heating mode:
a. Outdoor coil Temperature (OPT)
≥15
℃
.
b. The time of defrosting keeps for more than 10 minutes.
(5) Indoor exchanger overheat protection
When IDU Pipe (
exchanger
) Temperature (IPT) is higher than 55
℃
, unit comes into indoor
exchanger overheat protection. The compressor drops its frequency toward to F1 level until
IPT
≤52
℃
If IPT
≤52
℃
and keep for 5 minutes,
control system doesn’t limit running frequency.
If IPT>62
℃
, control system shut down compressor, and recover while IPT drop less than 50
℃
.
