1. A contaminated burner or poorly adjusted boiler can reduce the heating system efficiency Regular heating system maintenance through your local contractor quickly pays for itself Heating at the lowest energy level Operate your heating system where possible with a return temperature of less than 45 C to achieve the highest possible utilisation of condensing technology A heating system control unit also regulates your heating costs A heating system in standby mode saves energy A modern weather compensated or room temperature dependent heating system control unit ensures with automatic night setback and thermostatic valves that the system only operates when heat is required saving money for the rest of the time Equip your heating system with a weather compensated heating controller from the Wolf range of accessories Your heating contractor will be happy to advise you about optimum adjustments In conjunction with the Wolf control unit accessory use the night setback function to match the energy level to the actual demand period Use the optional summer mode adjustment Never overheat your home Adjust the room temperature as accurately as possible This leaves occupants comfortable and energy is not wasted on providing heating output that nobody needs Differentiate between the optimum temperature for different rooms such as living rooms and bedrooms A room temperature which is one degree higher than necessary r2. ring Explanation Flashing green Standby power supply ON burner OFF e g summer mode Constant green light Winter mode Pump running burner OFF Flashing yellow Emissions test mode Constant yellow light Burner operating flame ON Flashing red new Summer mode heating OFF Mdi Winter mode position 2 to 8 7 Emissions test mode illuminated ring flashing yellow DHW temperature selector boiler 1 15 C 9 65 C m Heating water temperature selector 2 20 C 8 75 C Note The BM programming module can also be integrated into the boiler control unit That means that all adjustments are made at the boiler control unit For installation and operation see installation instructions ij j 5 G and BM programming module operating rn ar SF instructions a6 Je 6 3062548_0409 WOIF Heating mode 3062548 _ 0409 Information for energy efficient operation Saving energy with modern heating technology oil condensing technology saves your cash Modern condensing technology utilises that energy for heating which in conventional heating systems is expelled unused to the atmosphere with the flue gas Use as little electrical energy as possible Operate your system with multi stage heating pumps at the lowest possible level Modulating pumps generally do not require adjustments since they are automatically matched to the prevailing demand Regular heating system maintenance pays for itself
