16.3.8 Condenser high temperature T3
protection
---55°C(131°F)<T3<60°C(140°F), the
compressor frequency will decrease to the
lower level until to F1 and then runs at F1.If
T3<54°C(129.2°F), the compressor will keep
running at the current frequency.
---T3<52°C(125.6°F), the compressor will not
limit the frequency and resume to the former
frequency.
---T3>60°C(140°F) for 5 seconds, the
compressor will stop until T3<52°C(125.6°F).
16.3.9 Evaporator low temperature T2
protection
---T2<0°C(32°F), the compressor will stop and
restart when T2≧5°C(41°F).
---0°C(32°F)≦T2<4°C(39.2°F), the compressor
frequency will be limited and decreased to the
lower level
---4°C(39.2°F)≤T2≤7°C(44.6°F), the
compressor will keep the current frequency.
---T2>7°C(44.6°F), the compressor frequency
will not be limited.
