We've been asked to control a Big A$$ Fan, Isis model. There is a 0-10v module that replaces their wall controller/remote. You lose some functionality since the remote will allow 21 speeds, but we're fine with the ~10 speeds available via the 0-10v.
My question is, since this is the only 0-10v device in the project, is my only option to add the TVM kit and GRX-TVM2? I'd like to be able to keep position8 open for other future use and the cost is a bit high. Is there any way to do this externally? I'm assuming the GRX-TVI won't work since I don't have a 0-10v source from the BAF module? (see attachements)
Thanks for any thoughts
You could use a unregulated 10v power supply/ Transformer and run that off homework's dimmer. When I did it I ran it from a rpm so you might not meet min load and need a synthetic load. It must be unregulated. I have done that once before when i was in a jam. I don't recommend this way but it does work.
Great, good news - but what do you mean by "the LUT-Box as an interface"?
thanks
If I recall correctly and it has been a couple of years now that the BAF has a constant hot and a control wire. It is the control wire we ran through the LUT-Box synthetic load.
I can't see why a grx-tvi wouldn't work, provided you can sacrifice a dimmed rpm circuit in the project and don't mind it being displayed as a light in any GUI.
