set up nest thermostat

[Rich6]

i have seprate heating and cooling units wired to 1 thermostat. i need a rc and rh terminal on the thermostat. i have plenty of experince with this kind of system.  is there a sub  base available with rc and rh or do i need to install an isolation relay to seperate the 2 power sources.

The Nest Learning Thermostat, 3rd Gen, is the only Nest thermostat that supports having an Rc and an Rh terminal.
