Notices:
1. When the following failures occur to the instrument, it may be that your sensor is broken.
1 The water temperature shows E1, EE, 00, 99 or — or the water level and water temperature jump randomly.
2 The water level light is off or all on; the water level does not drop or drops rapidly or rises quickly; the water level light displays up and down, but does not display in the middle.
3 The water level is displayed, but there is no water in the water tank. There is a big error between the displayed water temperature and the actual water temperature.
2. How to choose 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, select a 4-wires sensor.
2 Observe the quick plug of the instrument sensor. If it is a 4-pin and 4-hole connection, select a 4-wires sensor; if it is a 2-pin and 2-hole connection, select a 2-wires sensor.
3 Observe the indoor instrument. If the instrument sensor has only 2 screw interfaces, then it can only be connected to a 2-wires sensor; if the instrument sensor has 4 screw interfaces, then it is a 2-wires and 4-wires general-purpose instrument, please follow the original selection.
3. How to do the wiring?
Adjust the switch to the 4-wires position, and connect the signal wires to
