If the current frequency is lower than COOL_F4, the frequency will not be limited.
After 10s of the compressor start, if the current>ICOOL,the AC will display the failure for 30 seconds
and stop. The AC will restart 3 minutes later.

HEAT_F16 IHEATLMT12 Decrease the frequecny to HEAT_F4 and run at
HEAT_F4 for 3 minutes.
After that,the frequency will be adjusted according to
the capacity demand and rise to the upper level every
3 minutes
(When the frequency>Heat_F4 via capacity
demand).

If the current frequency is lower than HEAT_F4, the frequency will not be limited.
After 10s of the compressor start, if the current>IHEAT,the AC will display the failure for 30 seconds
and stop. The AC will restart 3 minutes later.
6.5.5 Indoor / outdoor units communication protection
If the indoor units can not receive the feedback signal from the outdoor units for 2 minutes,the AC will stop
and display the failure.
7.5.6 High condenser coil temp. protection.
When T3>65 for
℃
3 seconds, the compressor will stop while the indoor fan and outdoor fan will continue.
When T3<52 , the protection will release
℃
and the compressor will restart after 3 minutes.
