Vaillant latest 470f WC controller with latest ecotec 831 boiler

[chris watkins]

Can I ask, is this a replacement boiler installed on to an existing system ? Is there no chance of you getting the installer back to sort out these teething problems did he suggest the WC or did you ask for it ?
I am sure it all just needs tweaking & once working it will reduce your gas bills.

No its a brand new Ecotec boiler and we are pleased with it , the installer suggested the weather controller and I am sure they are just teething problems, I have been in touch with the installer about turning up the boiler and removing the stat on the radiator but he doesn't think this is the problem. I have emailed vaillant but to no avail.

I know the boiler is new but were the rads replace ? If they have not been sized to suit a water flow temp of 75 deg C then this could also be leading to the sort fall. Get them back as others have said. The curve can be changed & by the looks of it there is also a pre-heat option that can be applied to get the system up to temp on the first on but all of this is engineers mode.

Hi I just got through to Vaillant and they said that the heat curve should be on 2.3 no more,by putting it on 4 it could overshoot the requirement or something. I have tried to adjust the boiler to maximum using page 13 instructions as above but it won't go above 75 deg.vaillant have said that I need to try it tonight and if no improvement they will send an engineer to check the settings they were very helpful actually,so far the temperature on the controller has gone down not up! What a nightmare.

no offence but your installer is in the wrong, the stat on rad will conflict with your controller, and the temp on your boiler can be adjusted to max temp flow which is 80c but needs to be done by an installer. where are you ? put a post in the plumber wanted forum on here, someone may be local that can do this for you

Great news I finally got through to Vaillant and they were really helpul.They confirmed that the boiler must be set to max and they are sending an engineer out no quibble.We are under warranty.The guy said that many installers are not setting the boiler to max and this is causing problems with the controller.Believe it or not I live in the town where the boiler is made so the engineer won't have far to come, I have a list of questions for when he gets here..Thank you both for all your help, I will post again when he has been in the hope of helping others.

Great news! But make sure you make him a cup of tea before you bring out the list!

Yes I'm good at tea and lists,just not so good at central heating controllers!

I offered to write an article about WC heating system controllers for this forum, based on my own experience with it and lots of research into heating curves etc.

I sent a draft to Dan a few weeks ago for approval but have not heard from him since.

If you pm me with an email I could send you a copy of what I've written so far.

Hi stratobuddy,

are you able to share this document? Or post it somewhere on the web where I can download it?
