I've had a look at the wiring for the new thermostat. Currently my wiring is: Red - live Blue - neutral Yellow - switched On the attached wiring diagram, does this translate to L - red N - blue COM - yellow Is that right?

I currently have a Salus ST620 I think it's a S-plan. System boiler and unvented cylinder I've checked the wires at the existing thermostat and i have live, switched live and neutral.

I'm pretty sure it does have neutral. I'll double check

Hi, I currently have a wired thermostat which I'd like to replace with a wireless one. Do I simply swap the new receiver with the existing thermostat? The one I'm thinking of getting is this: https://www.amazon.co.uk/dp/B07HQD71YB/ref=cm_sw_r_apan_glt_fabc_C2EE4BQ8BHX3QZNZEWBE Thanks

Just to fully close this thread with an update: went through the Viessman fixed price repair route. The cost was £312 and they did replace the PCB. Boiler is working fine now :) He also confirmed that although the boards are used by both system and combi boilers, the boards are factory locked...

Rubber hose situation? What's that then? Does that affect my model which is the WB1C?

An update: he was trying to fit a second hand board (to save me money apparently. Funny how he said that as soon as I told him I'd rung Viessmann). Viessmann told me that the only way the value wouldn't change is if the board was from a factory supplied boiler. Anyway, I'm now getting a...

Yes he mentioned some sort of connection he had to make. What he was puzzled by was when it was flashing 1 on the display, he turned the left knob all the way right and said the numbers should go up but it stayed at 1. How would I tell if he's fitting a used pcb? He said the part was about 300...

No, he specialises in Worcheser Bosch and Baxi? boilers, although he said he's experienced with Viesmann

Hi, Can someone tell me if I need to get someone who knows viessmann boiler. Boiler not firing, Engineer says the PCB not firing because of FF error. He got a replacement PCB, tried to fit it today. Engineer says he can get into service mode, but not set the PCB to match the boiler model. It...

I went back and checked. It's defo the joint

Is it worth using repair putty or shall I just leave it to the plumber? Only reason I'm thinking of using putty is if plumber isn't immediately available

It's never cold where the pipe is. It's got a drip coming through now and then. I've not seen a joint like that before. Is it two pipes joined together, or is it a single pipe that's designed differently?

See attached pic. Pipe looks like its about to split? How has that happened? Didn't think pipes were joined like that? Going to get a plumber to fix it. Just curious as to what's happened.

Hi, Can anyone identify the block with four circles under the sensor? It's making an annoying buzzing sound apparently. Thanks

Get a carbon monoxide tester. It could be a prank, it could be something much much worse. Reminds me off this infamous Reddit thread. It was carbon monoxide poisoning...

Hi, I have a rather heavy gate that is leaning to one side. It has the Z sandwiched in-between. I know you can buy those anti sag kits, but I'm wondering if I can use a frame fixing screw (or equivalent) to drill through the post into the wall, and then tighten, which should move the post back...

Hi, I'm looking at getting a new shed installed. The current base is concrete and the existing shed is on bearers as the area can get very wet (lots of trees and foliage about). The new shed is on tanalised runners that will raise it 1.5 inches of the ground. Should I still put bearers down...

Hi, I have an existing shed concreted base that is 12ftx8ft. I'm planning on putting on a new shed that is 14ftx8ft. There's four flags laid to make the base up to 14ft in length (see pic). The flagstone that I've marked in red isn't quite level where it butts with the concrete. It looks like...

Hi, I'm trying to find a lamp diffuser for Waterline INTG cooker hood. Unfortunately all my searches on Google have been fruitless. Does anyone know where I can purchase one, or whether it's possible to buy a generic one and cut it down to size? Many thanks in advance LF
