Sunvic TLX RFP replacement

[Conor O'Nolan]

I have an installation with TLX RFP but one of the receivers (2 zone system) has failed. The Rx has 3 connections, L,N and output which goes to a zone valve (and via that to boiler).

I may have bought the wrong replacement which is TLX 6001RFPv. It's receiver has 5 connections as you can see from diagram below. I'm assuming that this is intended for direct connection to boiler, but this won't work for me.
So, I wondered if I could modify to use the relay to feed Live to the output? I hope the attached diagram illustrates what I'm thinking about.
