Hi StokerInPA,
First off, we don't really offer the Advanced or Advanced+ anymore. We haven't updated the website yet to reflect that, but so few of them sold compared to the Standard/Standard+ models that we just couldn't justify keeping them going. As it is, we can provide a modified version of the Standard to provide you an interlock circuit and/or the aux output (which were the main features of the Advanced vs the Standard), so when you're ready to order you can call the shop to discuss custom options to the Standard/Standard+.
The difference between the Standard and Standard+ is only the thermostat model. Standard comes with a 2 setpoint thermostat (day and night, same settings used for each day of the week). The Standard+ comes with a thermostat with 4 weekday and 4 weekend setpoints. Otherwise the units are the same.
The Standard or Standard+ will work with your installation. If at some point you want to add the use of a furnace blower with your coal stove, we can discuss options for modifying your Coal-trol Digital Standard or simply adding on an independent temperature limit switch to control the furnace blower.
We encourage you to call us at 315-299-3589 to discuss your installation and how the Standard would be wired in to meet your needs, and then hopefully to order.

Sincerely,
Paul
