The Burner; The Programmer; What It Does; Functions - Rayburn 660 User Instructions

THE BOILER
The temperature of the hot water supplied can be
adjusted by means of the boiler thermostat knob. This
knob can also be used to turn the boiler off.
To inhibit internal corrosion of the boiler heat exchanger it
is important not to operate the boiler below 60°C.
An ideal setting for summer hot water; and to keep the
temperature above 60°C, can be achieved using the
'ECO' setting.
'ECO' SETTING
The 'ECO' setting on the boiler is a range at which the
boiler operates at maximum efficiency.
The boiler thermostat knob is situated behind the control
door (See Fig. 2). Turn the knob clockwise to increase the
temperature of the water.
Should your heating water system be of an unvented
design i.e. Pressurised System. It is important not to keep
resetting the boiler safety cut-out as this may indicate a
loss of secondary water.
Check also your system pressure gauge.
FROST PRECAUTIONS
In the event of the boiler being OFF for long periods
during very cold weather, the advice of your installer
should be obtained.

THE BURNER

If a fault occurs on either burner then a fault code is
displayed and shuts down the part of the appliance with a
fault (cooker or boiler).
This can be re-set after 1 minute by pressing the REPEAT
button.
In the event of repeated failure switch off the oil and
electrical supply to the appliance and contact the
installer/service engineer.

THE PROGRAMMER

WHAT IT DOES

The Rayburn programmer is a 7-day 2 event programmer
which allows the user to set 2 periods of the day in which
the cooker will turn on and then off, A typical example of
how this may be used is 'on' for use in the morning and
then 'off' when going out, and then 'on' if needed for
cooking later in the day and then 'off' when cooking is
finished.
The programmer can be set for different time each day
(e.g. morning and evening). However, as many people
have a similar routine through the working week, there is
a repeat function which allows the setting from the
previous day to be copied.
However, it may still be set each day differently.

FUNCTIONS

The AUTO/MAN functions allow the user to turn the
cooker on, by simply turning the knob to the required
cooking mark temperature, or by having it turn on at 2 set
periods within the day.
The minute minder function works as a countdown timer
to ease with cooking. When the timer has counted down
the display will flash 00:00 and a buzzer will sound.

SETTING INDIVIDUAL DAYS

To allow the user to change an individual day without
having to run throughout the entire week, there is the
ability to change just one day (e.g. days holiday) without
altering the previous settings.
