Connecting a wireless thermostat to a glow worm boiler

[mark bowen]

Yeah lol, a 240v supply and a N/O contact. Rocket science.

Not after step by step advice just a pointer in the right direction

All the advice we can give you we already have mate without giving you step-by-step instructions.
You have all the info you need.

No worries . Seems this forum is more about an ego boost for the members more than anything else . atb

Has it been completed eg commissioned then ?

It's building regs so doubt it was signed off

You need to be gas safe to wire in that thermostat so best get him back or another one in

Providing you don't break a combustion chamber seal you can remove the cover of a boiler, and from what I understand there aren't many boilers in the UK where you would need to break a combustion chamber seal for wiring purposes.

You unit is going to need a power supply (line, neutral and earth). Regarding the link in the boiler (that you've shown in another picture) connect 3 and 4 on the new device to the terminal block with the link in it (removing the link as you go) and you should be good to go.

I might be inclined to use some 5 core cable (custom made you might say for this as you can use brown, blue and yellow/green for the L, N and earth). You should sleeve the conductors you use to connect the link terminals with brown tape.

Actually, scratch the brown tape, just re-read the picture... the thermostat connections in the boiler are 24v so don't need it.

If you don't fancy doing it, PM me, I'm just down the road in Marshfield.

Thank you I appreciate that

Ahh.. ok, sorry confusion... thought the pic was from your boiler but clearly not. Need page 12 of the boiler manual by the looks of it.

Can’t seem to find page 12 that tally’s up

Bottom right of page 14 in that file you linked above... Conditions for 230v controllers. Sleeve cores with brown tape (at both ends) and connect as shown in that diagram to terminals 3 and 4 of the thermostat receiver and you should be good to go.

please read it again carefully as the seal is the cover,

only time you or the customer can remove the cover is when it a Decorative casing: These cases can usually be removed by the consumer e.g. can be lifted off or are
hinged panels and do not need to be unscrewed.
