I've replaced the variable speed fan control on our wood stove at least 3 times. The little unit is housed in the fan unit right under the front of the stove, and the heat it's subjected to causes an early death. I even put a thin piece of fiber insulation behind it the last time I replaced it, trying to shield it from the heat, but it still died in less than a year. So now I'm going to install a stand alone unit on the wall next to the woodstove where it won't be exposed to heat.
I bought a unit from KB Electronics, Model KBWC-16LK, as shown here. The wiring diagram is the bottom left one on page 2. I thought I was buying a two wire module, as shown in the top left drawing on page 2, but what I've got is the 3 wire one. The third wire (red) on the unit I have is connected to an "auxiliary" load. But I don't have an auxiliary load, just the fan, so should I just cap off that lead or should I connect it to the neutral wire coming back from the fan?
Thanks.
