The mechanical just has the 2 wires. All the Tstat does is connect(close) the 2 wires to make a circuit back to the furnace. So, just replace with another Mechanical. Digital units will require extra wiring you will not have at the existing tstat. Doug
Hate to disagree with you Doug but I installed a simple digital thermostat in my 2003 Yuma. It's self powered with an internal battery and all that connected to it were the 2 wires that were wired to the original bi-metal thermostat.
