W-2WAY ECO-i SYSTEM
Control Functions
This system contains 2 types of pressure sensors: a high-pressure sensor and a low-pressure sensor.
(1) High-pressure sensor failure
Alarms are emitted when the high-pressure sensor becomes an electrical open-circuit or a short-circuit condi-
tions, and a broken wiring, short-circuit or poor connection to the PCB in the high-pressure sensor circuit.
(2) Low-pressure sensor failure
Alarms are emitted when the low-pressure sensor becomes an electrical open-circuit or a short-circuit condi-
tions, and a broken wiring, short-circuit or poor connection to the PCB in the low-pressure sensor circuit.
