If the domestic hot water pro-
gramme changes from a higher to a
lower specified temperature, the
water in the cylinder will not imme-
diately cool to the lower tempera-
ture, i.e. water at a higher
temperature will continue to be
available for some time. However,
the cylinder will not be reheated
until the temperature falls below
the new, lower specified tempera-
ture.
The functions of the controls and the
meanings of the symbols on the dis-
play are explained on pages 2 and 3.
