Residential Heating and Hot Water System
Boiler Controller
1. It is the individualized heating controller adapt to design demands, whether in the old-fashioned residential or in low energy housing, it can meet the personalized needs of modern design, and control two independent heating circuits in case of adopting the independent heating system or an additional floor heating system.
2. Heating operation is easy and simple: the heating operation with pressing followed by rotating can become so simple: To hold down the function key, use the knob to adjust the desired value, and then release the button, the operation is end. The system will automatically receive the new overall values. All the keys would be with the special markings for convenience of facilitating in finding the right features, because no one wants to waste time in the heating room.
3. The demands of safe and easy control, low-emission, low temperature operation, heating economy require reliable regulation, which is the prerequisite for extending the boiler service life. Controller CFB 240 can reduce the number of starts of burner, thus reducing emissions and saving operating costs.
4. Indoor temperature control: the application of the remote control BFU, can easily regulate the room temperature.
5. The control system seek the best way according to the instructions, controller CFB 240 can continuously check the most economical way to ensure that the desired room temperature and water temperature. In which, an advanced technology plays the important role: Dynamic conversion differential. This feature may extend burner running time and greatly reduce the number of conversions. For example, in energy-efficient housing, the power of drinking water heating boiler power is more than that of room heating. Therefore, the controller of CFB 240 can make the burner to start the conversion difference at any time to adapt to the actual heating. The advantage is to start to radically reduce emissions and combustion residues (such as carbon black).
