5 Energy saving tips 5 Energy saving tips Installation of a weather compensator Weather compensators regulate the heating flow temperature with reference to the outside temperature. No more heat is generated than is currently required. The designated heating flow temperature for the corresponding outside temperature must be set on the weather compensator. This setting must not be greater than that required by the design of the heating system.
Energy saving tips 5 the extent that is necessary for use. Any further heating results in unnecessary power consumption and hot water temperatures of more than 60 °C also lead to increased lime scale reduction. Switching on comfort mode (only VUW): Comfort mode immediately supplies you with hot water at the required temperature, without you having to wait for the water to heat up. For this, the hot water heat exchanger is kept at a preselected temperature level.
6 Troubleshooting 6 Troubleshooting a Display Danger! Danger of injury and material damage due to incorrect maintenance and repairs! If maintenance is not carried out, or carried out incorrectly, this may adversely affect the operating reliability of your boiler. > Never attempt to perform maintenance or repairs on your boiler by yourself. > Always employ an approved heating engineer.
Troubleshooting 6 6.1 Reading fault codes If a fault develops in the boiler, the display shows a fault code starting with "F...". A plain text display explains the displayed fault code. Example for F.10: "Short circuit heating feed sensor". Fault codes have priority over all other displays. If a fault occurs, then the display no longer shows the current heating flow temperature.
Troubleshooting 6 6.3 Rectifying a water shortage b Caution! Tap water that is extremely calciferous or corrosive or contaminated by chemicals can cause material damage! Unsuitable tap water damages the seals and diaphragms, blocks components in the boiler and heating system through which the water flows and causes noise. > Only fill the heating system with suitable tap water. > In case of doubt, consult your approved heating engineer. 6.

Glossary Glossary Air/exhaust gas pipework The air/exhaust gas pipework consists of all components that route combustion air to the boiler or exhaust gas from the boiler. Burner The burner on a condensing boiler is the component in which the gas/air mix is control-burnt. Calorific value Unlike the heating value, the calorific value of a fuel describes the total useable heat during combustion, based on the quantity of fuel used, including the condensation heat in the steam.
Glossary Room thermostat A room thermostat continuously measures the room temperature and compares it with the room temperature you have set (target room temperature). This allows the heating system to maintain a constant set temperature in your room. In addition, you can enter individual heating times. The target room temperature and the heating times set by you control the operation of your boiler, the power of which is adapted automatically to the respective heat demand.
