Viessmann Atola-RN Operating Instructions

To reset your Viessmann Atola-RN Boiler, locate the reset button on the control panel. Press and hold the button for a few seconds until the system restarts. If the issue persists, consult the user manual or contact a professional technician.
If your boiler is leaking water, first turn off the water supply and power to the boiler. Check for any visible cracks or loose connections. Tighten any loose valves and replace any damaged parts. If the leak continues, contact a certified technician for further assistance.
It is recommended to service your Viessmann Atola-RN Boiler annually to ensure optimal performance and safety. Regular maintenance can help prevent breakdowns and extend the lifespan of the boiler.
Unusual noises from your boiler may indicate air in the system, low water pressure, or a faulty pump. Bleed the radiators to remove air, check the pressure gauge, and ensure it is between 1 and 1.5 bar. If the problem persists, contact a professional technician.
Check the thermostat settings and ensure the boiler is receiving power. Inspect the pilot light or electronic ignition to ensure it is functioning. If these appear normal, a faulty component may be the cause, and you should contact a qualified technician for repairs.
To increase the water pressure, locate the filling loop and slowly open the valves to allow water into the system. Monitor the pressure gauge and close the valves once the pressure reaches between 1 and 1.5 bar. Be cautious not to overfill the system.
If the pilot light keeps going out, it may be due to a faulty thermocouple, gas valve, or a draft affecting the flame. Ensure there are no drafts and check for any visible obstructions. If the issue persists, consult a professional technician for further evaluation.
Yes, you can use a compatible smart thermostat with your Viessmann Atola-RN Boiler. Ensure the smart thermostat is compatible with your boiler model and follow the installation instructions provided by the thermostat manufacturer.
To bleed the radiators, turn off the heating system and allow it to cool. Use a radiator key to open the bleed valve at the top of each radiator, starting from the lowest floor. Allow trapped air to escape until water starts to flow, then close the valve. Repeat the process for each radiator.
It is recommended to use an inhibitor treatment to prevent corrosion and lime scale build-up in the system. Ensure that any water treatment used is compatible with your boiler and follow the manufacturer's guidelines for dosage and application.
