 Same issue here. My old Lennox iComfort 10F81 is toast. I would like to replace it with a Nest Thermostat. Is it possible??

I am still trying to find information on wether I can install the Nest Thermostat Gen 2 on the Lannox XP25 Heat Pump. I think I can, it will just take rewiring the thermostat wire on the inside units circuit board.
