Hello, I have a toggle switch/on or off switch that delivers power to the hunter ceiling fan. I control the fan speed and light on the ceiling fan. The wall switch has a ground, neutral and hot wire. I purchased a lutron DIVA DVFSQ-LF which has a hot wire (red) which controls the fan, yellow which controls the light, and green wire (ground). So, I have 3 wires on switch side and 4 wires on the lutron side. Maybe I can do away with one wire but I am not sure. Please advise.THanks !
