5.2.2.5. Anti-frosting protection
While condition a), b) matched, the AC unit transferred to anti-frosting protection.
a). After the compressor continual works for 6 minutes, and tested IPT
≤0
℃
for 3 minutes continuously.
b). After the compressor continual works 6 minutes, and tested IPT
≤-2
℃
for 3 seconds continuously.
c). AC unit quit protection while IPT≥10
℃
.
5.2.3 Dry mode
5.2.3.1. Temperature control: 16~31
℃
.
Fan speed: low
Vane blade position: as customer preset
5.2.3.2. When ODU failure or stops for protection, IDU works as preset.
5.2.3.3. Compressor and process control
1). When RT-
ST≥1
℃
, the compressor starts up working, AC operates as customer preset;
2). When
a. RT-ST
＞
2
℃
, the compressor will start up operation once it stops 3 minutes, and unit without any other protection
or failure code.
b. RT-ST
＜
-2
℃
, the compressor will stop working while it works 6 minutes or more continuously.
c. -2
℃
≤RT-ST≤ 2
℃
，
the compressor will stop working while it works for 6 minutes, after 4 minutes it will start working
again.
3). The compressor will also stop working while unit:
a. switched off.
b. under protection.
c. changed to fan mode.
4). Under normal operation, the compressor can be stopped by program until it works for 6 min at least once starts up.
5). In the process of unit operation, once the compressor ceased, it should be 3 min delay for the next procedure.
5.2.3.4. ECO and sleep mode: Invalid.
5.2.3.5. Anti-frosting protection
While any of condition a), b), or c) matched, the AC unit transferred to anti-frosting protection.
a). After the compressor continual works for 6 minutes, and tested IPT
≤0 ℃
for 3 minutes continuously.
b). After the compressor continual works 6 minutes, and tested IPT
≤-2 ℃
for 3 seconds continuously.
c). If the unit works as 6 minutes ON, 4 minutes OFF, and tested IPT
≤0
℃
for 3 minutes continuously.
d). AC unit quit protection while IPT≥10
℃
.
5.2.4 Heating mode
5.2.4.1. Temperature control: 16-31
℃
(61-88
℉
).
5.2.4.2. Compressor and process control.
1). When ST-
CRT≥1
℃
, the compressor starts up working, AC operates as customer preset;
2). When
a. ST-
CRT≥1
℃
, the compressor will start up operation once it stops 3 minutes, and unit without any other protection
or failure code.
b. ST-
CRT≤-1
℃
，
the compressor will stop working while it works 6 minutes or more continuously.
c. -1
℃
＜
ST-CRT
＜
1
℃
，
the compressor keeps original state.
3). The compressor will also stop working while unit:
a. switched off.
b. under protection.
c. changed to fan mode.
4). Under normal operation, the compressor can be stopped by program until it works for 6 min at least once starts up.
5). In the process of unit operation, once the compressor ceased, it should be 3 min delay for the next procedure.
5.2.4.3. IDU time delay: When compressor stops or unit switches off while in heating mode, IDU fan motor keeps
working for 50 seconds.
