When the resultant failures occur to the instrument, it can be that your sensor is broken) The water temperature displays E1, EE, 00, 99 or -- or the water point and water temperature jump randomly) The water level gentle is off or all on; the water level doesn't drop or drops quickly or rises quickly; the water point mild reveals up and down, but doesn't show in the middle) The water level is displayed, but there's no water in the water tank. There is a big error between the displayed water temperature and the particular water temperature. 2. How to make a decision a 2-wires or 4-wires sensor?1) Cut off the sensor signal cable. If there are 2 wires, select a 2-wires sensor; if there are 4 wires, desire a 4-wires sensor) Observe the fast plug of the tool sensor. If it's a 4-pin and 4-hole connection, choose a 4-wires sensor; if it's a 2-pin and 2-hole connection, choose a 2-wires sensor) Observe the indoor instrument. If the software sensor has only 2 screw interfaces, then it'd solely be associated with a 2-wires sensor; if the gadget sensor has four screw interfaces, then it's a 2-wires and 4-wires general-purpose instrument, please stick to the original selection. 3. How to do the wiring?Adjust the change to the 2-wires position, and connect the signal wires to "red" and "yellow" according to the color. If the show is abnormal, switch the wiring positions.
