What it is
The Worcester Bosch 7747010612 is a Basis Controller BC10, the control unit supplied for EMS (Energy Management System) bus appliances in the GB162 family. It is listed by the manufacturer as a casing assembly, meaning the controller is supplied as a complete housed unit rather than a bare board. In service it provides the interface between the appliance and the heating system controls, handling the EMS communication and operating settings for the boiler.
Signs this part needs replacing
- The controller display is blank or fails to illuminate when the appliance is powered.
- Buttons or dials do not respond, or settings cannot be changed.
- The boiler ignores heating or hot water demands that are being sent from the controller.
- Fault codes relating to the control or EMS communication appear on the appliance.
- Operation is intermittent, with the controller dropping out and returning during a call for heat.
Before you order
- Confirm the appliance model and serial number against the compatibility list, as the GB162 range was produced in several output sizes.
- Check the number on the existing controller and compare it with 7747010612 and the previous number 63045731 before ordering.
- If the controller is being replaced as part of a wider repair, inspect the connecting lead and plug for damage at the same time.
