Description of operation
Ravelli pellet boiler HR EVO Smart are appliances for domestic heating powered by wood pellets with automatic loading.
The heat generated by the combustion of the pellets is transferred to the water in the heating system of the house or to the domestic
hot water.
With these boilers it is possible to manage different types of hydraulic system, as described in this manual.
The boiler is controlled by an electronic control unit that manages the start-up, operation and shutdown phases and also includes
many other functions for control, programming and safety.
The user can set the system water temperature and the boiler will manage the power to ensure maximum comfort. Among the func-
tions of the electronic control unit there is also that of being able to program the boiler's start-up and shutdown by setting the weekly
chronothermostat.
Ravelli's patented cleaning system minimises maintenance by the user. There is no longer any need to clean the brazier before each
lighting and all cleaning operations are reduced to a minimum.
