This illustration shows the fascia panel for the Greenstar Camray and Greenstar Camray System boilers.
An electronic 7 day twin-channel digital programmer is available as an optional extra for these boilers. This may be fitted into the removable panel on the fascia. No wiring is required as the programmer simply plugs in.
When the appliance is used for central heating, provision is made for external controls, i.e. by room and frost thermostats.
