I recorded a video… in this video it shows 3 fans. These are Hunter Gallegos AC fans, and have no pull chains. The speeds are operated completely by Inovelli VZM35-SN wall switches. The switches are set at “low” (33%) speed.

The fan in the front is by itself on a switch. You’ll notice the speed. All single fans in my house that are tied to a switch, are running at this speed.
The two fans in the back are tied together, being controlled by a single switch. You’ll notice that the double fans are running slower than the single fan. In two places in my house, I have this two-fan on one-switch setup, and in both places, the fans run slower. To test, I disconnected one of the fans, and the other fan ran at normal speed. It’s only running slower when two fans are connected to the single switch.
Is this normal?
