• LJXH 2 Wires Bottom-mounted Water Temperature Water Level Sensor 3/4 Inch SUS Sensor Probe Suitable for Solar Water Heater Specifications:Product Name: 2 Wires SensorWater Level Wire: RedTemperature Wire: YellowSensor Length: 30cmSignal Cable Length: 50cmConnection Size: 26mm (3/4") Internal ThreadOperating Voltage: 220VMounting Method: Bottom-mountingSensor Material: Stainless SteelPackage Contents: 1 x sensor Notices:1. When the following mess ups happen to the instrument, it can be that your sensor is broken) The water temperature displays E1, EE, 00, 99 or -- or the water level and water temperature bounce randomly) The water point soft is off or all on; the water level does not drop or drops rapidly or rises quickly; the water level soft displays up and down, yet does not demonstrate in the middle) The water point is displayed, but there is no water within the water tank. There is a giant error between the displayed water temperature and the actual water temperature. 2. How to make a decision a 2-wires or 4-wires sensor?1) Cut off the sensor sign cable. If there are 2 wires, choose a 2-wires sensor; if there are four wires, choose a 4-wires sensor) Observe the quick plug of the tool sensor. If it's a 4-pin and 4-hole connection, choose a 4-wires sensor; if it is a 2-pin and 2-hole connection, prefer a 2-wires sensor) Observe the indoor instrument. If the utility sensor has only 2 screw interfaces, then it might only be connected to a 2-wires sensor; if the utility sensor has four screw interfaces, then it's a 2-wires and 4-wires general-purpose instrument, please keep on with the unique selection. 3. How to do the wiring?Adjust the switch to the 2-wires position, and fix the signal wires to "red" and "yellow" in step with the color. If the reveal is abnormal, swap the wiring positions.
