5th class pellet boiler

Pellet boiler ONE BASIC is a modern compact boiler with small dimensions. Weather automatics with Lambda probe and HT-Logic III autoregulation for smooth and user-friendly operation. It is equipped with a burner with automatic cleaning and a return protection pump.

The boiler structure is based on a vertical flame tube heat exchanger with a mechanical exchanger cleaning system. Burning is performed by a self-cleaning, automatic drop-in burner with an openable floor, equipped with an igniter, a photoelement and a thermocouple. The boiler is equipped with an exhaust fan which aerates the combustion process and improves the flue draught.

The boiler and heating system is controlled by HT – Tronik 900 weather controller which controls the operation of 4 pumps and a mixing valve actuator. The automatics can be expanded by connecting additional modules. The controller is compatible with a remote control panel, 2 room thermostats and an internet module. It is equipped with HT-Logic III autocontrol which controls the operation of the burner, selects the operating parameters and modulates power depending on the boiler temperature.

Operates in iPell R combustion optimisation standard with HT-tronic Lambda module. The optimisation system with a probe guarantees the highest combustion quality.

The boiler is protected by a return protection pump with temperature sensor. It is suitable for fitting in a closed system in accordance with applicable legislation.
