High Water Pressure Relief (3 Bar)
Protects the radiator heating circuit and device against possible increase in pressure.
Low Water Pressure Relief (0,5 Bar)
Prevents the device operation in low water pressure.
Ensures water circulation in the device to prevent heat build-up.
Compensates for the expansion of the hot water in the heating circuit.
The filtration system that provides electromagnetic compatibility.
Checks for the presence of flame in burner.
Pump Anti-Blockage System
Prevents blocking of the pump by running it in every 24 hours as long as there is electrical connection.
3 Way Valve Anti-Blockage System
Prevents blocking by running the 3 way valve in every 24 hours as long as there is electrical connection.
In the case of electricity and gas supply is available, Anti-Freezing System activates the device automatically when mains water temperature is below 5°C.
Ensures automatic expulsion of the air in the heating installation.
Provides protection against overpressure in the heating installation.
Overheating Safety Thermostat (90° C)
Stops the device operation if heating water temperature exceeds safety level.
Turns off and secures the device when sufficient air flow is not available inside the device.
Limits the temperature of the water exiting the heat exchanger to 105° C.
