CONFIGURATION 1
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), Flow Switch (FL).
Set parameters on the hydro stove
T18 = 5°C, T19 = 53°C, T20 = 50°C, T21 = 80°C
Heating
• The Pump (P1) is activated above the pump activating thermostat T19.
• If there is a demand for domestic hot water the Pump (P1) is blocked.
• 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 Pump (P2) is active.
• If the water temperature exceeds the value of the thermostat T21, for safety reasons the Pump (P2) is turned off.
