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 hold “▼” 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.
5.4.2 Manual Forced Defrosting
● When in non-defrosting stage, press and hole【▲】 for 7 seconds, the system starts forced
defrosting. When in defrosting stage, press and hole 【▲】 for 7 seconds, the defrosting stops.
5.4.3 Dropping Water Function
● System can be set” Dropping water time (U33)”. After defrosting, within “Dropping water time”,
system will not start cooling.
● This function will not work when:
◆ manual forced defrosting ◆ during defrosting, while defrosting sensor fails
5.4.4 Check Defrosting Data
● Check defrosting sensor temperature: When the digit show the room temperature, depress 【▲】,
the digits will show defrost sensor’s temperature. Do not keep depressing for 7 seconds; else the
device will launch forced defrosting.
● Check the left time of defrosting or dropping: During automatic defrosting or dropping process,
depress 【▼】, the digits show the left time.
5.5 High-temperature and Low-temperature warning
● When the test temperature ≥ “MAX TEMP”+ “U50”,and the time reaches to “U52 or U53”,high
temperature warning starts.
● When the test temperature ≦ “MIN TEMP”+ “U51”,and the time reaches to “U52 or U53”,low
temperature warning starts.
