13.2 Protection Control for Heating Operation

13.2.1 Outdoor Air Temperature Control

The maximum current value is regulated when the outdoor air temperature rises above 14°C in order to avoid
compressor overloading.

13.2.2 Deice

Operation

When outdoor pipe temperature and outdoor air temperature is low, deice operation start where outdoor fan motor
stop.

13.3 Protection Control for Cooling Operation

13.3.1 Outdoor Air Temperature Control



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.

13.3.2 Freeze Prevention Control 1

1 When indoor heat exchanger temperature is lower than 0°C continuously for 10 seconds, compressor will

stop operating.

2 Compressor will resume its operation three minutes after the indoor heat exchanger is higher than 1°C.
3 Indoor heat exchanger freeze prevention (H99) will memory in error history.
