Well i got this a couple of weeks ago for my veg room but there was no instructions with it

I'm basically wiring a 4 way socket into it so i can plug the fans into it rather than wiring the fans directly into the controller.

Heres a pic of the board inside

Now i think the Pe is the earth and the N and L to the left hand side are for the mains, but i'm not to sure if i just put the neutral and live for the fans into the N1 and L1 and use the same Pe for the earth as theres also the U and the N at the very end on the right but i think they may be for a switch to be wired in like a timer or thermostat possibly

So anyone know, Scrag are you there?

Anyone?

you tried there website?

http://www.ziehl-abegg.com/ww/fans-product-41.html

I did try the website but nothing comes up when i put in the code from the top of the unit.

I'm just wondering if maybe this isn't a ziehl-abegg, maybe its just been a controller of the same spec from some where else as Greens were having a little bother getting them the last time i spoke to them.

I think the is a case of Scraglor

I think i know but not willing to try it in case i fry a fan or something

U is your live out to your fan, N is for neutral to your fan. L1 and N1 are for 240v output when the thing is switched on, so for example you would connect a 240v lamp to these terminals that would come on only when the unit is switched on. motor terminals are labelled U and Neutral for single phase motors, or U V W for three phase motors

Hey well i've got another fan controller for my flower room, now they couldn't get the normal one so they got this big boy that was 6A still got it for the same price though.

Now i've got it wired and working fine but what i'm wondering is theres 2 connections on it that i'm wondering could they be used to switch it on to full power by using a thermostat or even just a timer.

Heres the wiring diagram, the connections i'm on about are the 2 on the far left that says underneath it "contact rating" and "230vac max. 1A"

Could this be used to switch it on to full speed either by a timer for lights on or even a thermomstat?

Cheers everyone (Scraglor)

alright mate. those terminals are for 230v "out". so when you turn the unit on, you get 230v at those terminals, like on the other one. you can use a thermostat,to switch over, but it's a bit (not too much though) more complicated. is it an electronic controller? or a transformer? (does it have stepped speeds or a continuous range?)

Hey mate thanks for popping in, its a 5 step transformer based fan controller, i wouldn't mind getting a thermostat wired up for through through the winter, what would be involved?

nothing too drastic. you want a non electronic thermostat that has both "call for heat" and "satisfied" terminals (satisfied basically means call for cooling), b&q do a bellows operated thermostat for about 10 quid, it's the lowest standard one they do. are you in the uk? either way, if you find a thermostat you think will do, run it by me and i'll check it.

U2 (feel sick just typing that!) should be linked to neutral internally. check this with a multimeter if you have one. just set it to ohms, it should read 0.0 or 0.1 ohms. assuming this is correct, you then you need to run U1 to the thermostats normally open output, or 'call for heat' terminal. then from terminal 1 (the 230v out) connect to the 'satisfied' terminal. there will be one other terminal that is common to the other two (normally your live input , but we're using it the other way round) that normally connects to the satisfied terminal, and then switches to the call for heat terminal when it gets to cold. from this common terminal, use the green earth wire (you dont need to earth a thermostat, so this cable is spare) and run this back to the controller, this is your feed to your fans L terminals, use a bit of choc block to connect it to the cable you're going to supply your fan with. and connect the neutral from your fan to the number 2 terminal (again, the 230v output) connect the green earth wire from your fan, to one of the earth terminals on the left of the diagram
