Hi. As speed controller I use toroidal transformer with 6 output. It gives 90,110,130,150,180,210 voltage. I can change speed by multi point switch or by relay. The motor doesn't make hum.

Can only find 2 output down here man, the company that makes this controller i have has another one with power failure memory function, the only way for me to get the one i have with power failure memory is to design a circuit and i know nothing about circuit design.

The company that makes this inline fan & brand this controller say to me i must wire all 4 terminals on the controller but they arent sure if this will give it a restart memory, im not even sure if that shit works ! i dont know, maybe it turns out it shocks me and fucks everything up, never know with fucking chinese people who cant speak english : / Anybody using a kb electronics controller ? Peace

I tried a temp based on off with a variac, it worked for the temps fine, but my RH got way to high. I then wired in a duo stat controller that gives me an on at specific temps or RH settings.

The downside is that it is on or off (not low or high) so no negative pressure when off.

Yeah ive made a list of a few controllers that i can acquire now, just about some decisions to make, i made a forum post on some electronic forums asking if its possible to add a simple circuit to allow it to have a memory, another thing i stumbled across is the wiring of the controller, as you can see there are 4 terminals, and on the backplate of the controller it states i must wire 2 terminals but i emailed the fan company and they said i should wire all 4 terminals as in live & neutral from the mains on the 2 left terminals and the motors live and neutral wire into the 2 right side terminals of the controller , now im pretty scared too do that, i dont know what to do, what if they just stupid and it blows my controller or fan up : / then im really screwed but yeah i think i just better get a new controller ?
