The Coal-trol Digital Standard or Standard+ would be appropriate. Standard+ gives you the Energy Star thermostat (4 weekday and 4 weekend setpoints, vacation hold). Standard has all the same features and capabilities except only two setpoints and no permanent/vacation hold.
We sell a plug kit for the CM2-4 that you can use to get your motors wired up for use with the Coal-trol. We highly recommend separating the combustion and stoker motors, though the Coal-trol can be put into "triburn" mode to work with a one plug stoker/combustion installation.
Give us a call at 315-299-3589 if you have any questions or when you are ready to buy. You can also order online at our website, http://www.coaltroldigital.com
