The heart of a modern Calimax Pellet Stove is the control mechanism. An integrated room sensor measures the temperature in the room; if the room temperature is lower than the pre-set temperature, the stove ignites automatically.

The pellets are fed into an optimally controlled combustion chamber. An auger feeds the pellets from the hopper into the burn pot. The control mechanism starts the ceramic ignition system. Once the stove reaches a temperature of about 200°C, the pellets ignite. The start phase is complete after about 15 minutes, and the control program switches to the normal heating control mode.

Calimax pellet stoves are able to operate continuously for up to 70 hours – depending upon heat output. The heat setting depends on the temperature difference between the desired temperature and the actual temperature.

The control mechanism also regulates the ratio of fuel to air. Since the fuel quality is defined in the DIN 51731 and Ö-NORM M 7135 standards (size, moisture content, BTU output ...) the on/off operation of the drive motor regulates the necessary amount of fuel. Similarly, the speed-regulated exhaust fan can precisely regulate the combustion air.
