The meaning of the fault code is as follows:
E0 : 2 PCB communication anomalies . Generally due to the connection lines of the
2 boards are damaged or loose.
E1 : Too high water temperature protection. W ater temperature exceeds (target
value + C0), too high protection fault output interrupt signal.
E2 : Too low water temperature protection. W ater temperature lower than (target
value -C0), too low water temperature protection fault output interrupt signal.
E3 : Water shortage protection. The pump does not pump water, the water pipe is
blocked or the water flow is not smooth, and the water shortage protection is
started, and the output interrupt signal.
E4 : Refrigeration system fault. The cause of the fault is that the exhaust fan is
broken, the condenser is blocked by dust, the air inlet is not smooth and etc., and
output interrupt signal.
E5 : High voltage protection. The high voltage switch is disconnected and start
protection. Output interrupt signal. E6 : Low voltage protection. The low voltage
switch is disconnected and start protection. Output interrupt signal. E7 : High
room temperature protection. Output interrupt signal.
The protection or de-protection delay time is 2 seconds, and less than 2 seconds is
regarded as interference and do not start protection.
If you do not need the E3/E5/E6, these 3 protection, you can directly short the
sensor line.
After the fault protection is started, turn off the compressor and the heating rod,
open the protection output, and open the solenoid valve. When the fault is
removed, automatically resume working status. However, if it is E3 and E4
protection, only the protection relay will be activated, and other work will not be
affected.
When the power is turned on, the difference between the water temperature and
the target value may exceed the high and low temperature alarm limits. At this
time, the alarm cannot be made, but at the same time detect temperature trends:
