What to do if Bosch Controller displays temperature sensors incorrectly connected?
- RrmossSep 2, 2025
If your Bosch Controller shows that temperature sensors are incorrectly connected, it could be because a storage tank temperature sensor (SF) and mixer temperature sensor (MF) are both connected to the IPM. Remove one of the two temperature sensors (SF or MF). Another reason might be that two common temperature sensors (VF) are connected to the IPM; in this case, remove one common temperature sensor (VF).
