Observe VDE regulations [Germany] and all local regulations of your power supply utility. An omnipolar isolator with at least 3 mm contact separation must be integrated in the power cable upstream of the appliance. If using residual current protection (ground fault circuit interrupter or RCD), use a type B AC/DC-sensitive residual current protective device, as this is the only type suited to DC residual currents. Type A residual current protective devices are not suitable. Do not route sensor leads alongside 230 V or 400 V cables. Danger through 'live' electrical components. Please note: Turn 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. There is a danger of electrocution, resulting in a risk to health or death. The main terminals are "live", even when the ON/OFF switch is in the OFF position. During servicing and installation work, isolate the entire system from the power supply across all poles, otherwise there will be a risk of electrocution. Before connecting the appliance to the power supply, ensure that all electrical covers and protective devices are fully installed.

Page 85: Pv Increase
Additional functions 30.3 PV increase The PV increase function enables an adjustment in heat pump operation, e.g. when connected to a photovoltaic (PV) system to optimise on-site consumption of PV energy. An external switching command (floating contact on terminal X1 – 11/12) can increase the set temperature for heating and/or DHW, or enable the active cooling function. The heat pump can be operated using a compressor, electric heater, or both a compressor and electric heater. When configuring on-site technical devices (e.g. PV inverter), take the maximum possible power consumption of the heat pump into account (see specification).
Page 86: Smart Grid (Sg)
Additional functions 30.4 Smart Grid (SG) The Smart Grid (SG) function allows the power supply utility (PSU) to optimally adjust grid utilisation through intelligent control of consumers. Using external switching commands (floating contacts SG_0 and SG_1 on terminals X1 – 9/10 and X1 – 11/12), the compressor and/or electric heater operation can be blocked, or requested with/without an increase in the set heating/ DHW temperatures, or the active cooling function enabled.

Maintenance / cleaning 38.2 Cleaning the evaporator on the BWL-1S(B) In areas with high concentrations of dust or pollen, shorter cleaning intervals may be necessary Please alongside the mandatory annual inspection and cleaning, in order to ensure that the system note operates efficiently. Adjust the cleaning interval to suit the local conditions. The evaporator must be checked annually for dirt/contamination and cleaned if necessary. Wet cleaning with a commercially available garden hose is recommended. Contaminated fins may reduce the system's transfer performance and consequently its energy efficiency, and in the worst case scenario may result in system failure. When cleaning, ideally use a wide nozzle with a spray angle of 15° - 20°. To prevent damage to the fins, direct the water spray at the evaporator surface from the front at an angle of 90°.
