Wireless receiver relay connections

Options

Are there any connections on the wireless receiver that I can use to switch my circulation pump according to the heating requests? Can I have a wiring diagram for it?

What does Heating circle setting mean on the wireless temperature sensor and how is this connected to the wireless receiver? Is it an identification number for the 1st/2nd heating circle or I just set it to 2 when I have 2 circles?

What additional devices should I buy to handle the 2 circles with the 2 pumps? I now have 3 radiator thermostats, 1 wireless temp sensor and a wireless receiver.

Are there any usable documentation about these?
