T3-1B of No.1 unit: Pipe temp. sensor of condenser B (Error code E6, protection code E7).
10
1) T3-1A of No.1 unit: Pipe temp. sensor of condenser A (Error code E5, protection code E6).
T3-1A,T3-1B: When system outdoor pipe temp. T3-1A or T3-1B be tested by module electric control is over than the
protection temp. 65
℃
, the corresponding system would shut down, until the temp. decreasing below to 60
℃
, system
will restart again. Other system would not influent by it.
T4,T3-1B and T3-1A: when the temp. sensor is detected to suffer open circuit or short circuit, fault alarm will occur.
2) Temp. sensor malfunction come out from main unit: main unit and all auxiliary are shut down.
3) Temp. sensor malfunction come out from auxiliary unit: this unit shut down, and all others do not affected by that.
11
Total water outlet temp. sensor of No.1 unit (Malfunction code E3), which only available for main unit, but auxiliary
unit.
Under cooling or heating mode, adjust it according to water outlet temp., the adjust range are: Load, stabilize, unload,
emergency stop
。
12
TBH1-A the low temp. freeze-proof sensor of No.1 unit.
13
TBH1-B Inlet water temp. sensor of No.1 unit .
14
1) Water outlet temp. sensor of No. 1 unit (Malfunction code E4)
2) Under cooling or heating mode, adjust it according to the unit water outlet temp..
Compressor adjusting range: ON and OFF;
15
Electric expanding valve B of No.2 unit
16
Electric expanding valve A of No.2 unit
17
1) High pressure protection and air expelling temp. protection in system A of No. 2 unit. (Protection code P0).
2) High pressure protection and air expelling temp. protection in system B of No. 2 unit. (Protection code P2).
3) Low pressure protection in system A of No.2 unit (Protection code P1).
4) Low pressure protection in system B of No.2 unit (Protection code P3).
Fixed speed compressor: Air expelling temp. switch connect with system high pressure switch in series.
18
Water flow detection of No. 2 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.)
19
Total water outlet temp. sensor of No.2 unit (Malfunction code E3), which only available for main unit, but auxiliary
unit.
Under cooling or heating mode, adjust it according to water outlet temp., the adjust range are: Load, stabilize,
unload, emergency stop
。
20
T3-2A of No.2 unit: Pipe temp. sensor of condenser A (Error code E5, protection code E6).
21
1) T3-2Bof No.2 unit: Pipe temp. sensor of condenser A (Error code E5, protection code E6).
2) T3-2A,T3-2B: When system outdoor pipe temp. T3-2A or T3-2B be tested by module electric control is over than
the protection temp. 65
℃
, the corresponding system would shut down, until the temp. decreasing below to 60
℃
,
system will restart again. Other system would not influent by it.
3) T42, T3-2B and T3-2A: when the temp. sensor is detected to suffer open circuit or short circuit, fault alarm will
occur.
Temp. sensor malfunction come out from main unit: main unit and all auxiliary are shut down.
Temp. sensor malfunction come out from auxiliary unit: this unit shut down, and all others do not affected by that.
22
T42 of No.2 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 T42.
