Thermostat replacement We have a Bryant Plus 95s Evolution running with a Trane TAYSTAT 340 thermostat, the installer said the 3-Stage 355CAV thermostat would be an extra $500 so we passed. I don't think the Trane thermostat allows the Plus 95s furnace to run efficiently? I think I should replace with a model SYSTXBBUID01-B Bryant thermostat, can I do this myself or do I need a Bryant installer?
