Appendix16 Installation and maintenance instructions auroSTOR 0020221298_04AppendixA Detecting and eliminating faultsFault Possible cause RemedyNo flow rate at the valve 1. Water supply valve closed2. Main filter blocked3. Pressure reducer not installed correctly1. Check and open the valve.2. Close the water supply valve, clean the filterand the water pressure reducer.3. Check whether the pressure reducer has beeninstalled correctly.Low flow rate and pres-sure at a valve1. Filter in cold water supply clogged 1. Close the cold water supply, clean the filter forthe water pressure reducer.Water from the valve iscold1. The cylinder was not set or is not operating.2. The heat generator does not work.3. The thermal cut-out was triggered.4. The 2-port motorised valve is not working5. The immersion heater does not work.1. Check the thermostat or the room thermostatand, if required, set this.2. Check the heat generator; a fault code ispresent.3. Check and initialise the cylinder.4. Check the valve's connections.5. Set the thermostat or the room thermostat.Domestic hot watertemperature too high1. Use a thermometer to check the temperature; itmust be between 60 and 65 °C.2. Check the cabling.3. Thermostat set too high4. Defective thermostat1. Install a mixer tap.2. Repair the cable.3. Reduce the temperature of the thermostat to55 °C.4. Replace the thermostat.Irregular domestic hotwater output at the valve1. Defective expansion vessel2. Thermal control1. Set the expansion vessel.2. Interrupt the power supply of the product andheat generator, check the thermal cut-outs andreplace these if you find any defects.B Inspection and maintenance work – OverviewN° Work Maintenance-re-lated interval1 Check the connections for tightness. Annually2 Check the temperature and pressure expansion relief valve. Annually3 Check the expansion relief valve. Annually4 Check the pressure in the expansion vessel. Annually5 Check the domestic hot water output at the valve (if required, clean the filters). Annually6 Check the target domestic hot water temperature. Annually7 Check whether the thermostatic mixing valve is working. Annually8 Fill out the cylinder's benchmark checklist.
