Am doing a bathroom reno and installed a new fan. Original switch was a simple on off single pole. I want to install a DewPoint condensation fan switch that will turn on automatically at a certain moisture level.
The new switch as 4 wires. green ground, red fan, black power, and white neutral. I know the ground, but how do I hook up the neutral and fan to the existing fan set up?
There is a double pole light switch in the same box that has a couple wires to it, and there is a mass of whites that I am not sure where they go
Can I hook up the neutral somewhere else, or put it with the fan like a single pole? What do I do with this?
In the attached picture the switch on the right is the 2 pole light switch and on the left is the fan switch that I hope to replace.
