I have a pump that supplies my farm with water. The motor on the pump is 3.7kw and is 3 phase power. The pump fills a 5000 litre tank which lasts about a day. The on-off switch is roughly 400m away from my house (no line of sight, lots of trees in-between). Would I be able to connect it to the switch so that I can switch the pump on and off from home 400m away?

With external extended antenna, this remote control unit can be long range controller. Transmitting distance is about 2000m. How to remote control 3 phase power water pump? Besides the transmitter and receiver, we should prepare a relay which is applied to the pump.
Step 1, the relay should be connected to the receiver. Then three live wires are connected to the relay and 3 phase power supply.
Step 2, another three live wires to connected the relay and water pump.
Step 3, power to the receiver. Pressing the big button of the transmitter, the receiver will receive an “ON” signal to instruct the reply and pump to work. Pressing the small button of the transmitter, the receiver will receive an “OFF” signal to instruct the reply and pump stop working.
