I love my heater booster now!!!!
I have four relays, so that I can independently control the circulation pump, the interior fan, the Espar enable line, and the ignition-is-on line. It is controlled by an Arduino and the enclosure is 3D printed at the local makerspace. A menu system lets me select between always-on mode, timed mode, and engine-heat-only modes. Thermostat control will be going in later.
The controller leaves the circulation pump on for 60 seconds after I turn off the heater. I think this is important because the heater still is burning residual fuel.
