Regarding the incukit xl heater: which wires do what? I would like to use it for a homemade incubator that already has a temp controller. What kind of power supply does the heater and fan need? 110 volt?
There are four wires for this unit. The ones coming from the heating element are typcially red and blue. The ones for the fan are typcially both brown. Both the heating element and fan operate on 110v power.
