The DCN is supplied with a 3-year manufacturers warranty from Bosch. NTE offer full technical support by telephone or email on all products supplied and is backed-up the the resources of Bosch in the UK, europe and throughout the world.

The Power Consumption Factor (PCF) of contribution units connected to a CCU has a bearing on the total number of such units that can be connected. The maximum number of units quoted for a CCU on this website and in the pdf downloads is based on all units having a PCF of 1. This means that, for example, a stand-alone DCN CCU LBB 3500/05, which can accommodate 90 units of power of PCF can also accommodate 180 units of PCF 0.5.
