Options
At the left
and
right
hand
sides of
the
display is a rectangular line corresponding to one
of
the
four timing statement options. These are;-
OFF
- OFF at all times.
TWICE
-
ON
for two periods each day.
ONCE
-
ON
for one period each
day
(On 1 to OFF
2).
ON
-
ON
at
all times.
To
choose one of the four options press & release
the
SELECT button.
As the programming for
HW
and
CH
are
independent
of
each other the left
hand
side
of
the
display can
vary
from that
on
the right hand side.
The normal switching times can
be
overridden
by
pressing the advance button. This will switch
the
programme
between
ON
& OFF.
There
is
no
need
to
press
the
advance
to
return
to
the
programme
as it will be automatically returned at the next switching time.
Helpful hints for setting the programmer and its use.
When using the +
or
- buttons to set the time.
If
they are pressed & released the display will
change at the rate of
10
minutes
per
press,
but
if
the buttons are held in the clock will 'run'.
OFF2 cannot be set more
than
23
hours
50
minutes after the
ONI
time.
The switching time periods have to be set in sequence of
ONl,
OFFl, ON2
and
OFF2.
If
at
any
point it is wished to start again press
SET
and
+ buttons
at
the same time.
If
this is
done
the
display will return to 12.00
am
and
the standard time programme. The clock will be required to
be
reset
at
the
correct time.
If
when
setting
no
button
is pressed after one minute the programmer will revert to its normal
opperating mode.
If
in
summer
only the
Hot
Water service is required then repeatedly press the
CH
Select
button
until the display indicates
CH
OFF mode.
