From your experience would swapping the main panels generally be straight forward? Going to take the lid off this weekend, on the old one. Have the installer code, was given it when the fitter moved, so will stick the panel in installer mode. Was planning on taking pics of the old board and...

Thanks. Seems so. Strange considering when I had this original alarm fitted, their Scantronics brand seemed to be really popular. Anyhoo, would you know anything about the internals on these panels?

Hey, Thanks for coming back, and glad you managed to sort your issues. I’ve been reading through those heat geek references in your last post, and some really useful information there. - Thanks for that link. Reading your experience from my non plumbing experience perspective, it seems a...

I have an I-on 50EX panel and I need to upgrade it to support internet access/ alerting / control. My home phone provider is ceasing my telephone line. Unfortunately the guy that fitted the system has moved overseas and the few local guys I’ve contacted haven’t been particularly interested in...

Hi Berty, How did you get on with this? My radiators are also around 5 degrees between Flow/return, and I think I’ve read the same guidance as you on this site about adjusting the lockshield valves to achieve a dT or 12 while also running at around 60 boiler temp. Not sure where to go from...

Hi, Whats the difference between the VR920 and VR921? I’m looking to add internet control to my 700. Also which is the best Vaillant app or can you use any of them with these controls? Vaillant’s website isn’t too clear on this. Thanks Nathan

Not sure I can completely retire the heatmiser to be honest, based on the boiler schematics in that document from Vaillant. As I understand it, Vaillant don't have any UFCH controls to manage the actuators on the manifold so that at least would remain. The boiler schematics on pg 28/9 (see...

Anybody have any insights to share around this? Been looking at the installation / Wiring Guides from Vaillant and think page 28 is the closest fit for my scenario. Can anyone share some insight on the specific wiring of the relay to the heatmiser?

hello all, I have a 3 bed home with UFCH downstairs and radiators upstairs. I have an ecotec plus 624 system boiler and currently all my controls are the older heatmiser prt/ts type. I have 3 seperate thermostats, the first controls the upstairs radiators, and two downstairs controlling...

Hi All, just thought I would follow up on this to close the thread. Had my original installers in today, and after they finished laughing, when I told them that to get hot water I had to run the cold tap, they spent about thirty minutes running between the loft and the bathroom. The...

Thanks Dan, I'm sure they are ok - I believe they are a legit operation, but never heard of G3 before - will be checking though :) thank you.

Hi Gazza, All the taps and showers are mixers in the house, and this problem is right now effecting every tap. If this is a problem with a single mixer valve - that would only affect that tap - not the rest in the house - or would it? About testing this - I can give it a go now - If i...

Hi Dave, yep, i will be calling in the guy who initially installed the system. - What's the G3 ticket you mention? Not heard of that before? How do I check if the guys that did this originally have that ticket? or if not, how do I find one that does have that ticket? Any reccomendations for...

Thanks Dave, Will take a look tonight in the loft. On the whole though - I'm guessing this looks to be a problem with the plumbing rather than the boiler - correct? If its the plumbing, I should be calling out the plumber, not the boiler manufacturer's chap. THanks for all your help

Hi Gas, thanks for the reply - not sure what a prv is - primary return valve? (what's one of those?) All the taps in the house are mixer taps, and the same scenario applies to any of these. On one tap I have to turn on the hot, and at another, the cold to get hot water out of the first...
