Page 3: Safety Instructions / Standards
Safety instructions / Standards Safety instructions The following symbols are used in conjunction with these important instructions concerning personal safety as well as operational reliability. "Safety instructions" are instructions with which you must comply exactly, to prevent injury and material losses. Danger through 'live' electrical components. NB Switch OFF the ON / OFF switch before removing the casing. Never touch electrical components or contacts when the ON / OFF switch is in the ON position. This brings a risk of electrocution that may cause injury or death. The main supply terminals are 'live' even when the ON / OFF switch is in the OFF position. This indicates technical instructions that you must observe to prevent material losses and boiler malfunctions. -
Page 4: Standards / Regulations
- Never remove, bypass or disable safety and monitoring equipment. - Only operate the system in perfect technical condition. Immediately remove / remedy any faults and damage that may impact on safety. - Always ensure that cold water is mixed in with hot water, when the DHW temperature is set above 60 °C (risk of scalding). Maintenance / Repair - Regularly check the perfect function of all electrical equipment. - Only qualified personnel may remove faults or repair damage. - Only replace faulty components or equipment with original Wolf spare parts. Any damage or loss resulting from technical modifications to Wolf control units is excluded from our liability. Disposal and recycling Observe the following information regarding the disposal of faulty system components or the system at the end of its service life: Dispose of all components in accordance with applicable regulations, i.e. separate material groups correctly. The aim should be the maximum possible amount of basic materials recycled and the lowest possible environmental impact. -
Page 5: Installation
Installation Module installation The BM-Solar programming module can be integrated into the SM solar module or can be used as remote control in conjunction with a wall mounting base. When integrating the BM-Solar in the solar module, all settings are made at the solar module. The electrical connection must only be carried out by a qualified electrician. - Switch OFF the power at the solar module - Remove the facia from the solar module - Click the BM-Solar programming module into the solar module as shown in the diagram - Switch ON the power at the solar module Remote control Fitted to a wall mounting base (part no. 2744275), the BM-Solar programming unit can be used as a remote control (e.g. in the living room). -

Display level Information display In addition to the values shown on the standard display, further values for the solar thermal system can be scanned at the BM-Solar. Pressing the Info key leads to the display level. The display value A01 (solar cylinder temperature, cylinder 1) is shown. Rotary selector with pushbutton function Press Info key Example: display value A 01 Pressing the Info key again or turning the rotary selector clockwise enables all additional display values to be scanned in sequence. If the final display value is reached and the selector further is turned further, the system exits the display level and returns to the standard display. The standard display returns automatically... -

Display level Description of the display values A : 0 1 SM1: The current temperature of the solar cylinder at the level of SM1: Actual the solar indirect coil is displayed. DHW temperature Solar cylinder SM2: The current temperature of solar cylinder 1 at the level of SM2: DHW the solar indirect coil is displayed. Actual temperature Solar cylinder 1 A : 0 2 SM1: Maximum SM1: The maximum DHW temperature over the course of 24 hours DHW temperature is displayed. Solar cylinder SM2: The maximum DHW temperature of cylinder 1 over the SM2: Maximum course of 24 hours is displayed. - Page 11 Display level A : 0 7 SM1: Not installed SM1: Not installed SM2: Input E3 SM2: The current value captured by the sensor connected to input E3 is displayed. Subject to the configuration set at the SM2, this may be the buffer temperature, the actual DHW temperature of solar cylinder 2, the collector temperature of collector array 2 or the bypass temperature.
- Page 12 SM2: This indicates whether solar heating of cylinder 1 has been completed successfully within the last 24 hours. This applies if, within 24 hours prior to 14:00 h, the set DHW temperature selected at the heating appliance was exceeded by solar heating. In that case, the set DHW temperature at the heating appliance will be set to the minimum cylinder temperature (cylinder reheating blocked). This function is only available if the solar module is operated as part of a Wolf control system (for a function description, see the SM solar module manual). A : 1 8 SM1: Not installed SM1: Not installed SM2: Solar heating status SM2: This indicates whether solar heating of cylinder 2 has been Cylinder 2 completed successfully within the last 24 hours. This applies if, within 24 hours prior to 14:00 h, the set DHW temperature selected at the heating appliance was exceeded by solar heating.
- Page 13 This value corresponds to the display value x 10. This value can be reset to 0 by pressing and holding down the rotary selector for at least 10 seconds. A : 21 SM1: Not installed SM1: Not installed SM2: Solar heating status SM2: This indicates whether solar heating of cylinder 3 has been Cylinder 3 completed successfully within the last 24 hours. This applies if, within 24 hours prior to 14:00 h, the set DHW temperature selected at the heating appliance was exceeded by solar heating. In this case, the set DHW temperature at the heating appliance will be set to the minimum cylinder temperature (cylinder reheating blocked). This function is only available if the solar module is operated as part of a Wolf control system (for a function description, see the SM solar module manual). 3061916_0611...
