Using Override (Advance)
To advance the programme, that is to bring forward
the next ON or OFF period as shown in the example
below, press the override button for the relevant
circuit (i.e. HEATING OR HOT WATER. If both circuits
are to be advanced each circuit should be treated as
a separate function.
NB: If the RWB2 has been set for a 10 position, i.e.
gravity hot water, pressing the override will also
bring on the hot water circuit.
➧
Using Boost
Pressing this button once brings the unit ON for 1
hour. To activate BOOST push the BOOST button
adjacent to the HOT WATER or CENTRAL HEATING
selector. If both circuits are to be boosted each circuit
should be treated as a separate action.
(However if the unit has been set for a 10 position,
i.e. gravity hot water, pressing the heating boost
button will also bring on the hot water circuit). To
cancel boost press the relevant override button.
NB: This feature operates in OFF, ONCE and TWICE
modes only.

Adjusting the Clock (Dial Time)
To set the clock to the correct time of day rotate the
dial clockwise as shown by the arrow so that the
correct time is adjacent to the raised line with time
written against it. Please note the dial is a 24 hour dial
with times shown numerically at two hour intervals
and bars for hours between.
NB: Do not rotate the dial anti-clockwise as this
could cause damage to the mechanism.
