Brief introduction to electric control function
3.2.1 Automatic running (applicable to
When the running mode is turned to automation after starting the system, the system will first determine the running mode according to the current room temperature and then will run according to the determined mode. Tr in the following selection conditions means room temperature, Ts means setting temperature, Tp means temperature of indoor coil
pipe |
|
|
a. Tr≥23℃ | running refrigerating mode | Ts=26℃ |
b. Tr<23℃ | running heating mode | Ts=23℃ |
After turning to the automation mode, the running mode can be switched between refrigerating mode, fan mode and heating mode according to the change of the indoor ambient temperature. But the automatic conversion between refrigerating mode and heating mode must be conducted after 15 minutes.

3.2.3 Dehumidification running
The compressor, outdoor fan and indoor fan will run as per the following working pattern so as to realize the refrigerating running of dehumidification:
3.2.3.1 Tr> Ts+2℃, compressor, outdoor fan run continuously, indoor fan runs as per setting wind speed (State 1);
3.2.3.2 Ts+2℃≥ Tr≥Ts, compressor, outdoor fan run intermittently with 10 minutes ON, 6 minutes OFF. (Compressor and outdoor fan are synchronous) indoor fan runs in fixed lower wind speed, and will cease at the
3.2.3.3 Tr <Ts, compressor, outdoor fan ceases, indoor fan runs in lower wind speed. (State 3)
