The NCN0422 PCB will be replaced by the NCN0422.1 component in new devices and during service work. This component transmits the radio signal to trigger the pump in the connected tank unit.

The new NCN0422.1 component is narrower than the old model. The previous PCB will no longer be fitted, and is also no longer available. If you order using the old item number you will automatically receive the new unit. You can download the operating manual for the BÜHNEN HB 910 in our service area.
