Cannot get this fan with speed control working at all.

[TheConduitKing]

Hey everyone. Got a head scratcher for wiring a fan with a speed control with a run on timer on site today. I, and two spark could not get it working at all. We wired it according to how we think it must be done according to the wiring diagram supplied. We can get the fan to turn on. But no speed control from the wall mounted controller. Any help at all would be greatly appreciated.

I’ve included pictures and links that I hope will explain better than I can and be clearer. Any questions just ask away.

This is close to the the wall mounted controller installed on site. Same brand.

Does the fan speed vary when you alter the potentiometer that's on the board

From memory I think it does. But I'm not 100% sure. I'll try that in the morning

Actually. I think I might have figured it out now from reading the manual again. It states that for external speed control a jumper needs to be removed and I see that we still have it in place on the board.

I'm thinking that might be why??

Exactly

Update. Did it this morning. Removing the jumper got the on off button on the switch working but the speed control doesn't work. And we have to short out between L and T on the run on timer to get it to work in non-resetting mode.

Can you post a clear diagram of how you have connected all of these components together, then we may be able to see what's going on.

I'll try and do a rough diagram here. But we have just connected it as shown in the diagram pictures I linked in the op
