Moved into a new home and I would like to move up to the Learning Thermostat. The current setup is a heat pump with backup electrical heat and dual zone control. (2 thermostats - 1 up/1 down) It is a Lennox system from @ 2004 with the Harmony II zone controller. Equipment model numbers and thermostat wiring below. Is there any way to wire this up to a Learning Thermostat without replacing the existing equipment? I was thinking the * terminal may a solution because I have an O and B on the existing, and obviously can't shove two wires into one terminal on the Nest.
Thanks,
Brian

Hi OsterfeldBJ,
Thanks for reaching out here in the Google Nest Community.
With the kind of HVAC system you're using, it is recommended to have a Nest Pro or your local HVAC technician to install the Nest Thermostat for you.
