1) High pressure protection and air expelling temp. in system A of No.1 unit. (Protected code P0)
2) High pressure protection and air expelling temp. in system B of No.1 unit. (Protected code P2)
3) Low pressure protection in system A of No. 1 unit. (Protected code P1)
4) Low pressure protection in system B of No. 1 unit. (Protected code P3)
5) Fixed rated compressor: Air expelling temp. switch connect with system high pressure switch in series.

Water flow detection of No. 1 unit (Error code of main unit is E0), which only available for main unit, but auxiliary unit.
Main unit: Error code E9 displays at main unit LCD when abnormity occur at the first and second times. At the third
time of flow abnormity, error code E0 displays at main unit LCD (It is necessary to cut off power to remove of it.). For
error code E0 of Wired controller (It will display after the third detection.)
Auxiliary unit: (Short connect the unit by shorted wiring group but no water flow detection.)
5
COM (O) 485 (communication interface)of No.1 unit. (Error code E2).
6
1) COM (I) 485 (communication interface)of No.1 unit. (Error code E2).
2) P, Q and E ports of COM (i) connect with COM (O) used for RS-485 communication.
Provided that malfunction occur between in Wired controller and main module unit, i.e. all module units would stop
down.
Provided that malfunction occur between in auxiliary and main units, i.e. the error auxiliary module unit would shut
down, units’ quantity detected by Wired controller would decrease, and display EA at Wired controller LCD, indicator
of that flashing at the same time.

T41 of No.1 unit: outdoor ambient temp. sensor (Error code E7).
As long as one outdoor fan unit in this system requires for open, then electric control of the unit turn on this fan. Start
outdoor fan A only, start A and B gears, and control the unit through T41.
