4.4 Work stage

After the 'STARTUP' stage, the boiler goes to the 'WORK' mode which is the normal operation mode.
The user can adjust the heating power from the max. value of 5 to a min. of 1 with the buttons 'P5' and 'P6'.
DHW circuit function activation ON is displayed by the segment/LED [A].
Make sure to check the pellet level in the hopper so that the flame does not go out due to lack of pellets.
Make sure the unit is off when loading pellets.
The pellet hopper lid must always remain closed; it must only be opened when loading fuel.
The bags of pellets must be kept at least 1.5 m from the boiler.
