2.1 Function description
1. The hydraulic module board and external kit simultaneously output the open/close of port of TBH, IBH2, IBH1, AHS, SV1, SV2, SV3, PUMP_O, PUMP_D,
PUMP_C, PUMP_S, P_X.
2. The hydraulic module board and external kit are both tested for AD values of port T5, Tbt, T5_2, Tw2, T1, Tsolar. If neither the hydraulic module board nor the external
kit has collected the set active sensor parameters, the hydraulic module board reports a corresponding sensor fault.When the hydraulic module board and the external
kit simultaneously collect different parameter values of the same sensor, the hydraulic module board parameter values shall prevail.
3. Disconnect communication with the main control board for more than 1 minute, the hydraulic module will shut down and output an EL fault, and the fault display on
the wire controller.
4. Connection for other components see the “INSTALLATION AND OWNER’S MANUAL” of indoor unit.
