D. fundamental functions
1.cooling mode
(1)the running conditions and control measures
a. if T
in
T
set
+ 1 , the machine runs at the cooling mode. Compressor and outdoor motor runs,
indoor fan runs at the set fan speed.
b. if T
in
T
set
-1 , 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 T
in
T
set
+1 ,keep the previous state.
(2)in this mode, the reversing valve is inactive, the temp. setting range is from 16
to 30 .
(3)Protect function
a. anti-freezing function.
if compressor has run 6 minutes , and detects T
eva
< 0 for continuous 3 minutes, then the
compressor stops, outdoor fan stops after 15 seconds, indoor fan runs at the set fan speed. After
3 minutes later, it will runs at the original state if T
eva
10 .
b. compressor protection
Compressor’s starting interval should be more than 3 minutes no matter in whatever modes
