When the ensuing mess ups happen to the instrument, it can be that your sensor is broken) The water temperature displays E1, EE, 00, ninety nine or -- or the water point and water temperature jump randomly) The water point gentle is off or all on; the water point does not drop or drops rapidly or rises quickly; the water level mild displays up and down, but would not show in the middle) The water point is displayed, yet there isn't any water within the water tank. There is a giant error between the displayed water temperature and the actual water temperature. 2. How to come to a choice a 2-wires or 4-wires sensor?1) Cut off the sensor sign cable. If there are 2 wires, want a 2-wires sensor; if there are 4 wires, choose a 4-wires sensor) Observe the quick plug of the software sensor. If it is a 4-pin and 4-hole connection, choose a 4-wires sensor; if it's a 2-pin and 2-hole connection, select a 2-wires sensor) Observe the indoor instrument. If the instrument sensor has entirely 2 screw interfaces, then it is going to solely be related to a 2-wires sensor; if the device sensor has 4 screw interfaces, then it is a 2-wires and 4-wires general-purpose instrument, please persist with the original selection. 3. How to do the wiring?Adjust the substitute to the 2-wires position, and connect the sign wires to "red" and "yellow" in keeping with the color. If the show is abnormal, change the wiring positions.
