PELLET-BURNING BOILER ECOMPACT 150-190-250-290
EN - Rev 1.1
PLUMBING LAYOUT “2” – Boiler with built-in instant DHW, connected to a heating system with an additional DHW
generator.
Plumbing layout 2 involves the connection of the boiler with built-in instant DHW (prepared models only) to a heating
system managed by one or more room thermostats. These are connected to the terminal provided inside the left
technical compartment on the appliance. DHW generation is achieved via a mini storage tank built-into the appliance. It
is recommended to fit an alternative generator in order to guarantee constant DHW in this type of system. Control of this
combination is ensured by a three-way motorised valve connected to the pellet boiler. This allows the DHW generated by
the pellet boiler to be used only when it is operational and at a suitable temperature.
PLUMBING LAYOUT “3” – Boiler connected to a heating system and DHW storage boiler.
Plumbing layout 3 involves the connection of the boiler to a heating system managed by one or more room thermostats.
These are connected to the terminal provided inside the left technical compartment on the appliance. Any DHW
generation is achieved by a storage boiler fitted externally to the boiler. This is controlled by a temperature sensor
connected to the appliance.
