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
o
C 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 > or = 10
o
C.
b. Compressor protection
i. Compressor’s starting interval should be more than 3 minutes no matter in whatever 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 minutes unless it is plugged out.
c. Overload protection
i. If it detect the system current surpass the designed 13 A for continuous 3 minutes, the
machine go into fan mode, when 3 minutes passed and it detect the current no more than 13
A, it will back to original state. If it detects overloading states for 6 consecutive times, the
machine stops, and must be restarted by remote controller.
