To adjust the heating temperature, access the main menu on the boiler’s control panel, navigate to the 'Heating' settings, and adjust the desired temperature using the up and down arrows.
Refer to the user manual for specific fault codes. Often, resetting the boiler can resolve minor issues. If the fault persists, contact a qualified technician for inspection.
Ensure regular maintenance, insulate pipes, install a smart thermostat, and set the boiler to operate on lower temperatures when full heat is not required.
Annual maintenance by a certified technician is recommended. This includes checking the heat exchanger, burner, and ensuring all components are functioning properly.
Turn off the heating system and allow radiators to cool. Use a radiator key to slowly open the bleed valve until water starts to escape, then close the valve.
Check the thermostat settings to ensure they are correct, inspect the power supply, and verify that the water pressure is within the recommended range.
Locate the reset button on the control panel, press and hold it for a few seconds until the display indicates a reset. Always consult the manual for specific instructions.
Some noise is normal due to the boiler’s operation. However, loud or unusual noises may indicate a problem such as air in the system or a component issue and should be investigated.
Check the pressure gauge on the boiler; it should be between 1.0 and 1.5 bar. To adjust, use the filling loop to add water to the system if the pressure is low.
Signs that your boiler needs servicing include unusual noises, fluctuating pressure levels, inconsistent heating, and error codes appearing on the display.
