan speed will be reduced.

When outdoor pipe temperature and outdoor temperature is low, deice operation start where indoor fan motor and outdoor fan

motor stop and operation LED blinks.
