Remote Control Linear Actuator and Pump

How to Control Opening Roof and Water Pumps together

Question from customer:

I have a project to install 1 linear dc actuator to control my opening roof and 2 small water pumps. So I need to control from a remote. Both pumps need a remote switch for either on or off; 1 actuator needs a remote switch to up and down.



We recommend you 2 motorized remote receiver (S2U-DC12) and 4 button transmitter (CV-4). 2 receivers are connected to linear actuator and water pumps’ motor respectively. You can use one transmitter to remote control them easily. This kind of remote can control Lights, Motors, Fans, electrically operated doors / locks / windows / blinds / cars or other appliances with AC110~240V or DC0~28V.

You can turn on/off the receiver with transmitter (remote control) from any place within a reliable distance; the wireless RF signal can pass through walls, floors and doors. The working distance is about 500m.

We have made a presentation to show you how to install and operate.

We prepare the following material.

2×2 channel receiver(S2U-DC12)

1×4-button transmitter(CV-4)

1×linear actuator motor

2×dc motor

DC 12V power supplies

Some lines

Here is the wiring for linear actuator.

Here is the wiring for dc motor.

One receiver is connected to the linear actuator, the other is connected to 2 dc motors.


We set momentary mode for linear actuator controlling and toggle mode for small motor because they only need to be switched on and off. It won’t generate interference for each other, even though we use the same transmitter to control 2 receivers.

Switch on power.

22U-DC12 &CV- power on

Press and hold button 1, the linear actuator moves forward(stretch out). Release button, it stops moving.

2S2U-DC12 &CV-4 button 1 stretch

Press and hold button 2, the linear actuator moves backward(draw back). Release button, it stops moving.

In a word, press button 1 and button 2 can make the linear actuator to reciprocating movement in a straight line. The opening roof  can be open or close through its reciprocating movement.

Press button 3, turn on motor 1. Press button 3 again, turn off motor 1.

Press button 4, turn on motor 2. Press button 3 again, turn off motor 2.
