Re: Velux Window Openers - A Possible Solution

Can the Velux actuators be retrofitted? I was led to believe that they
couldn't be and that when one went wrong you more-or-less had to strip the
whole window out (frame 'n all) to replace it. Perhaps I was mis-informed?

What's the cost for a Velux actuator?

Thanks

Regards

Neil

I've just automated 6 windows and 9 blinds

Using the Velux interface

The windows open by brute force and close by the same system

I spent a long time looking for alternatives BUT in the end went for the
full Velux system



All of you who have installed Velux will know that

a)       its expensive

b)      it takes a lot of reading the pictures to install

c)       it works

My 2d worth

Hi Rob

The only reason I posted this was because I've seen many threads asking
about how to open Velux windows automatically. As I said, this is a
_possible_ solution, and one that I've not yet tried! I thought people
might
be interested rather than waiting until the later half of next year for me
to try them out first ;-)

However, the chap I spoke with at SE Controls was quite sure that the
actuators had been used successfully in many projects, both commercial and
domestic, to open and close Velux and Velux style windows.

Now I'm guessing here but it may be that you have to rely on the actuator
holding the window shut and in some way defeat the *horizontal bar* that
you
have, on a permanent basis. Nevertheless, it's a very good point and one
that I will look in to before buying any of the chain actuators.

As I said in the original post, Mingardi also make mag locks and catches
which may be of use to ensure security of the windows when they are closed,
although that does introduce a greater degree of complexity and cost, both
in ironmongery and controller I/O

The beauty of this idea, if it does fly, is for people like yourself, these
actuators are an easy retrofit (Once you've got the cable to the Velux!!)
unlike the Velux product.

My velux windows are also "automated" using a velux pole ;-)
How would these attenuators work as the operation to open my windows
involves the pull down of a horizontal bar before the window will tilt and
I
cant see how you automate that? Or am I missing something?

Many thanks,

Rob

I looked at motorising my Veluxes some time ago and abandoned the idea
because Mr Velux wanted an arm and a leg for each one and I have 6
windows.  Instead, I bought the manual opener  - a pole with a hook on
the end - and it works fine. Moreover, it shows that the operation
movement is essentially linear, and a DIY solution using an electric or
pneumatic actuator should be pretty easy to rig up (and not expensive).
One of the things on my 'to do' list once the house is finished...
