The RT-08 OS Grafik II controller is a combustion optimizer with a dark function display. Designed for furnaces supplying duct accumulation systems, for operating Zdunskie stoves, fireplace insert with heat accumulation, as well as traditional fireplace inserts equipped with direct air supply to the combustion chamber. Provides smooth control of the damper supplying air to the furnace, extends the burning process, maintains the heat phase, protects the furnace from overheating and cooling. It gives the current course of the combustion curve related to the current parameter in smoking. The controller has two temperature sensors - regulating the furnace and auxiliary to read the temperature at the exhaust gas outlet from the mass accumulation to the chimney. Possibility of cooperation with the furnace door sensor.
