1) Main unit: if abnormal water flow occurs for the first and second time, the main unit board will display fault code E9.
2) Subordinate unit: (Water flow detection will not be done).
18
COM (I) 485 communication port (Fault code E2).
COM (O) is interconnected with P, Q and E of COM (I), used for RS-485 communication.
1) If faults occur between the wired controller and the main unit module, all modules will be shut down.
2) If faults occur between the main unit and subordinate units, the subordinate unit module suffering communication fault will
be shut down. Less units will be detected by the wired controller, which may display EC, and in the meanwhile, the indicator
lamp of the wired controller will flash.
Restart 3 minutes later after malfunction be removed.
19
COM (O) 485 communication port (Fault code E2).

Anti-freezing pressure protection in system A(Protection code Pc).
Anti-freezing pressure protection in system B(Protection code Pd).
21
The alarm signal output of the unit(ON/OFF signal).
22
Auxiliary electric heater:
Attention: the control port value of auxiliary electric heater actually detected is ON/OFF but not 220V control power supply, so
special attention should be paid when installing the auxiliary electric heater.
Attention!
Under heating mode, when the main unit board detects total water outlet temperature to be lower than 45
℃
, the switch will be
closed, and the auxiliary electric heater will begin to work; when the total water outlet temperature is higher than 50
℃
, the
switch will be opened, and the auxiliary electric heater will stop working.
23
PUMP.
Attention: the control port value of the pump actually detected is ON/OFF but not 220V control power supply, so special
attention should be paid when installing the pump.
1) After receiving start-up instruction, the pump will be started up instantly, and will maintain start-up state always in the
process of operation.
2) In case of refrigerating or heating shutdown, the pump will be shut down 2 minutes after all modules stop operating.
