Harman Automatic Room Sensor Temperature Control

The automatic temperature control uses a room sensor which is
is hard wired to the stove and can be extended to any point in the room.



Combined with the exhaust sensing probe thermistor (ESP) the control board
constantly monitors and adjusts the appliances auger speed to maintain
heat levels to within 1 degree Fahrenheit at the location of the room sensor.

This is far superior to the often arbitrary location of a conventional thermostat on a wall.
