dikki Posted August 16, 2004 Share Posted August 16, 2004 Hi all, not being electrically minded at all, would I be able to use an immersion heater timer controller? seen them advertised for about £20+vat specs below (from Maplins) Operating voltage: 230Vac 50Hz Switch rating: 230Vac 13A resistive or 6A inductive Operating temperature: -10°C to +50°C Dimensions: 115 x 74 x 50mm Surely I could just wire the mains plug in 1 end & the lamp directly to the other? please let me know asap, as I can get a lift there today & if I can't use it I'll try to muddle through the build as I don't know any sparkies!! dikki Link to comment Share on other sites More sharing options...
Guest RAZ Posted August 16, 2004 Share Posted August 16, 2004 I think there's a few peeps that don't use contactors, a mate of mine has never used one, he uses heavy load timers cost about £10-15 each. Never used a heater timer so can't comment on that, Nigfis built my contactor by following this thread ...... Elzzar Link to comment Share on other sites More sharing options...
Guest nigfis Posted September 17, 2004 Share Posted September 17, 2004 So now we have the home-made contactors, I wouldn't mind using mine to turn the heater on when it turns the lights off. Looking at the relay, it shouldn't be too hard.... Anyone done this yet? Link to comment Share on other sites More sharing options...
Welsh man of the valleys Posted September 28, 2004 Share Posted September 28, 2004 You missed the post you want about 3 pages back, on turning one off and one on Link to comment Share on other sites More sharing options...
Guest nigfis Posted September 28, 2004 Share Posted September 28, 2004 You're right, Welsh man of the valleys. By feck, that's a long name. Welcome, by the way. Anyways, I had missed the diagram. Cheers for that. Link to comment Share on other sites More sharing options...
Redseal Posted November 13, 2004 Share Posted November 13, 2004 eBay's worth keeping an eye on for relays for those wishing to build a contactor. They tend to go cheap as there's little demand for them these days.. I picked up a 10A one plus base for 99p.. bargain Link to comment Share on other sites More sharing options...
growguy yorks Posted November 25, 2004 Share Posted November 25, 2004 just a crazy idea,but how about wiring a small 15w lamp between neutral and pin 5 of the relay,put the light outside the grow room so you have a visual indication of when its dark.Also as a rough guide if your unable to obtain the start up current from the manufacters, multiply the lamps wattage by 1.8 and use this figure to calculate the current rating required 91344[/snapback] I know what time my lights go on and off, as im sure every grower does, i mean, those timers dont set themselves now do they m8, , ur toke m8, there u go. enjoy Link to comment Share on other sites More sharing options...
Bond Posted December 23, 2004 Share Posted December 23, 2004 Hi, I am going to build myself one of these, i will try to build it so that it turns my heater on (as described earlier in this thread). I want to make sure I order the correct parts as I am pretty clueless with this sort of thing. I currently have a 400HPS, but i will shortly be adding a 250MH, what Relay switch would you recomend, will 10a be enough? A link to the actual item on maplin etc would be great, as i said i am useless at this so need to be hand fed a bit to make sure i dont blow the house up!!! Thanks for your help!!!

Blimburn Posted March 16, 2005 Share Posted March 16, 2005 i think a 30A relay would be better i thought a 10 amp relay is only 1amp inductive Link to comment Share on other sites More sharing options...
BushDoctoR Posted April 11, 2005 Share Posted April 11, 2005 whats up peeps?? i have built this contactor and it is having problems turning off it has no problems switching when there is no power to the lights, but when the lights have been on it wont switch off inside, the relay looks like its trying to switch but cant its wired correctly, and it is not a dodgy relay cos we bought another one with no luck it wont even switch 1x400 let alone the full 2x400 & 1x600 that we need to run we are running the 2x400 & 1x600 through a 10a mcb with no probs so surely the load couldnt be the problem for the 10a relay, right????? can anyone help please?? i guess theyll have to be turned off manually for now >B-Dr< Link to comment Share on other sites More sharing options...
