➢
3 = Boiler connected to a heating system and DHW storage water heater.
Plant Type “
3
” involves connecting the boiler to a heating system managed by one or more room
thermostats connected to the terminal located inside
the appliance’s technical compartment. DHW will be produced by means of a hot water cylinder mounted outside the appliance an
d controlled by a
temperature probe connected to it.
The motor-driven three-way valve
–
controlled by the pellet-fired appliance
–
will manage heating of the system or of the hot water cylinder, giving
priority to the latter.
Through “Menu 01 –
PLANT MODE = DHW” only the hot water cylinder will be managed during summer and the heati
ng system will be left off.
➢
4 = Boiler connected to a centralised puffer controlled by a H2O sensor connected to it.
Plant Type “
4
” involves connecting the boiler to a ce
ntralised puffer managed by a temperature sensor connected to the terminal located inside the
appliance’s technical compartment. The appliance will operate only at the set temperature of the centralised puffer (“SET PUFFER” which can be set
using buttons 1 and 2). This system configuration does not involve any connection of room thermostats or three-way valves to the appliance. These
devices will thus have to be managed separately as required.
