How do I install my new Filtrete 3M-30? I only have 4 wires..B, W,, G, R
You might try the HVAC forum, very helpful to me.

I am sure someone here knows the answer, but the guys over there do this all the time. Most thermostats are installed by plumbers and AC guys.

I used to do plumbing work, but it was a long time ago and I don't remember the common color codes now.
