volt free wiring on y plan

[trevthelec]

hi, I have ariston boiler with volt free connection ,ta1, this should have been plumbed with 2x 2 port valves as recommended by manufacturer , but plumber has installed 3 port valve so we have to put relays in can anyone put me in right direction with wiring from wiring centre to relays?

Does the valve and boiler not come with wiring diagrams?

Instead of wiring the boiler the SW,n& earth go to the relay.

hi judd , only for 2x2port which I get, not for y plan with relays

Connect the orange of the valve and normally closed of the cylinder thermostat to one side of the coil, neutral to the other side of the coil, one side of the TA1 connection to common of the relay and the other side of TA1 Connection to normally open of the relay.

If you get an 8 pin relay base connect orange and normally closed of cylinder thermostat to pin 2, neutral to pin 7, one side of TA1 to pin 1 and the other side of TA1 to pin 3.

Can’t you use the auxiliary switches on each valve,these then connect to boiler connections.

It’s a Y-plan not a S-plan.
