What to do if DHW Temperature Sensor is defective on Bosch Control 8313?
- J
  Jaime TorresAug 31, 2025
  If the DHW (Domestic Hot Water) Temperature Sensor is defective on your Bosch Control Unit, start by checking the sensor port to ensure it's correctly connected. If DHW was selected, inspect the sensor mounting on the DHW cylinder. If these steps don't resolve the issue, the temperature sensor, module, or the control unit itself might be faulty. If so, consider replacing the temperature sensor, module, or control unit as needed.

  Stacie ReedAug 29, 2025
  A defective remote control heating circuit sensor in your Bosch Control Unit can stem from several issues. The remote control itself might be incorrectly connected or defective; in this case, check its function and connection, and also verify its addressing. The temperature sensor could be incorrectly connected or faulty. Check the connecting cable to ensure it's properly connected. The remote control may have been incorrectly allocated, so replace the remote control and function module.

How to fix a defective outdoor temperature sensor on a Bosch Control 8313?
- C
  Carrie MercerAug 28, 2025
  If the outdoor temperature sensor on your Bosch Control Unit is defective, it might be incorrectly connected, not connected at all, or actually defective. Begin by checking whether the outside temperature sensor is connected to the correct control unit (specifically, the control unit with address 0 in systems with multiple heat sources). Also, check the communication with the control units. If problems persist, consider replacing the outside temperature sensor or the central module.

What to do if thermal disinfection failed on Bosch Control Unit?
- L
  lindaweissAug 27, 2025
  If thermal disinfection fails on your Bosch Control Unit, it could be due to several reasons. The heat source output might be insufficient because other heat consumers are demanding heat during disinfection. Try selecting a time for thermal disinfection that doesn't overlap with additional heat requirements. Also, check the function of the temperature sensor and the primary pump, as the temperature sensor or the cylinder primary pump could be incorrectly connected or faulty. In such cases, you may need to replace the temperature sensor and primary pump. The FM-MW module or the control unit itself could be faulty, potentially requiring replacement. Finally, consider if the draw-off rate during thermal disinfection is too high.

  Travis HaleAug 27, 2025
  A high flue gas temperature in your Bosch Control Unit can be caused by a soiled heat source (clean the heat source) or a faulty flue gas temperature sensor (check sensor connection and function).

What to do if DHW remains cold with Bosch Control Unit?
- S
  Scott RodriguezAug 26, 2025
  If the DHW (Domestic Hot Water) remains cold when using your Bosch Control Unit, there might be a few potential causes. The cylinder primary pump could be faulty, so check if the function is set to Auto. Alternatively, the FM-MW module might be defective; in this case, check the function of the temperature sensor and the primary pump. It's also possible that more DHW is being used than heated; if this is the case, consider replacing the module or control unit.

How to fix a dark display on my Bosch Control Unit?
- C
  Christian HensonAug 25, 2025
  If the display on your Bosch Control Unit is dark, it could be due to several reasons: the heating system emergency stop switch might be off (switch it on), the control unit itself might be switched off (switch it on), the control unit safety equipment may have been triggered (push in the pin), or a safety device has been triggered (check the circuit breaker).
