The Buderus 3000 may only work when the outdoor sensor is disconnected because there could be an issue with the sensor itself. If the sensor is malfunctioning or sending incorrect readings to the system, it could be causing the boiler to not operate properly. Disconnecting the sensor may allow the boiler to operate based on its internal settings rather than relying on potentially faulty external input. It is important to have the sensor checked and potentially replaced to ensure the system operates efficiently and accurately. **

No, the freezer compartment of a refrigerator cannot be disconnected in order to only use the cooling part. The freezer and cooling compartments are interconnected and rely on the same refrigeration system to function properly. Disconnecting the freezer compartment would disrupt the overall functionality of the refrigerator and could potentially cause damage to the appliance. If you only need the cooling part, you can simply adjust the temperature settings to a higher setting to minimize the cooling in the freezer compartment. **

Yes, there are RCDs (Residual Current Devices) that can be installed in a TN-C (combined neutral and protective earth) network system where only the live conductor is disconnected and not the combined N and PE conductor. These RCDs are known as Type B RCDs, which are designed to provide protection against both AC and DC residual currents. Type B RCDs are suitable for use in TN-C systems and can disconnect the live conductor without affecting the combined N and PE conductor, providing an additional level of safety in the electrical installation. **

When your PS4 controller is only blinking white after using it at your friend's place, it may indicate that the controller needs to be reset. To reset the controller, you can locate the small reset button on the back of the controller and press it with a paperclip or similar tool. After resetting the controller, try connecting it to your PS4 again using the cable. If the issue persists, it may be a compatibility issue with your friend's console, and you may need to re-sync the controller with your own PS4. **
