So in answer to the question, yes Parameter A does exist on the HRE SB although it's not mentioned in the manual. In fact there is a lot not mentioned in the manual. However with following setup it's possible to get a W Plan working, in this case with a Nest: Parameter 1 =1 (Heating and DHW...

Ok, so I'm assuming that it's Parameter A that provides the option. But is this available in the SB version?

It could by using a relay, but can the boiler itself be setup that way using a parameter?

I have a question regarding an Intergas system boiler. The boiler has the ability to control a diverter valve using pins 5 and 6 on X2. The normal mode of operation is to open the diverter valve to Port A for CH. Can the boiler be configured to open the diverter to Port A for HW? So that with...

Go ahead and I'll see if I can answer.

Updated schematic with larger text:

I'm struggling to upload a the latest revision of the schematic because the resulting image quality is so poor.

I assume your open vent version doesn't have a pressure switch that cuts the boiler if the pressure falls below around 1 barg. In my case I do and that is simply a open or closed contact across terminal X9, pins 5 and 6. I also wanted to stop the boiler in the event of the condensate pump...

What energy source replaces gas?

It's taken well over a year for me to get around to drawing this up, but I thought it might be useful for others to put down on paper my setup for an Avanta 18S boiler with an unvented cylinder and iSense RF. I've based my diagram on those provided by Remeha for other systems. The key...

The Rapido T valve is very well engineered and way better than a lot of the shiny 'designer' s**t that you can buy. Google RB Supplies and it should be fairly obvious what plates go with the valve. I found them helpful.

Can you give some examples of modern, ie. 17th edition installations in which supplementary bonding would be required?

Supplementary bonding is not earthing. The objective is not to create a new earth path because that is what the earth in the mains cable is doing. Linking all the pipes to the gas pipe might make it a 'better' earth than the cable and I don't think that is a good idea. The objective of...

By definition does a stub stack ever have an AAV fitted? Para 1.30 of Part H suggests not and if doesn't comply then it's not a stub stack. You still need to keep the level higher than the max basin level, but a cap is less bulky than an AAV.

The Kudox controller turns off after 2 hrs and the Tesla controller returns to whatever it was doing beforehand; that's the difference. They both control up to 800W so 80W is OK. The IP rating of the Tesla controller is better, IP55 versus IPX4. However if the element is only 80W then...

More info on the Toolstation one here although its actually made by Tesla UK Ltd I think the Tesla one allows you to leave the heat on at one of five levels or just boost for 2 hours and then off (or back to what it was doing before boost). The Screwfix one doesn't judging by the reviews. I...
