Note: • Indoor fan is running at Me+ or below.
• After 420 minutes from the start of operation, the operation timer counting is restarted from "0".
d.
High Pressure Control at Minimum Frequency Control
•
When the outdoor air temperature increases to 38.6°C, compressor operating frequency reduces to
minimum of 33 Hz. Compressor operating frequency will resume to normal when outdoor air temperature
decreases to 37.8°C.
e.
Electrical Components Overheating Protection
•
When outdoor air temperature is 38.5°C or above and the compressor operating frequency is 25 Hz or above,
total running current set value is reduced (refer to Total Running Current Control) and the operating
frequency is reduced.
•
The protection control is cancelled when the outdoor air temperature decreases to 37.5°C or compressor
stops.
