“Can this unit be used with a variable speed A/c, blower and Furnace? Its a 4 wire connection, but not sure if that still allows control of variable speed?”

• Yes - just read the wiring guide or give Ecobee a call when you install. This unit does allow Rh and Rc separate inputs.

• Variable speed fans are typically controlled at a hardware level by the furnace and the ecobee is unlikely to be able to do more than on/off.

• The ecobee web site has a great compatibility checker. I would recommend going to the site and answering their wiring diagram questions at https://www.ecobee.com/compatibility/
