INSTALLATION Troubleshooting 15. Troubleshooting WARNING Electrocution Before working on the appliance, isolate it from the power supply at the control panel. Following disconnection from the power supply, parts of the appliance may remain energised for 2 minutes until the inverter capacitors have discharged. Note Observe the heat pump manager operating and instal- lation instructions.

INSTALLATION Troubleshooting 15.2 LEDs (IWS) 15.1.1 DIP switch (WP-Typ) With the DIP switch (WP-Typ), you can set the IWS to suit the relevant heat pump type. Factory setting Compressor mode with electric emergency/booster heater Note An emergency/booster heater is installed in some of the products required as accessories (see chapter “Installa- tion / Appliance description / Accessories”).
INSTALLATION Troubleshooting 15.4 Fan noise The heat pump extracts heat from the outdoor air. This causes the outdoor air to cool down. At outside temperatures of 0 °C to 8 °C, the air may be cooled to below freezing point. If, under these conditions, precipitation occurs in the form of rain or fog, ice may form on the air grille, the fan blades or the air routing pipes.
