I just purchased 3 Caframo Bora fans for my Catalina 350. I was impressed with the low current draw in the specs-- only 0.2 amps on high, and they are quiet. They were installed in two existing lighting circuits of 15 amps each, consisting of 10 AWG wire. The peculiar thing is that these fans use some type of electronic speed control rather than a hard switch to change speeds. If any light on the circuit is switched on while a fan is running, the fan shuts down. It will restart and run normally by pushing the button on the front of the fan again, regardless of what other loads are on the circuit. This circuit is lightly loaded to begin with. This wouldn't be a huge deal except that if I get up in the middle of a hot night and switch on a light, the fan in the guest cabin will shut down and no one would know until they woke up in a sweat.Has anyone else had this problem or know of a work-around?
