I replaced my trusty of old basic electric Potterton Kingfisher with a

However, I miss having the external programmer of old - if I wish to
switch things off when going away etc it means going to the boiler itself.
Viessmann reckon the way round this is to use an extra external controller
- using the room stat circuit - and leave the internal one set to
constant. Which isn't really what I want. Apart from the unnecessary cost.

The integral controller has a four pin plug for everything - so I'm
assuming DC and a data circuit. Any reason why I shouldn't just extend
this and site the programmer where I want it - the cable run would only be
a metre or so. Or any other suggestions?

Other thing is the existing old programmer is mounted on a tiled surface
and if I remove it it will leave holes. And I've no spare tiles. But
dislike having an unused device left in place.

Hi

You need Part No. 7133 385 according to the installation manual. This
is a wall mounting adaptor plate for the controller and includes a
blanking plate for the front of the boiler.

Maximum cable length is 30M and you need 2 core cable apparently.


Spoke to Viessmann this morning - what a breath of fresh air getting
straight through to a bloke who obviously knew the things inside out -
when asking for technical advice.

The part number you gave is correct for earlier units but it seems can't
be done with current ones. What they do supply is a slave unit which looks
the same and duplicates all the operational features of the main one which
stays in place - all it doesn't do is allow access to maintenance and
setup codes/features.

It does indeed work on only two wires and it's a Vitotronic 300 with a
part number 7248 907 - this is for the weather compensated one.
