5.5.1 Indicative hydraulic diagram heating only
Caution
: to prevent the heating system from having to be regularly cleaned it is best to
install a magnetic
sludge remover
, this filter aids routine maintenance, increases boiler life span, aid removal of impurities and
increased global efficiency of the system.
The magnetic sludge remover
filters the heating system
removing sludge, ferrous or sandy residues which
circulate in the pipes, if not removed they create surfaces which do not permit heat transmission, consequent
pellet consumption and possible boiler malfunction
.
5.6 External thermostat installation
Stove operation can be adjusted to any external room thermostat connected to the circuit board (see electrical
diagram). The thermostat connection is made using a 2x0.5 mm2 cable.
This operation should be performed by qualified personnel.
If you choose to use an external thermostat, set the room temperature value on the stove display to the
minimum (7°C).
At this point, the stove will be controlled by an external thermostat.
During the work phase, the external thermostat is closed. The stove works at the set power level. A virtual
LED will activate on the upper left of the display. If the thermostat opens, the stove goes to minimum power
level and the display shows the message "modulating". This modulation stops only if the thermostat goes
back to being closed. In this case, the stove will return to the power set by the user, the display will show the
message "modulating" and an indication of the set power level will return.
