Does anyone know of a suitable 4 pole isolation switch for use on a zone valve in a domestic environment???
But only 3 going in, or maybe not I suppose depending on the setup.its a normal 2 port heating valve, permanent live, motor live and neutral, switch live to boiler/pump etc, - 4 poles???
a 3pole 'fan' switch would do, if you isolate the permanent live then the switched live is by default also isolated,its a normal 2 port heating valve, permanent live, motor live and neutral, switch live to boiler/pump etc, - 4 poles???

I thought that but if you have multiple valves in parallel (as per standard S plan) the 4th pole would need switching, depends on the OP's application.a 3pole 'fan' switch would do, if you isolate the permanent live then the switched live is by default also isolated,
it would indeed, had a brain freeze. Switch live would be isolated. Thanks guys :Salutea 3pole 'fan' switch would do, if you isolate the permanent live then the switched live is by default also isolated,
something like this

The switch lived (orange) would become live when another zone calls for heatit would indeed, had a brain freeze. Switch live would be isolated. Thanks guys :Salute

i have just drawn out the wiring diagram and i do need 4 pole isolation, second zone valve would power up orange on first one.but would it,?
as per Lurch,
what exactly is your purpose/reason for needing it isolated?
I don't know of any domestic looking 4 pole isolators, but you could run the orange return wires to relays. this would allow you to isolate the valves from each other on the returns and use 3P isolators.i have just drawn out the wiring diagram and i do need 4 pole isolation, second zone valve would power up orange on first one.
I have been asked to install it for isolation/maintenance on a Vaillant VRC system. It's in a big mansion house and i wanted something 'domestic' looking, any ideas???
beaten by Lurch,I don't know of any domestic looking 4 pole isolators, but you could run the orange return wires to relays. this would allow you to isolate the valves from each other on the returns and use 3P isolators.
so use the oranges from both valves to pull coil on two seperate relays??I don't know of any domestic looking 4 pole isolators, but you could run the orange return wires to relays. this would allow you to isolate the valves from each other on the returns and use 3P isolators.
if only it was a simple straight forward customer! :facepalm:could you not hide the switch somewhere?
I cant think of anything 'domestic' looking,
apart from a rotary isolator,
its going to involve contactors I think, unless someone else has an idea.
beaten by Lurch,
I type slow...... :C
Exactly. Only needs to be something small stuck in a box, something like the Omron MY2 range.so use the oranges from both valves to pull coil on two seperate relays??
Problem is that's a bit fail dangerous. You are relying on the relay energising to isolate the supply, unless I have misunderstood what you are intending?I would have the relays/contactors permanently 'n/c' [use double throw] and only energise the coils when the isolator is off,
that way less energy to burn out the coil,
