The Advance Function

The ADVANCE function allows the user to move to the next
ON/OFF programme for a "one off" event, without having to
change the programme or use the ON or OFF buttons.
N.B. The ADVANCE function is only available when the
programme is in AUTO or ALL DAY operating modes and
the slider must be switched to RUN.
To Advance Central Heating/Hot Water
1. Press the ADV button. This will turn the Central Heating/
Hot Water ON if it is in an OFF period and OFF if it is
in an ON period. The word ADV will appear to the left
hand side of the LCD display.
2. It will stay in this state until either the ADV button is
pressed again, or until a programmed ON/OFF period
commences.
The +HR Boost Function
The +HR function allows the user to have up to 3 hours of
extra Central Heating or Hot Water, without having to change
the programme.
N.B. The +HR function is only available when the programme
is in AUTO, ALL DAY or OFF operating modes and the
slider must be switched to RUN. If the programmer is in
AUTO or ALL DAY mode when the +HR button is pressed
and the resulting time of the boost overlaps a START/ON
time, the boost will disengage.
