Dynalite is only sold through installers who have been on training, that is why you won't find any pricing. The USB interface is used for programming using DLight and now Envision which replaces it...

10K linear pot is fine but you'll need a 10v regulated supply, dimmer works on principal of 10v = 100%, 5v = 50% ,etc. so unless you want your lights to dim and down randomly you'll need a regulated...

As an owner of a Part P registered installation business I would suggest you go down the notification route for a one off job. In other words you notify building control that you intend to do the...

With a ground source heat pump it isn't always better or necessary to control the individual zones like you would with a boiler. Heat pumps seem to work better when they run at a pretty constant...

I didn't take it as a personal attack...

What you have created is central controller talking to some dimmers, that is no different to the theatre environment that DMX was aimed at. You have...

As the author of the reply to toscal's original question I have to say that Gangsta's comment that part of my reply "is quite wrong" is actually not true! He has got round the limitation of DMX in a...

Oh yes should have mentioned - the main difference between a 100 and 200 is the weather compensation and better controls - the 200 is worth the extra

I have a Vitodens 200 with Vitotrol 300 remote with weather compensation. You won't need to control it, set up the times you need heat, target temperature in the house and experiment with the weather...

I'd stick with good old mains! The new Philips Master LED GU10 7W is very impressive and part of a whole range of LED lamps, mains in and dimmable with normal leading edge dimmers. That said they...

Comfort can be bought from www.smartalarmshop.co.uk, they don't do PIR's as you can use any wired PIR's, just about any bell boxes, etc. It does do both security and home automation very well and can...

Not tried them but this is the only one I've seen - http://www.justhdmi.co.uk/acatalog/4_in_8_out_HDMI_Routing_Matrix_over_UTP__cat5e_6_.html

Will be using their 4 x 4 shortly so will let you...

Bandwidth isn't the issue, it's physical channels that is. Digital audio is a single phono connector, stereo audio is two. Balluns are simple devices, they take an unbalanced signal and balance and...

We use Component matrix switchers all the time, however what you require is a component video and digital audio matrix switcher which severely limits your choice and I have never seen anything like...

Having worked in the theatre lighting industry for far too many years before starting my own company installing home automation I hope I have a good understanding of both?!

DMX is a way of...

The advice given on T5 fluorescent tubes is not to dim them within the first 100 hours of use.

Most LED's can be dimmed but not using a standard dimmer. LED's can be dimmed using pulse width modulation, i.e. a constant voltage switched on and off at high frequency, decrease the 'on' periods...

How about the Orchid 308 Analogue PABX ? Around £140 for a 3 line 8 extension PABX, more than just an intercom, it's a complete phone system. Uses normal phones, simple to program, plugs into BT...

We recently completed a large KNX installation of 150+ lighting circuits, 28 zones of UFH, DMX colour change LED's, etc. This involved over 100 devices, which is only practical on a bus system, (100...

OK so here's my opinion, (for what it's worth!)

Ethernet will not be the solution, but it will be part of it, building control needs relaible, low bit rate communication over an open cable...

According to KAT5 website the RGB versions don't pass audio

"KAT5 Custom Modules

Also available are the AVTX-RGB and AVRX-RGB units, which are suitable for carrying high quality RGBS signals to...

MK make such a plate in their Edge range, two twin 13A sockets plus Euro module "holes" - just add the right number of euro modules, cat 5, Coax, F connector, etc.. They call them Combination plates....

We are currently working on a project that will involve many velux windows and we are interfacing them to a Dynalite control system. This is how I understand it - you will need a WLF111 per set of...

You're welcome

I will be on the Ivory Egg / EIB Shop stand on Sat & Sun at the Smart Home Show, if you're there on either of those days come a long a say hello.

Yes you will need to test all...

Not helpful I know but from experience of several of these devices the answer is run a cable! I've never yet had satisfactory results from these.

Installing a control system is very different from normal electrical installation and involves far more than just an understanding of what each component does.

My advice would be get a control...
