CONFIGURATION 3
The configuration shown in the figure is set.
Connections on the control unit
Connections on the heating system (the following schematic is only illustrative)
The system includes: the hydro stove Boiler Probe (S1), the hydro stove Pump (P1), recirculation Pump (P2), Boiler/Puffer Probe (S2).
Set parameters on the hydro stove
T18 = 5°C, T19 = 53°C, T20 = 50°C, T21 = 80°C, T37 = 5°C, T38 = 60°C
Heating
• In Summer mode and working on Pellet, the Pump (P1) is activated above the thermostat T21. In all other cases the Pump (P1) is activated if
the temperature exceeds the value of the thermostat T19 if the difference of the temperatures read by the S1 and S2 probes is less than the
thermostat T37 or the water in the boiler has reached the desired temperature (thermostat Boiler T38).
• To prevent the water in the system from freezing, the Pump (P1) is activated when the water temperature drops below the thermostat T18 or, for
safety reasons, the Pump (P1) remains always active If the water temperature exceeds the value of the thermostat T21.
Domestic Water
•
The Pump (P2) must heat the water inside the domestic water boiler. It will activate only if the water temperature in the hydro stove exceeds the
value of the thermostat T20 and the difference between the S1 and S2 probe temperature readings is greater than the value of the thermostat T37.
• For safety reasons, if the water temperature in the hydro stove exceeds the value of the thermostat T21, the Pump (P2) is turned off.
