Can I use the Wireless Receiver to JUST control the HW and CH pumps?

Hello community! I would like you advice on using the Wireless Receiver to turn on and off the two pumps I have to control the hot water nd the central heating. I am on a district hearting system and therefore have no boiler. At the present time I just need to control the pumps using the app. No temperature adjustments (this is still done manually by the values on the incoming communal heat).

Hope you can help me on this one.

Richard :-)
