electrical window wiring/control

[J.C.E]

Doing a rewire of a kitchen where the exisiting electric windows are remaining

The previous controller/connections was cut out and thrown away with the builders demo!

Never really had to connect up a electric window before- I have extended the 2x 2core cables the go to the 2 windows- with a 5core into a cupboard that I can get power from via a 13a spur to fuse down...

But what gear do I need and what are the connections to power these windows again and control them
The client is happy with a standard switch- or the lighting is controlled by Lutron RA2- so if I could control it by this too that would be a nice touch

see photos of cables coming from 2x windows attached..

How were they previously switched? I would expect to see a 2way retractive switch for open and close or some form of remote control.

If you've not already done so, check if the actuators are 230V or 12/24V. Some models come in both a 230V and a lower voltage variant. You wouldn't want to get this wrong!

Im assuming they are 12/24v as the only cables that go up to the 2x windows are 2x 2core cables

so do i need to take a 6a 230v feed into a 230-12v transformer then the positive 12v into C of a 2way retractive switch then both of the reds into l1 and both of the whites in l2 but then how is the window actuator getting a N/negative 12v??

I remember seeing some type of bulking box (tranny possible) but this got cut out and thrown by builders!!

If they are DC swapping the polarity will open/close the motors. There is no point in guessing though, the first thing you need to do (after punching the builders) is get the details off of the window motors.

You need the details off the window motor. If they are 24v DC, You can check the window motor functions properly with a 18v Drill battery.

The actuators work with a 12v driver

when 12v polarity is correct (+ of driver to + to windows they open)
Then the windows close when i reverse polarity (+of driver to - to windows)

is there a user friendly switch or remote/receiver setup i can use to do this reverse polarity switching for the windows to be open and closed by the client

Need to investigate where the limit switches are and how they are wired.

 

[freddo]

If there is only 2 wires to each motor the limit switches will be built in.
