Plumber struggling with vr66 install vaillant

[Phill Peck]

Thank you all for your responses.

I spoke to vaillant advance. He went through a few d.7 settings which basically specifies the set up of the cylinder(3 port , 2 port , s plan y plan etc). And now it works.

He said this boulder does not need zone valves . And the boiler man could have plumbed it in a less labour intensively way.

Did anyone else mention that throughout this thread

FFS so is it actually working now ? It is , then it isn't then it is

FFS Bernard stop digging and your arguing about an appliance you barely know about

It should work if you take out the two MVs, take out the VR66, wire the VR10 correctly and set up the cylinder re HW priority....

D.07 what's all that about?

about an appliance you barely know about

The boiler I will accept that my knowledge is limited,

Two wire power and data bus design is something I do know about having used / developed more than one version over the years. A system similar to the bus promoted by Karl Dungs ( a German manufacturers of heating systems was already being used in England at the end of the 1970's.

The non polarised version allows for less than competent installers to screw up the polarity and not damage the modules.

the problem is bernerd your generalising , you have engineers ( the bunnies ) who know these boilers inside out and you've read there post as a sweeping statement and still try to prove your statement right . your statement is right in a GENERALISED situation thou .

but what i do think is that the OP is full of it TBH and i reckon he's doing this job himself either as a DIY or its a plumber out of his depth

 

[bernardgreen]

the problem is bernerd your generalising

The basic laws of science are generally applicable to all things technical

you have engineers ( the bunnies ) who know these boilers inside out

how often does this inside out knowledge owe more to the marketting hype for the boiler and less for a scientific appraisal of the boiler by the installer ( applies to all makes and too many expert boiler technicians.

Ok. My boiler man has offered to remove the zone valves. Is this worth it?

 

[picasso]

is it really working or you still having problems ?

 

[Phill Peck]

Let's assume everything you've posted is true and correct!

In which case it now works.
Don't let the guy who doesn't understand it near it again.

When a zone valve fails whenever that may be. Find someone who knows these controls to remove both valves and rewire correctly.

I can't see how the zone valves can fail as they've been manually opened....

I thought it was all working correctly now.

If set up right the vr66 will power open the valves will it not?

 

[Steelmasons]

Well it's not working as it should is it...
