Boiler regulation

Characteristics of regulation PROFI

Suitable for everyday heating
PID regulation – more accurate and smooth fan speed control
Fuzzy Logic control sensors
Controls 2 pumps (heating circuit pump + accumulation tank or DHW charging pump)
For storage tank solutions – built-in logic for tank charging and discharge protection
Simple operation and display showing current operating information (boiler temperature, flue gas temperature, accumulation tank temperature)
Monitoring of parameters (fan operation, DHW charging / storage tank operation, circulation pump operation)
Thermostat control of the circulation pump
Automatic shutdown of the boiler after burning fuel
Manual setting of primary and secondary air

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 boiler. 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.
PROFI control 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.

Regulation LAMBDA Touch

Lambda Touch controller is the most modern control electronics. The control is based on the LAMBDA controller. A Lambda probe is used to evaluate combustion parameters, regulate the supply of primary and secondary air (automatically), optimize combustion, and thus achieve overall higher heating efficiency.
A static public IP address is required for the application to function properly. During development of control we also thought about the software in regulation as recent as possible. Therefore, there is a USB connector in control through which you simply update the software to the latest version.
The Lambda Touch control can enable the boiler to be put into operation after heat consumption from the accumulation tank, charging the accumulation tank, as well as various expansion modules such as: 2 mixing circuits, DHW storage tank, solar panels. With Lambda Touch control you get a modern way to control your boiler with a clear display and advanced control options.
