OCC Posted March 4, 2006 Share Posted March 4, 2006 (edited) Relay and base came today. Hopefully will have a go at hooking it up later. Just a quick question, is it ok to use 3A 3core cable for my fan? (safety first) Edited March 4, 2006 by OCC Link to comment Share on other sites More sharing options...
bren Posted March 14, 2006 Share Posted March 14, 2006 right if i got a had a cintactor with a co2 unit in one side and this fanspeed controler insteda of lights on the other would it work ok, with co2 first coming on 1hr after lights then releasing enough for the room then 10-15min later fans come on for 15min the nswitch off and enough co2 relesed and repeated until lights off, would this work ? to control enviroment and co2.

OCC Posted March 14, 2006 Share Posted March 14, 2006 can't quite understand bren, my relay works a treat and everything is working now, I also got an enclosed waterproof electrical box to put everything in, along with cable glands etc. Just waiting till i feel a bit more awake till I do it all, been really busy with rl shit. I was reading it's ok to use 3A cable for the fans, only reason I was asking was because of the inductive(sp?) load. Link to comment Share on other sites More sharing options...
Guest Bluntdawg Posted March 20, 2006 Share Posted March 20, 2006 If you wanna save yourself the bother of making 1 of these look for a seller called sparky4uquads on ebay. He knocks these together for a reasonable price. I paid just under £60 for a humid/thermostat with day & night settings & a 4 gang socket. Link to comment Share on other sites More sharing options...
OCC Posted March 20, 2006 Share Posted March 20, 2006 Well true but honeywell thermostat and fan speed controller and a digi timer are only max 30 quid and simple to wire Link to comment Share on other sites More sharing options...
Guest Bluntdawg Posted March 21, 2006 Share Posted March 21, 2006 Turned up today.My dads a sparky so im gonna show him this to see if he can knock a couple together for my homies & shit. Well worth 60 notes & i didnt av to get my hands dirty. If i leave feedback i also get 12 months warranty. Put that in ya pipe & smoke it. The box on top is the dial to set the humidity & the digital box is to set the temps. Sweet as a nut m8. sweet as a nut. Link to comment Share on other sites More sharing options...
arthur lee Posted April 10, 2006 Share Posted April 10, 2006 Nice thread oldtimer1, thinking along the same lines as yourself here's a post I put in earlier this year This picture shows an evitomental control board for a 21 light set up. All 21 lights are controled on a single time clock (5) and switched via 2No. 4pole 25Amp contactors (2). The intake and extract fans are controled by a thermostat (9). When the temp reaches 25C and above the fans run via a contactor (1) at 100%. When the temp drops below 80F the fans are swithed to another cotactor (7) and this in turn can be adjusted from 80% to 20% depending on the outside temp via a speed controler (4). When the lights are off the intake and extract run on 20% and the heater circuit is then enabled. This again is set at 21C via a thermostat (6) and switches 2No. 3Kw via a contactor (8). So that the system doesn't overload, a photocell was added (10). This stops the lights and heaters running at the same time. The whole system is fed on 25mm / 100Amp cable (11) direct from the mains and is distributed via a standard consumer unit (3). All these parts were obtained from a local electrical wholesaler for under £300 apart from the speed controler which was supplied with the extract system. Hope you find this intresting Love Arthur Lee 1 Link to comment Share on other sites More sharing options...

neuromancer Posted April 20, 2006 Share Posted April 20, 2006 Wow Mr Lee! I too am deeply impressed! Please, please furnish us with a wiring diagram and perhaps a list of suppliers! It makes my hotch potch of fans, timers, contacters and heaters look a bit pale (and rather frightening!). Link to comment Share on other sites More sharing options...

BL Posted June 12, 2006 Share Posted June 12, 2006 Hi I'm using this diagram kindly provided by OT1 to build my fan control but I'm wiring up an intake aswell as an exhaust. I'm not sure whether I need to wire both fans directly into the thermostat, or use some sort of a splitter on the cable coming from the thermostat going into both fans. Any advice would be greatly appreciated. BL Link to comment Share on other sites More sharing options...
compostverte Posted July 19, 2006 Share Posted July 19, 2006 if you're in the UK, B&Q have most of the parts. Link to comment Share on other sites More sharing options...
compostverte Posted July 19, 2006 Share Posted July 19, 2006 Thanks for your reply.I've just realised I have two fan speed controllers already running my fan, so do i just need a crossover relay as the light relay in the diagram is the timer, is that that right? yep - Maplin will have the relay.- but what you could do is buy a room thermostat instead.
