I removed an old ceiling light/fan fitting. There were 4 wires coming out of the attic into this old unit: copper, red, black, white.
I have a new light/fan combo to fit. It only has 3 wires: green, white, black.
How do I join these?
Then for the wall switch:
There used to be 2 switches; one for the fan, one for the light.
The new wall switch is a single unit with a light button and a fan button on the front. There are 3 wires coming out the back; green, black and white.
How do I wire the wall fittings?
Many thanks if you can help.
