Wiring problem 2 zones pumps + salus it500

[razvan_rich]

Hello!
Please help me!
I have a thermostat salus IT 500 and it300, Ariston Genus One 35kw and 2 pumps for 2 heating zones.
What I want: to independent control each zone, floor no1 and no2, with the pumps. When the temperature that I seted up reaches, the thermostat to command a pump to close the circuit.
Problem: I can't make the wiring system.

You will require two single Pole contactors

Simply

Lne to stat
From stat call goes to a1 on contactor a2 neutral from stat / same circuit
Then a perm live to one side of the contactor from the same circuit
The other side to the pump

Hope that makes sense

I need E type. Right?

Yes .
But as long as you have two motorised valves. If you only have two pumps, you will need to fit relays, to stop the boiler getting a back feed.

Pumps = valves maybe????

Stat won't be rated for the pump amps so could blow / damage it
