Wiring a Thermador Hood
Remodeling my kitchen and bought a used Thermador 48" hood with a VTN600q dual blower, to go over my 48" rangetop. There is no model number I can find on the hood but believe its around 10yrs old. Its in great shape.
I need to wire it and wanted to run a dedicated 3 wire circuit from the mains, however the hood has 4 wires, white, black, green,red. I bench tested the hood connecting to 110 V AC using only 3 wires, (not using the RED), all functions worked perfectly, (two lights with hi and low option, two heat lamps and a variable speed knob on the big blower). Not sure what the red wire is for? Perhaps a remote blower set up? I hate to wire anything and have a spare wire hanging out there. Do I need to wire this differently that I am thinking? What am I missing?
