I am trying to control a pair of ceiling fans using SA UFR modules. The problem that I have encountered is that the UFR cannot start the fans if they are manually set at any one of the 3 speed settings via the pull chain.
If I set the fan to OFFf with the chain, the UFR clicks in and gives me the green led . I can then manually start the fan at any speed with the pull chain. If I try to start it at any speed setting other thatn OFF the UFR may or may not click and then gives me a combination of green and red leds.
Once the fan is running, the UFR will turn off when it is supposed to. I thought it might be some kind of weird inertia problem when the blades were completely stopped, but even if I try to activate it before the fan blades have slowed down, it still will not engage.
This is happening in 2 different rooms with 2 different UFRs on 2 different links.
Jim over at AO thinks that there is a conflict between the UFR and the electronic speed controller in the "cheap" fans, and suggests using a fan that has a seperate winding for each speed. I doubt my customers want to chuck a couple hundred dollars worth of fans to experiment with more expensive ones.
I read the thread for Aug 15th about just using a standard UPB switch to control the fans programmed as a simple ON/OFF switch with no dimming (I do have a spare 1130 on my test bench) but then what the heck is the UFR supposed to be for? I thought is was supposed to BE a relay module.
Has anyone experienced this in their installations?
