Optional Plug-In Controls - Bosch WORCESTER Greenstar CDi Classic Series Technical Information

Optional plug-in controls

Increased SAP ratings
As well as all Greenstar combi models achieving very high SAP ratings for dwellings, the addition of an intelligent fl ow
temperature 'compensating' controller can further increase these ratings, as well as being part of the recommended best
practice, as covered by the CHeSS design standard. Load or weather compensation offers around 5% energy savings
compared to standard on/off controls.
