AC 220V Multifunction High power Automatic Liquid Level Controller Module Water Level Detection Sensor

The product is based on detection of water tanks (water tank) water level to control the large current relay to achieve control. Small size, simple wiring, low power consumption, large switching capacity, strong anti-interference, high functional stability. Can be stable to achieve the pool (water tower) automatically open when the water pump pumping, pumping to full stop automatically when the pump. and many more……
 Product Specifications:
       Supply voltage: AC 220V. (Or 380V)
       Control output: Current 0 ~ 30A (high-power relay)
       Control power: 0 ~ 2.2KW (theoretical maximum can control 3KW).
       Board size: 10 * 6.6 * 3.2cm
             Net weight: 0.15KG
       Shipping list: level control circuit board * 1 (not equipped with the probe line and accessories)
   This product is not what the so-called special probe
   You can not need to purchase a separate probe, with home wiring can replace the probe.
Note: The so-called probe is a wire with a plastic net shell to buckle up, with a home wire can be directly sensed, the thread stripping more than 5 cm, making it a bare wire can be directly induction. For more durable recommendations contact with water thread end contacts stainless steel.
Controller wiring instructions:
1, the single control on the pool (that is, pumping) Probe Installation Installation diagram as shown:
On the line - for the upper pool (water tower) level control point, the water level up to (S) point of water, water and probe contact, the water level controller automatically shut down the pump;
The water level drops below (Z) point water level, the water and the probe disengage, the water level controller automatically opens the pump, the pond water-filling;
Offline - for the pool (water tower) on the lowest point of the pool.
Note: In the bottom of the pool probe (S Z) to short.

2, the single control of the pool (ie, drainage basin) Probe Installation Installation diagram as shown:

     (Upper S) point, the water contact with the probe, the water level controller automatically open the pump, the pool drainage; on the water level control point,
     The water level is lowered to (Z) level, the water is disconnected from the probe, the water level controller automatically shuts down the pump, and the pond stops draining water;
     Under - for the sink ground wire, on the lowest point of the pool, the pool group is not connected
