deanbo Posted April 5, 2006 Share Posted April 5, 2006 I need a speed controller/s myself for my rvk 150 and 125 fans,with a view to adding the thermostat in the future. Trouble is my local B+Q is crap and might not have these things,as it doesn't stock the majority of what other poeple have bought from their local B+Q's. If they do have them what kind of amperage are we talking about ? 1 amp ? It sounds to me like a heavy duty dimmer would do it if B+Q have them as a previous poster said his was just a dimmer when dismantled. So what sort of power handling capacity will this dimmer need to have ? thanks. Link to comment Share on other sites More sharing options...
TightBud Posted April 5, 2006 Share Posted April 5, 2006 its been said b4 dimmer switches work but can be noisy(buzz) which some people dont like a lamp "has nothing to run" a fan has a motor thats why its best to use a fan switch£12 b+q Link to comment Share on other sites More sharing options...
deanbo Posted April 5, 2006 Share Posted April 5, 2006 Thanks but unfortunately my local B+Q doesn't sell that or snything remotely like it either,just on/off lighting switches and some cable is all they have for sale. As i said my local B+Q is crap and very expensive too. Who else sells these things ?[not online]. Link to comment Share on other sites More sharing options...
prawn Posted April 7, 2006 Share Posted April 7, 2006 I made one of these a few months ago exactly the same as Raz's However my fan comes on full speed when the temp drops I have wired it up just like raz's photo, which is a great help Do i need to change the wires round on the thermostat? To get it to turn fan on when temp rises. Cheers Hi, I've got the same problem, I've wired it up exactly as per Raz's instructions, taken it apart wired it again checking everything, but it still only kicks in full speed when the temp drops below the chosen point anyone got any ideas why this is happening ?

prawn Posted April 7, 2006 Share Posted April 7, 2006 this is driving me mad, I've been at this since I got home from work @ 6.30 The only thing I can think of that's different in my setup than from Raz's is that I have an earth on my fan, I've just cut and taped it so that it's out the way and the same as Raz's photos, but I'm wondering wether to wire it up to the other earths in the junction box?

prawn Posted April 7, 2006 Share Posted April 7, 2006 Right, just totally undid everything and tried oldtimers way of doing it but it's still only kicking in full speed when it drops below chosen temp , not above. So it must be something with the wires, I've just had a thought about electricity always going the easiest route, maybe it's something to do with the cable I'm using, does it have to be the same thickness for all the connections? (controller to stat, stat to mains, etc.) or am I barking up the wrong tree? Is there a way of switching wires to make the stat turn off instead of on when dropping below chosen temp? christ, £80 isn't sounding so bad for a fan controller now Link to comment Share on other sites More sharing options...
oldtimer1 Posted April 7, 2006 Share Posted April 7, 2006 Changed my mind on the drawings, I have changed them back. This will reverse the option to the above diagram, but its not correct I think.. prawn I had to get a stat out to test it. If you turn the stat to high or max the stat is switched to say the room temperature is below the set point, so 1 and 4 are open and the dimmer will be in working mode. If you turn the stat down until it clicks 1 and 4 closes and the stat is in the position where the room is warmer than the set point and the fan will go full speed as the switch is closed across the fan controler terminals. Make sense? Link to comment Share on other sites More sharing options...

skerbalrat Posted May 7, 2006 Share Posted May 7, 2006 Changed my mind on the drawings, I have changed them back. This will reverse the option to the above diagram, but its not correct I think. Ahhh why won't it work? I have tried Raz's method and also using oldtimers, but the fan still kick's in when it gets cooler. And also: It's a honeywell T6360B1028 Been trying to get this to work for a long while and i want to start growing again, but cant until i get this to work Link to comment Share on other sites More sharing options...
skerbalrat Posted May 7, 2006 Share Posted May 7, 2006 Just trie d swapping the connections for pins 1 3 and 4 around. Dunno if this was safe? Maybe my thermostat is buggerd? On the above diagram my thermostat shows pins 3 and 4 the other way round. But i have tried swapping the connections. Please help Link to comment Share on other sites More sharing options...
