How do I troubleshoot a defective tank temperature sensor on my Bosch FW 200 Controller?
If your Bosch Controller indicates a defective tank temperature sensor, it means the tank temperature sensor (SF) connected to the IPM is defective. Check the storage tank temperature sensor (SF) and replace it if required.
What should I do if the external heating supply temperature sensor is defective on my Bosch FW 200 Controller?
If your Bosch Controller displays that the external heating supply temperature sensor is defective, it means the common temperature sensor (VF) connected to the IPM is defective. Check the common temperature sensor (VF) and replace it if necessary.
How to fix a defective mixer temperature sensor on a Bosch Controller?
If your Bosch Controller indicates a defective mixer temperature sensor, it means the mixer temperature sensor (MF) connected to the IPM is defective. Check the mixer temperature sensor (MF) and replace it if necessary.
What causes a Bosch Controller to be unable to save parameter settings?
If your Bosch Controller is unable to save parameter settings, it may be because a BUS device is configured but not available at present. Check the system structure and configuration, adjust as necessary, and reset parameters on the remote control.
Why is my Bosch Controller unable to save parameter settings?
If your Bosch Controller is unable to save parameter settings, it could be because a BUS device is configured but not currently available. Check the system layout and configuration, modify if necessary, and then set the parameter again.
What to do if Bosch Controller displays temperature sensors incorrectly connected?
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).
How to resolve a defective room temperature sensor fault on a Bosch FW 200 Controller?
If your Bosch Controller indicates a defective room temperature sensor, it could be due to a circuit break on the room temperature sensor built into the FW 200/FB 100. Identify defective controls or remote control and replace.
What causes a Bosch FW 200 to display a solar pump seized or air in system fault?
If your Bosch Controller displays a 'Solar pump seized or air in system' fault, it could be due to a few reasons. The solar pump (SP, PA, or PC) might be sticking due to a physical blockage. To resolve this, unscrew and remove the slotted screw on the pump head and use a screwdriver to release the pump shaft. Do NOT strike the pump shaft with the screwdriver. Another cause could be air in the solar thermal system. Bleed the solar system and top up with heat transfer fluid if necessary. It is also possible that the secondary circuit pump (PD) is sticking due to a physical blockage; in this case, unscrew and remove the slotted screw on the pump head and use a screwdriver to release the pump shaft. Do NOT strike the pump shaft with the screwdriver.
Why doesn't my Bosch FW 200 heat up the domestic hot water tank?
If the domestic hot water tank is not heating up, it might be because the hot water temperature control on the boiler is set too low. Try setting the hot water temperature control higher. Another possibility is that the supply temperature controller on the boiler is set too low; turn the supply temperature control on the boiler clockwise as far as it will go.
What to do if my Bosch Controller shows an internal fault?
If your Bosch Controller is showing an internal fault, there could be several reasons. An incorrect BUS device might be connected, so identify and replace it. Two identical IDs might be set on the IPM; switch the system off and correct the ID. If thermal disinfection via IPM failed, turn the supply temperature control on the boiler clockwise as far as it will go. If the ISM is not responding, check the BUS connection and repair any circuit breaks if necessary. Check parameter settings and readjust them as necessary. Identify defective controls and replace.
