Cleaning the boiler - By pressing the button ’’START’’ (1) fan will begin work (2), an burner grate (3)
will move into the open position (100%) (4), (button ’’START’’ will become a button’’STOP’’).
This option enables you to during cleaning of combustion chamber, boiler ash does not come out of
the boiler, and since the burner grate is open ash falls into the ash box. After cleaning, it is necessary
to press the ''STOP'' to shut off the fan and burner grate move back to the closed position (0%) (4)
(same thing will happen if you press the button ''BACK'' (5)) . After cleaning, it is necessary to empty
the ashtray.

1.2. FILLING AT START
Filling at start - by pressing ''START'' (1) pellet feeding screw starts to operate (2) (works 25 min),
and the burner grate (3) moves to the open position (100%) (4) to make pellets fell down in ashtray
After this process is complete pellet feeding screw stops working, the burner grate is returned to the
closed position (0%) (4). After completion of the initial filling of pellets ashtrays need to put in pellet
tank. For the duration of this process, the display shows the countdown process duration (5). Before
starting this process, it is necessary to fill the pellet tank. The process may be interrupted by
pressing button ''STOP'' or ''BACK'' (6).
1.3. SYSTEM AIRVENT
System airvent - entering the above menu, the motor device of 4-way mixing valve opens the valve
to 50%(1). By pressing START'' next to a particular pump symbol, the pump starts to work (2, 3, 4)
(button ’’START’’ become button ’’STOP’’). By pressing the button ''STOP'' the pump stops
working. In this option is not possible to work 2 or 3 pumps at the same time.

Description of work:
The regulation reads on the upper sensor accumulation tank temperature, minimum accumulation
tank temperature and accumulation tank difference. At the bottom sensor, regulation reads the
accumulation tank shutdown difference that can be set in the installation menu (under PIN). When
the boiler is switched on, it works until the temperature on the lower sensor (T accumulation tank - T
accumulation tank shutdown difference) is reached. The boiler will turn ON again when
accumulation tank upper temperature (upper sensor) reach the (T accumulation tank - T
accumulation tank difference).
