My parents currently have a mercury thermostat (Carrier T864R1384) that they want to replace. What would be the model of choice for them if they were looking for the easiest to install? Thanks, any guidance would be greatly appreciated!
T86R sounds like a specialty tstat. Do they live in a condo or have hot water heat? Need to know what type of heating system they have and how many wires the tstat has. Post make/model and serial # if you can.
