This is an automatic control box originally for 240V/50Hz single phase submersible pumps.

The controller automatically controls the pump motor as well as providing comprehensive pump protection and phase failure protection. It works in either auto or manual way.

The box are metal casing, comes with 6 water probes. It is compatible with all 4-wires deep well pump in the market that required a capacitor to work.

Among these 6 probes, 3 are for monitoring the well's water level (up, mid and low) and the other 3 for monitoring the storage tank's water level. You can bypass either monitoring or both to just use it as a manual control box when needed.  With the automatic box installed, the pump will turn on and off automatically according to the water levels of both the tank and the well. This is extremely  important for using it in a well with only limited water supply, as the pump only should be operating when it submerse in the water to get enough cooling and lubrication by the water going through it.

If turn control switch to “manual”. The control box will works like starter box.

It can be installed at indoor or outdoor.
