Why is my Vaillant recoVAIR VAR 360/4 product not operating?
If your Vaillant Boiler isn't operating, it could be due to an interruption in the mains voltage or a power cut. The suggested solution is to wait until the mains voltage has been re-established. The product should automatically switch on, retaining all previous settings.
Why does my Vaillant Boiler have an increased noise level?
An increased noise level in your Vaillant Boiler could stem from a few issues. One potential cause is missing or incorrect silencers in the supply-air or exhaust-air pipes; in this case, install silencers according to the system planning. Another possibility is that system components like the heat exchanger or fan are defective, so replace any defective components. Alternatively, dirty system components such as the heat exchanger or fan could be the cause, in which case you should clean them.
Why is the supply air from my Vaillant recoVAIR VAR 360/4 too cold?
If the supply air is too cold, it could be due to several reasons. First, the supply-air and exhaust-air flows might not be balanced, so you should adjust the product. Also, check the flap position, and replace the bypass motor if it is defective. Another potential cause is dirty system components, such as the heat exchanger or fan, so clean them. Finally, frost protection might be active; in this case, check whether S.815 is displayed in the Live Monitor and wait until the outside temperature increases above ?3°C. The product should automatically switch on no later than 60 minutes after the temperature increases.
Why is water dripping out of my Vaillant Boiler?
If water is dripping out of your Vaillant Boiler, it could be because the exhaust-air lines or supply-air lines aren't insulated to ensure that they are vapour-diffusion-tight. To fix this, insulate both the exhaust-air and supply-air lines, making sure the insulation is vapour-diffusion-tight.
How to fix bypass summer mode not working on Vaillant Boiler?
If the bypass summer mode isn't working, there are several things you can check. First, make sure the bypass function is active and that you've set the planned operating days for summer mode. Inspect the plug connection to the bypass motor and check the temperature sensor. If the bypass motor is defective, replace it. Also, verify the flap position and the positioning of the temperature sensor.
What to do if the supply air target volume flow is not achieved in my Vaillant recoVAIR VAR 360/4 Boiler?
If the supply air target volume flow isn't being achieved, the cause might be an incorrect fan specification. To resolve this, check the fan connection, the fan size (up to 260 m/h or 360 m/h), and the fan power.
Why is the planned air volume flow not available after installation of my Vaillant Boiler?
If the planned air volume flow isn't available after installation, the issue might be that the installation isn't vapour-diffusion-tight. Check that all of the connections are leak-tight.
Why are there bad and/or unpleasant odors present with my Vaillant Boiler?
If you're experiencing bad or unpleasant odors, it could be because the openings for the supply-air and exhaust-air lines are too close to each other. To resolve this, increase the distances between these openings.
Why are there noises in the condensate drain pipework of my Vaillant Boiler?
If you're hearing noises in the condensate drain pipework, it's possible that the condensate siphon is connected incorrectly. Ensure that the condensate siphon is connected correctly.
How to stop noise transmission between the rooms from my Vaillant recoVAIR VAR 360/4?
If you're experiencing noise transmission between rooms, it could be due to the absence of a T supersonic damper. To address this, install T supersonic dampers and then adjust the product.
