Central heating boilers of vitoPELLETS type are low-temperature ecological central heating boilers designed for efficient and fully- automated combustion of biomass in pellet form. In the central heating boiler a chute burner is used, along with a highly technologically advanced controller of RK-2006 LP type.
The main advantage of DRAGON central heating boilers is comfortable and very easy operation, practically reduced to periodical fuel filling in the intake hopper (every 3 - 6 days depending on weather conditions and the level of building is insulation).
DRAGON central heating boilers are constructed in order to enable attachment of an external fuel feeding system providing fuel from main storage room. Regular maintenance includes scheduled emptying of the ash pan.
The universality of these central heating boilers consists in the possibility of a fuel tank (hopper) installation both on the left and the right side.
The innovative auto- inflammation system and automatic burner cleaning system enable burning of lower quality (dirty), low-priced fuels. Therefore, the vitoPELLETS central heating boilers have been recognized as the most economic and most environmentally- friendly central heating boilers in their class.
The RK-2006LP controller is a device used to control the temperature of the pellet-filled boilers.
The level of the temperature of the boiler is kept at the level set by the user by controlling the blowing fan and the feeding screw or the dosing feeder co-operating with the built-in internal feeder (stoker). The controller makes it possible to control the central heating circulation pump and the domestic hot water pump. The controller also has a function of automatic fuel ignition.
The LCD text display allows a simple, intuitive operation. A wide range of functions allowing programming the parameters of the controller allow a precise adjustment of the parameters of the boiler operation in accordance with the heating system.
The controller is equipped with STB - independent electronic protection of the boiler against overheating.
In order to guarantee a more precise control of the temperature of the heated rooms, the controller has been equipped with an input making it possible to connect any room thermostat with an output switch.
The casing of the controller is adjusted to the standard dimension of 144 x 96 mm.
The controller is adequately equipped with a secured semiconductor temperature sensors.
