Fully Pumped or gravity System

The installer will have set the programmer to suit the installed system. This is normally a

Fully Pumped system which will allow independent control of the central heating and hot

water, however on an old Gravity system the central heating and hot water are linked so

that it is not possible to use the central heating independently. This will allow only one

common time setting for both hot water and central heating, and will become apparent

when setting the ON and OFF times as both will be indicated together.

BOOST FUNCTION - 1 HOUr TeMPOrary OverrIde (HOT WaTer ONLy)

The boost facility will allow the user to boost the hot water channel which is currently

'OFF' for 1 hour. To indicate the boost being activated BOOST will be shown on the display
