In Gravity (G) systems, the central heating cannot be
operated without the hot water. In this case with central
heating in AUTO, the only selectable modes for hot water
are ON, ONCE or AUTO.
The operating mode functions are:

ONCE On for one period per day (from Programme 1 ON to Programme 3 OFF)

In fully pumped and controlled systems (P), the central heating and hot water can be operated
independently, but as previously mentioned, with gravity fed hot water systems (G), the central
heating cannot be operated without hot water.
