Safety instructions Safety instructions (cont.) If you smell flue gas Danger The simultaneous operation of the boiler and appliances that extract air to the outside can result in life threatening poisoning due to reverse flow of the flue gas. Fit an interlock circuit or take suitable steps to ensure a sufficient supply of combustion air. Danger Flue gas can lead to life-threatening poisoning. ■ Shut down the heating system. ■ Ventilate the installation site. ■ Close all doors in the living space.
Safety instructions Safety instructions (cont.) Auxiliary components, spare and wearing parts Please note Spare and wearing parts that have not been tested together with the system can compromise its function. Installing non-authorised components and making non-approved modifications or conversions can compromise safety and may invalidate our warranty.

Preparing for installation Intended use Intended usage presupposes that a fixed installation in conjunction with permissible, system-specific components has been carried out. Any usage beyond this must be approved by the manufacturer for the individual case. Incorrect usage or operation of the appliance (e.g. the appliance being opened by the system user) is prohibited and results in an exclusion of liability.

Function description Constant temperature control unit °C 48 s A Heating mode The selected set boiler water temperature will be maintained when a demand is being raised by the room thermostat and the heating program is set to DHW and central heating "G". The boiler water temperature will be maintained at the default frost protection temperature when there is no demand. The electronic temperature limiter inside the burner control unit limits the boiler water temperature.
Function description Constant temperature control unit (cont.) In the delivered condition, the set boiler water temperature is 20 K above the set DHW temperature (adjustable via coding address "60" in group "DHW" (weathercompensated control units) or group 3 (constant temperature control units). The burner will be switched off and the circulation pump run-on time will begin, if the actual cylinder temperature exceeds the set cylinder temperature by 2.5 K.
Function description Weather-compensated control unit (cont.) DHW heating with gas condensing combi boiler If the flow switch detects that DHW is being drawn off (> 3 l/min), the burner, circulation pump and 3-way valve are started or changed over.
