IPM Overheating Prevention Control
• If temperature of IPM exceeds 103
q
C, compressor will be stopped. It will restart in 2 minutes. Temperature for restarting: 90
q
C.
• If the excess occurs 4 times within 30 minutes after compressor starts, the compressor will be stopped and timer LED on the
indoor unit will be blinking. (“F96” is to be confirmed.)
12.2.5.
Compressor Overheating Prevention Control
1. If discharge pipe temperature exceeds 100
q
C, compressor power will be limited.
2. If discharge pipe temperature exceeds 112
q
C, compressor will be stopped.
3. If the above excess occurs 4 times per 10 minutes, timer LED will be blinking. (“F97” is to be confirmed.)
12.2.6.
Outdoor High Pressure Prevention Control (Cooling and Dry operations)
1. If outdoor heat exchanger temperature exceeds 63
q
C in cooling or dry operation, compressor will be stopped.
2. Timer LED is not blinking. (“F95” is memorized, then.)
12.2.7.
Compressor Protection Control (Refrigeration Cycle Abnormality)
In cooling and Dry operations
1. When compressor is operated continuously for 5 minutes in the maximum cooling power: a running current of 0.7 - 1.4A and
“[Indoor intake air temperature] - [Indoor heat exchanger temperature]” < 4
q
C, compressor will be stopped.
2. If the above excess occurs twice for 20 minutes, timer LED is to be blinking. (“F91” is to be confirmed.)
In Heating operation
1. When compressor is operated continuously for 5 minutes in the rated heating power: a running current of 0.7 - 1.4A and
“[Indoor heat exchanger temperature] - [Indoor intake air temperature]” < 5
q
C, compressor will be stopped.
2. If the above excess occurs twice for 20 minutes, timer LED is to be blinking. (“F91” is to be confirmed.)
12.2.8.
Four-way Valve Operation Detection Control (Switching Abnormality between
Cooling and Heating)
In Cooling operation
1. When indoor heat exchanger temperature exceeds 45
q
C in 4 minutes after compressor starts, compressor will be stopped.
2. If the above excess occurs 4 times per 30 minutes, timer LED is to be blinking. (“F11” is to be confirmed.)
In Heating operation
1. When indoor heat exchanger temperature is below 0
q
C in 4 minutes after compressor starts, compressor will be stopped.
2. If the above excess occurs 4 times per 30 minutes, timer LED is to be blinking. (“F11” is to be confirmed.)
12.2.9.
Anti-Freezing Control (Cooling and Dry operations)
Limit of Cooling power
1. When temperature of indoor heat exchanger is below 5
q
C, operating frequency will be decreased.
2. When temperature of indoor heat exchanger exceeds 7
q
C, operating frequency will be increased. (But, up to programmed
frequency.)
3. When temperature of indoor heat exchanger is below 0
q
C continuously for 6 minutes, compressor will be stopped.
4. Timer LED is not blinking. (“F99” is memorized, then.)
Limit of Indoor fan speed
• When temperature of indoor heat exchanger is below 6
q
C (2
q
C at Dry) continuously for 6 minutes, indoor fan speed will be
increased by 50 rpm.
12.2.10. Outdoor Air Temperature Control
In Cooling and Dry operations
1. When outdoor air temperature is below 25
q
C, the maximum power will be limited up to about 80 - 100% of the rated power.
2. When outdoor air temperature is below 18
q
C, the maximum power will be limited up to about 50 - 100% of the rated power.
3. When outdoor air temperature is below 11
q
C, the maximum power will be limited up to about 26 - 81% of the rated power.
12.2.11. Indoor Intake Air Temperature Control (Heating operation)
1. When indoor air temperature is 35
q
C or more, the maximum power will be limited up to the rated power.
2. When fan speed is set at “Lo” and intake air temperature is below 21
q
C, the maximum power will be limited up to the rated
power.
