1.3.2.4 Evaporator low temperature T2 protection.
For 12K models
：
---T2<0
℃
, the compressor will stop and restart when T2
>=
5
℃
.
---0
℃
≦
T2<4
℃
, the compressor frequency will be limited and decreased to the lower level
---4
℃
≤T2<7
℃
, the compressor will keep the current frequency.
---T2>7
℃
, the compressor frequency will not be limited.
For FWDB18/024
- When T2<2
℃
and lasts for 3 minutes, the indoor has no capacity demand and resume till T2
≥
7
℃
.
- When set point <17
℃
,and the T2<7
℃
, the indoor fan will be forced to run the speed RAFANC6 (1200
rpm for FWDB18, 1350rpm for FWDB24) till the T2>10
℃
For other models: When T2<2
℃
and lasts for 3 minutes, the indoor has no capacity demand and resume till
T2
≥
7

<T3<60
℃
, the compressor frequency will decrease to the lower level until to F1 and then runs at F1.If
T3<55
℃
, the compressor will keep running at the current frequency.
---T3<52
℃
, the compressor will not limit the frequency and resume to the former frequency.
