Our Greenstar Comfort+ II RF is a simple to use wireless control that allows you to access all control functions at a single, easily accessible location. The control allows you to set up to six adjustable heating control and three hot water timings per day, using our simple temperature dial and an easy to use navigation menu. The Greenstar Comfort+ II RF programmer, part of the Comfort+ control family, comes with our first industry leading ‘RF Key’ which simply plugs into the boiler and is pre-paired with the programmer. The Comfort+ II RF is currently only compatible with the Greenstar Lifestyle range and Worcester 2000.
