Thermostat/Control box help

[Riley]

You posted a danfoss wiring guide which doesn’t open. Is that for your existing wiring centre or what is required for the new. we’re really having to drag the info out here

Sorry. If I knew it didn't open I'd have explained more right, yeah it's a danfoss wiring centre WC4B, going to 2 separate danfoss HPA2 valves, with 2 thermostats which will require mains voltage to them. Just in case you need it the boiler is a Ideal Logic Combi ES35. I believe the wiring station isn't configured correctly, or is only done to the minimum needed for the existing setup as the existing thermostats are only battery powered. The house is a fairly new build and there are short cuts everywhere. I'll try and upload the wiring diagrams again.

Yes, that is the existing thermostat, being replaced.

 

[Adamh2009]

This is what is being installed, but the gas heating version. I'm aware that is the electric heating version.

Then you need to find the other box as I have previously said which will be 240v

It's not the wireless model so there is no other box is there?

 

[Harvest Fields]

You said that it had batteries in?

It does, but it's not wireless! This system is a right mess isn't it? That's what's installed as standard by barrot homes!

It’s a low voltage. Battery in thermostat two wires to centre but it’s not right

So should the brown wire be giving a voltage? Also, do you know which configuration I need to wire up for the new set up?

 

[Riley]

Right let’s start this again. The link you posted DOESNT work so we can’t tell if it’s for the old set up or the new. Do you have two zones and a hot water cylinder?? If you do it’s SPlan plus. We still need to know what the new stat requires wiring wise not just that it requires 240v it’s not just as simple as running 240 up a cable it’s how it all links in. Did you test the existing with a multimeter or a volt stick

 

[Harvest Fields]

I would want a pro in to sort that out mate.

Right, for the new set up I have a logic combi es35 boiler, a danfoss wiring station WC4B, two danfoss HPA2 valves and I will have two Bht-6000 thermostats that will need a 240v feed, an earth and the 2 control wires.

You can post that link all day long and harp on about the wiring centre, but in the real world it mean absolutely nothing mate. You may need a complete new wired system or just new supply. But without a pro looking at it you may never get it to work. On that note I’m out.

 

[Riley]

As above mate. As I said it isn’t just as simple as getting a voltage up the wire it’s subsequently integrating it into the system to work correctly

That link is to download a pdf that has all the different combinations for the wiring station. It does do 240v to a thermostat, but I'm not sure which diagram I need to use, once I know which diagram is for the new set up I'm fine. Just can't wrap my head around it. So my wiring station will work and valves etc... Just need to know how to reconfigure it.

I’d say 2 in the guides best suits

Thank you, as I was leaning towards 7.

However I’d be more inclined to contact danfoss and ask for a wiring diagram to suit a 2 zoned combi set up
