The answer to your last question is : Yes
When you have decided on which timeswitch, thermostat and cyclinder stat you are going to use, let me know and I can do a wiring diagram for you.
Good luck

I will be using the Sunvic Select 207XL programmer, Sunvic SA 1452 cylinder t/stat and the Sunvic TLX 4101 room t/stat. The 3 port valve is standard colour wiring I assume so wouldn't matter which I bought.
I would appreciate any more help with a wiring diagram as you suggested previously.
Many thanks, John

As you are using Sunvic parts, here is the URL of the Sunvic wiring diagram for a Y Plan (they call it Unishare, but its the same thing) I suggest you print it off for reference.

I take it you do not have an Apollo Timer/Selector. But if you do, just disconnect all the wires from the timer 6-way plug to the Terminal block
The main changes are to the pump and boiler wiring.
1. The boiler must have a permanent supply to it: this is shown as the dotted line from terminal 1 of the junction box. It goes to the Mains L terminal in the boiler.
2. The pump should be connected to the Pump L and N terminals not to terminal 9 as in the Sunvic Diagram.
3. The only other connection to the boiler is from Sunvic Terminal 8 to the ON terminal on the boiler (this is the one next to the Pump N)
There should be NO connections to the boiler HW CH or CH OFF terminals and NO link between HW and ON.
The link from Sunvic Terminal 8 to 9 to 10 are really superfluous. The boiler is actually fed from terminal 8.
Just so you don't get confused, the Apollo Y plan wiring diagram I posted earlier assumes that the Apollo Timer and Selector is being used.
