D. Fundamental functions
Cooling mode
1 The running conditions and control measures
a. If T in > or = T set + 1
o
C , the machine runs at the cooling mode. Compressor runs,
outdoor motor runs at low speed , indoor fan runs at the set fan speed.
b. if T in > or = T set –1
o
C , the machine stops. Compressor stops first, outdoor motor
stops after 15 seconds, indoor motor runs at the set fan speed.
c. if T set –1
o
C T in < T set + 1
o
C ,keep the previous state.
2 In this mode, the reversing valve is inactive, the temp. setting range is from 16~30
o
C.
3 Protect function
a. Anti-freezing function.
i. If compressor have run 6 minutes , and detect T eva < 0 for continuous 3
minutes, then the compressor outdoor fan stopped , indoor fan run at the set fan
speed. After 3 minutes later, it will run at the original state if T eva 10
o
C.
b. Compressor protection
i. Compressor’s starting interval should be more than 3 minutes no matter in what-
ever modes and conditions. If it’s plugged in first time, the compressor does not
have 3 minutes delay. When compressor is started, it will not stop within 5 min-
utes unless it is plugged out.
