Got a 2 speed fan. 3 relays.
I wired it so that an adjustable thermostat gets acc power and triggers a relay for the low speed fan. The second relay is connected to the AC compressor. The third relay is wired normally closed in between the thermostat and the low speed relay. It is connected to the AC relay so it should open the 3rd relay and not have both fans running at the same time...it doesn't work.
