Joint hogger Posted February 16, 2016 Share Posted February 16, 2016 mate, what version of the 8" fan do you have, the A or L version ? 1 Link to comment Share on other sites More sharing options...
Secret-squirrel Posted April 13, 2016 Share Posted April 13, 2016 I thought I had replied to this Thanks chaps it's all wired correctly and working (sort of). For some reason the t6360b thermostat keeps kicking the fan in at around 18-20 deg? I've tried turning the temp to '0' and then up slowly, but the fan keeping kicking in to full speed around 20 deg. And I've set the temp to 28 deg, but the fan goes full throttle as soon as I switch the variac on? Any ideas guys? I'm going mad. Oh yeah I'm using 3 core but have read and followed the instructions on here, I've also tried wiring the t6360 with terminal No.4 instead of No.3, but that makes the fan run on full power until I turn the thermostat dial past the current room temp.

Secret-squirrel Posted April 15, 2016 Share Posted April 15, 2016 I could really do with someone knowledgable seeing this, I'm in need Link to comment Share on other sites More sharing options...
Joint hogger Posted April 16, 2016 Share Posted April 16, 2016 it might be because your using 3 core cable, ideally, you should use 4 core cable with the T6360. 1 Link to comment Share on other sites More sharing options...
Secret-squirrel Posted April 20, 2016 Share Posted April 20, 2016 (edited) it might be because your using 3 core cable, ideally, you should use 4 core cable with the T6360. So I just need to earth it?

Have I got this right your variac works when you go past the max temp and full power when it,s below min temperature?

CaptainStoner Posted July 17, 2016 Share Posted July 17, 2016 (edited) Do variacs (ravistat 2f-1 type) need to be in a metal (grounded) housing? I've got IP60-something rated plastic housings for mine - wondering if the variac frame needs to be earthed or something like that connecting live neutral and passthrough for output earth i got no problem but i worry that the frame of the variac and thus stuff close to the bakelite dial i turn is live Edited July 17, 2016 by CaptainStoner Link to comment Share on other sites More sharing options...
Joint hogger Posted July 17, 2016 Share Posted July 17, 2016 no it doesn't need to be in a metal housing tho you DO need to wire the earth to the mounting bracket on the variac, here's a few pics to show you how to do it. - - 3 Link to comment Share on other sites More sharing options...

ursus1000 Posted July 23, 2016 Share Posted July 23, 2016 You can of course buy enclosed variacs,so need to sort a box for them. Link to comment Share on other sites More sharing options...
SamBell Posted September 14, 2017 Share Posted September 14, 2017 (edited) On 27/02/2011 at 3:01 PM, SexiSarh said: As promised guys the photos of my finished: Thermostat controlled, 2 speed fan controller - You can set one dial to 40% for example and if the GR gets hotter than you have set your thermostat, then it switches to dial 2's setting e.g. 70% to cool it down then switches back to 40%.So to summarise, parts were easy to source, putting everything together was a dodle the only stumbling blocks were the wiring for me and not knowing the correct thermostat to buy so my points of advice for others would be. Make sure the Thermostat is a SPDT (Single Pole Double Throw)- I went through 4 Thermostats trying to get the right one! I have made some notes to the OP's wiring diagram (I mistook the Power in for Fan socket power!) - Bloody stoneres! Just a note my Thermostat has 5 contacts (That's why I have 4 cables leaving the box) 2 go to the Thermostat) My Live went to Output in the end and my Neutral to Input - Not sure why but otherwise 0% was full and 100% was no power??? Anyway apart from the above minor hitches I really enjoyed making this and think it will improve my GR greatly. https://www.uk420.com/boards//boards/uploads/monthly_02_2011/post-59510-0-42242300-1298818879.jpg My Klimavator conked out recently and am going to build a dual variac, thermostatic controller. It seems though that most designs use a relay, but this one does not, the last picture in the above[1]. The relay is accommodated by the thermostat itself, I think. Is this right? Sexisarh had all sorts of problems, including smoke, so just want to make sure [1] This editor just is not working, can't get images to post it seems. This might work?
