A fault can be cleared on the fault message status page by pressing key 3. BM-2 installed in the heating appliance.

− Check that the system is functioning correctly

15.2 Procedure for warnings

− Read warning message − Possible causes for the warning and remedies can be found in the "Faults" chapter − Determine and remedy the cause of the warning message − With warnings there is no need to acknowledge the fault − Check that the system is functioning correctly

15.3 Acknowledging faults for users

In case of a fault, the current fault is displayed along with the fault code, date and time.

The fault can be cleared by pressing the acknowledge key.

General informationNever remove, bypass or otherwise disable any safety or monitoring equipment. Only operate the heating appliance when it is in perfect technical condition. Any faults or damage which impact or might impact upon safety mustberemediedimmediatelybyaqualifiedcontractor.Onlyreplacefaultycomponentsandequipmentwithoriginal Wolf spare parts.Faults and warnings are shown in plain text on the display of the control accessories – AM display module or BM-2 programming unit – and correspond to the messages listed in the following tables.A warning/fault symbol on the display (symbol: triangle with exclamation mark) indicates an active warning or fault message. Fault history is listed at contractor level.

Warning messages do not need to be acknowledged and do not lead directly to the boiler being switched off. However, the causes of the warnings can lead to malfunctions of the boiler / system or to faults and should therefore be repaired by a qualified contractor.

The control unit automatically acknowledges faults such as faulty temperature sensors or other sensors if the part concerned has been replaced and plausible test values have been supplied.

18.2.1 Setting economy factor in economy mode

Setting range: 0...10Factory setting: 4

For a detailed description see the "Heating curve / Economy mode" chapter

The economy factor describes by how much the heating curve sets back the heating circuit or the mixer circuit when in economy mode. This factor has the same effect as the -4...+4 setting, but is only used in the time program during the setback phase or in setback mode.

Example of economy factor setting (setting procedure is always the same).

18.2.2 Setting winter/summer changeover

Setting range: 0 °C to 40 °CFactory setting: 20 °C

The winter/summer changeover function is only enabled if an outside sensor is connected.

The winter/summer changeover function optimises the times when the system operates in heating mode. If the average outside temperature is above the set winter/summer temperature, the heating system switches to standby mode.If the average outside temperature is below the set winter/summer temperature, the heating system switches to automatic timer mode.The period used to calculate the average outside temperature is set via the A04 system parameter.

18.2.3 Setting ECO ABS

Setting range: -10 °C to 40 °CFactory setting: 10 °C

The ECO ABS function is only enabled if an outside sensor is connected.

If the average outside temperature is above the ECO ABS temperature when in economy mode, the heating/mixer circuit switches to standby mode.If the average outside temperature is below the ECO ABS temperature, the control unit switches back to economy mode.You should only change the ECO ABS setting after consulting your contractor.

18.2.4 Setting day temperature (room temperature)

Setting range: 5 °C to 30 °CFactory setting: 20 °C

Day temperature is only enabled for this heating/mixer circuit when the room influenceisenabledandtheBM-2isinstalledinthewallmountingbase.Use the day temperature to set the required room temperature in heating mode, party function mode and the heating phases during automatic mode. In setback mode, economy mode and during the setback phase in automatic mode, the room temperature is only set to the day temperature less the economy factor (see point 18.3.1).

18.2.5 Settingroominfluence

Setting range: ON / OFFFactory setting: OFF

Roominfluence is only active if the BM-2 programming unit is installed as a remote control.Room influencecanbeused tocompensate forfluctuations in room temperaturedue to external sources of heat and cold (e.g. insolation, woodburning stoves or open windows).

The deviation fromthesetvalueismultipliedbytheheatingcurveandtheroominfluencefactor,andtheflowtemperatureisincreasedordecreasedbythisvalue.

Smallroominfluencefactor = littleeffectonflowtemperatureLargeroominfluencefactor = strongeffectonflowtemperature

22.3.2 Setting average outside sensor (A04)

Factory setting: 3 hSetting range: 0 to 24 h

For some automatic functions (e.g. summer/winter changeover, ECO ABS), the BM-2 programming unit calculates an average outside temperature using the current outside temperature over several hours. Set the calculation time period using the "Outside sensor avg." parameter.If the time is set to 0 hours, the BM-2 programming unit does not calculate an average value; instead the average value is always the same as the current outside temperature. The outside temperature display at control level 1 will not be adjusted.

22.3.3 Setting the pasteurisation function (A07)

Factory setting: OFFSetting range: OFF, Mo...Su, daily

Danger!Risk of scalding from hot water!

f When the pasteurisation function is enabled, the DHW temperature is set to 65 °C, as long as the actual DHW temperature has been maintained continuously for onehourat≥60°C.Oncethepasteurisationfunctionhasbeenenabled,itcanbe disabled either by removing the current from the BM-2 programming unit, or by modifying the A07 parameter. The DHW circulation pump is also enabled while the pasteurisationfunctionison.IftheactualDHWtemperatureof≥65°Cisachievedvia an external source (e.g. solar energy), and maintained for one hour, the pasteurisation function will be blocked for that day. Please inform the user about the timing of the pasteurisation function.

Use the A07 parameter to select the day on which the pasteurisation function should begin, e.g. A07 = daily – pasteurisation func. starts every day

Use the A23 parameter to preset the start time for pasteurisation for the relevant day.

46 3064203_201508


22.3.4 Setting the frost protection limit (A09)

Factory setting: 2 °CSetting range: -20 to +10 °C

CautionMaterial damage from frostFrost can cause the heating system to freeze up and cause material damage to the system and the premises.

f Please observe the frost protection settings of the heating appliance. f Ensure that the system is adequately protected against frost. f Please inform the user about the frost protection measures taken. f Ensure that there is a constant power supply to the heating appliance.

The heating circuit pump will run continuously if the outside temperature falls below the selected value.The burner starts and heats up the boiler to the minimum boiler water temperature if the boiler water temperature falls below the permanently set value of +5 °C.

22.3.5 Enabling parallel operation (A10)

Factory setting: OFFSetting range: OFF / ON

CautionMaterialdamageduetohighflowtemperaturesParallelDHWoperationcanmaketheflowtemperatureoftheheatingcircuithigherthan the set value, which can lead to material damage. Set DHW priority control for underfloorheatingwithnoseparatemixer.

DHW priority controlDHW heating takes priority over heating mode. As long as water is being heated, heating mode does not run. The cylinder charging pump starts if the boiler water temperature is 5 °C hotter than the cylinder water temperature. As soon as the set DHW temperature is reached, the burner shuts down and the heating circuit pump starts. The cylinder pump runs on for the period set under parameter HG19 (SLP run-on time).

Parallel DHW operationHeating and DHW heating operate simultaneously. With simultaneous operation, the heating circuit can be heated to higher temperatures than needed or set.

0 = DHW priority control1 = Parallel DHW operation

For wall-mounted boilers with a priority changeover valve for DHW heating, this parameter has no function.

22.3.6 Room temperature shutdown (A11)

Factory setting: ONSetting range: ON / OFF

When room temperature shutdown is enabled, the corresponding heating/mixer circuit shuts down if the day temperature exceeds + 0.5 K. The heating/mixer circuit pump does not restart until the room temperature falls below the day temperature. Roominfluencecanbeusedtocompensateforfluctuationsinroomtemperaturedue to external sources of heat and cold (e.g. insolation, woodburning stoves or open windows).

Example 1:Room temperature shutdown prevents the area from being overheated if room influenceisenabledandthelivingareaisheatedonlybytheheatingsystem.

Example 2:Room temperature shutdown can occur if a room where the programming unit is installed (e.g. living room) is heated by a second heat source (e.g. woodburning stove)androominfluenceisenabled.Thiswouldresultinotherroomscoolingdown.Remedy: Switch OFF room temperature shutdown (OFF).

22.3.7 Setting setback stop (A12)

Factory setting: -16 °CSetting range: -30 to 0 °C

The BM-2 programming unit switches from setback mode to heating mode if the average outside temperature falls below the set value.

22.3.8 Setting the minimum DHW temperature (A13)

Factory setting: 45 °CSetting range: 15 to 65 °C

The A13 minimum DHW temperature parameter is only enabled when a solar extension module is connected.

The solar thermal system can be used to heat up the DHW cylinder above the set DHW temperature, and solar heating is successful. When solar heating is successful, the heating appliance will not heat up the DHW cylinder unless it falls below the minimum DHW temperature, or the set DHW temperature is not reached by 14:00 h the next day. If the minimum DHW temperature is not achieved, the DHW cylinder will be heated by the heating appliance.
