5. Control Function Description
5.1 Compressor Control
● When the temperature
≧
“MAX TEMP”, and the time that the compressor has stopped
≧
“the valve of
U10”, the compressor starts.
● When the temperature
≦
“MIN TEMP”, and the time that the compressor has run
≧
“the valve of U11”,
the compressor stops.
● Compressor emergent on
Press and hold “▼” key for five seconds, the compressor will power on if the following meets:
◆
controller in non-defrosting status
◆
controller in non-dropping water status
◆
the compressor stops
In compressor emergent on status, press and hole “▼” key for five seconds, the mode exits.
5.2 Compressor Delay Protection
● After power supply, the compressor is able to start only after the time(U10) has passed.
● After the compressor stops, it is able to restart again only after the time(U10) has passed.
● After the compressor starts, it is able to stop only after the time(U11) has passed.
5.3 Temperature Sensor Failure Protection: Protected Running Mode
●
When the room temperature sensor fails, the system will automatically run in the protected running
mode. In this mode, the compressor will run and stop with the period of 30 minutes. Compressor works
for U12* 3 minutes, stop for
﹛
30 - (U12* 3)
﹜
minutes.
Note: If U12=0, system stops when sensor fails
5.4 Defrosting Function
5.4.1 Automatic Defrosting
●
When the compressor continuously running time reaches the time of defrost cycle (U30), the system
starts to defrost.
●
When one of the conditions (defrosting end time(U31) and defrosting end temperature(U32)) meets,
the defrosting stops.
