Boiler for wood and pellets ATTACK DPX COMBI PELLET

Boiler regulation

Regulation PROFI

If you need your new boiler for buildings in which you will heat regularly and you need to control more devices, we recommend you a boiler with PROFI control. (You can find it in DPX, SLX, DPX Combi Pellet and SLX Combi Pellet boilers.) This reliable control achieves better efficiency than Standard control because it uses a more accurate PID controller. Thanks to this a more precise and smooth control of the fan speed is achieved and thus it is possible to better control the flue gas temperature which affects the final efficiency of the boiler.

In addition to PID regulation, Fuzzy Logic technology is also involved in better combustion performance. It takes care of burning monitoring sensors and adjusts its process in real time to be as efficient as possible.

You don’t have to worry about a complex system with the PROFI version. The control unit can control the heating circuit pump and the accumulation tank or DHW accumulation tank. It also handles the accumulation tank and prevents from its discharging. The regulation will even take care of shutting down the boiler for you if it runs out of fuel.

PROFI regulation is very simple and intuitive to operate. The display shows you all the necessary operating information (boiler temperature, flue gas temperature, accumulation tank temperature) and the current operation of the individual elements (fan operation, DHW / accumulation tank charging pump, circulation pump operation). If you decide for a boiler with this regulation, you will be rewarded with quality combustion and reliable efficiency.
