PLUMBING CONFIGURATION

It is possible to integrate the hydro stove to one of the following hydraulic system configurations considered most suitable. To set the configuration, an
authorized technician must be contacted.
CONFIGURATION 0
The configuration show in the figure is set. This is the standard setting.
If the domestic hot water kit is installed, it is not necessary to change the setting on the hydro stove.

The system includes: the hydro stove Boiler Probe (S1), the hydro stove Pump (P1), Electrovalve of the kit (P2), Flow Switch of the kit (FL).
Set parameters on the hydro stove
T18 = 5°C, T19 = 53°C, T20 = 50°C, T21 = 80°C
Heating
•
The Pump (P1) activates above the thermostat T20.
•
In Summer mode and working on Pellet, the Pump (P1) is activated when the water temperature exceeds the value of the thermostat T21.
• To prevent the water in the system from freezing, the Pump (P1) is activated when the water temperature drops below the thermostat T18.
• If the water temperature exceeds the value of the thermostat T21, for safety reasons the Pump (P1) remains always active.
Recirculation
•
When there is a demand for domestic hot water and the water temperature in the hydro stove exceeds the value of the thermostat T19 or the
thermostat T20, the Valve (P2) is active.
•
If the water temperature exceeds the value of the thermostat T21, the Valve (P2) switches towards the heating system.
