Sorry, for the delay. Busy days lately!
Yes, it is that simple. When you get it, read through the manual and make sure to set the MIN and MAX setting in the SETUP menu to the recommended settings for your brand of stove (listed in the manual). This should get you up and running pretty well. As you get familiar with the stove and burning coal you can tweak the MIN and MAX to get optimal burn out of your stove. But as far as the day to day and hour to hour operation of the stove, the thermostat will control the feed rate, the combustion fan, and the convection fan to keep the temperature where you set it. You just keep filling the hopper and cleaning out the ash pan.
