Centroller 3000+ Instructions For Use

CENTROLLER 3000+
INSTRUCTIONS FOR USE
Introduction
The Centroller 3000 is a micro-
processor based controller for
domestic Hot Water and Central
heating Systems which allows the
user to programme four
consecutive periods in 24 hours.
During each of these periods a
different room temperature can be
set.
One hot water temperature can also
be set and controlled during the
selected periods.
In addition a separate 'Hot water Boost'
control allows the user to
heat a thankful of water to the
programmed temperature,
independent of any other
programme that might be set.
A. Programming
For the Centroller to be fully operational, it is
necessary to programme it with the following
information:
i) The 'actual time'; see section B
ii) The four times at which the room
temperature changes are to take place; see
section B
iii) The room temperature required during
each of the four time periods; see section C.
iv) The hot water temperature; see section D.
After setting the time and temperature information
into the programme the HEATING and HOT
WATER selectors may be used to give variations
to the programme; see section E and F.
For example, the heating may be limited to day
time only and water heating switched on only
during the morning and evening periods. Full use
of the programme can give 16 variations.
Completely independent of any programme that
might be set, a 'Hot Water Boost' button is
provided. This boosts the hot water temperature
until one thankful at the demanded temperature is
available, when the boost is disengaged; see
section H.
B. Programming times
Notes:
i) Unless a programme setting entry has
been made within the last 15 seconds, the
display indicates the time of day in hours
and minutes and in the 24 hour notation
(00.00 – 23.59).
ii) A four figure time must always be keyed in
before the Centroller accepts it as a new
time. If less than four figures are keyed in, the
figures entered will be displayed for 15
seconds and then the display will revert to
show 'actual time'. The Centroller will
continue to operate at the previous time
setting.
iii) Impossible entries are ignored by the
Centroller and the display will remain
Unchanged after such an entry. Examples of
Impossible time entries are:
a) Keying in a first digit greater than 2 or
b) A minute entry grater than 59
If an impossible entry has been attempted,
press the correct key and carry on with the
time setting
iv) Before any programme changes are made
ensure that the Heating and Hot Water selector
are set to the 'on continuous' position.
Setting 'Actual Time'
1. Press the 'actual time' push button.
2. Key in the time to the nearest minute. If
the time is 9.37 am, press the setting keys
in the following sequence 0-9-3-7 or for
9.37 pm, key 2-1-3-7. As each number is
keyed, it will be shown in the display.
3. The clock has now been set and will
update the time display every minute.
Setting Programme Times
Note:
Programme times can only be defined in ten
minute steps. The fourth digit will always be
entered and displayed as 'O' irrespective of
which digit key is pressed.
Morning on time
This is the end of the 'night temperature'
period and the start of the 'morning
temperature' period.
Press the 'morning on time' push button.
The display will show the present programmed
'morning on time' for approximately 15 seconds
when it will revert to displaying 'actual time'.
If you wish to change the 'morning on time'
key in the new time you require before the
display reverts to 'actual time'.
The new 'morning on time' will be retained
in the Centroller's memory.
Morning Off Time
This is the end of the 'morning temperature'
period and the start of the 'mid-day
temperature' period.
Press the 'morning off time' push button and
follow the same procedure as the 'morning
on time.
Evening on Time
This is the end of the 'mid-day temperature'
period and the start of the 'evening temperature'
period.
press the 'evening on time' push button and
follow the same procedure as for 'morning
On time'.
Evening Off Time
This is the end of the 'evening temperature'
period and the start of the 'night temperature'
period.
Press the 'evening off time' push button and
follow the same procedure as for 'morning on
time.
C. PROGRAMMING ROOM TEMPERATURES
Notes:
(i) Temperatures should be set according to the
location of the temperature sensor (senstat).
If the senstat is in the living room then
Temperatures appropriate to that be set.
If it is located in the hall temperatures should be set.
Similarly any other location would require the
appropriate temperatures to be set. Your heating
engineer should have ensured that when one area is
controlled to the appropriate temperature the
living area will be controlled to the correct comfort
temperature. The Centroller will allow you
to reduce the temperature during periods when
maximum comfort is not required.
For example, a two degree reduction in the hall
temperature would generally ensure that other
heated areas were reduced by a similar amount.
British Standards suggest the following
temperatures for maximum comfort:-
Living area 21 C
Hall 16 C
Kitchen 16 C
Bedroom 18 C
ii) Before any programme changes are
made ensure that the HEATING and HOT
WATER selectors are set to the 'on
continuous' position.
(iii) A two digit temperature must always be
keyed in otherwise the Centroller will ignore
the entry. Room temperatures can
be set from 06 C to 26 C.
Morning Temperature
This is the temperature you require between
the 'morning' on time' and the 'morning off
time'.
Press the' morning temperature' push
button. The current programmed morning
temperature will be shown on the display for
approximately 15 seconds when it will revert
to actual time.
If you wish to change the 'morning
temperature' key in the new temperature
before the display reverts to actual time.
The new 'morning temperature' will be
retained in the Centroller's memory.
Mid-day Temperature
This is the temperature you require between
the 'morning off time ' and the 'evening on
time'.
Press the 'mid-day temperature 'push button
and follow the same procedure as for
'morning temperature'
Evening temperature
This is the temperature you require between
the 'evening on time' and the 'evening off
time'.
Press the 'evening temperature' push button
and follow the same procedure as for the
'morning temperature'.
Night Temperature
This is the temperature that you require
between the 'evening off time' and the
'morning on time'.
Press the 'night temperature' push button
and follow the same procedure as for
'morning temperature'.
D. PROGRAMMING HOT WATER
TEMPERATURE
Note:
Before any programme changes are made
ensure that the HEATING and HOT WATER
selectors are set to the 'on continuous'
positions.
A single hot water temperature may be
selected between 52 C and 75 C.
Press the 'hot water temperature' push
button. The current programmed hot water
temperature will be shown on the display for
approximately 15 seconds when it will revert
to actual time.
If you wish to change the 'hot water
temperature', key in the new temperature
before the display reverts to actual time. The
new 'hot water temperature' will be retained
in the Centroller's memory.
E. CENTRAL HEATING PROGRAMME
SELECTION
To select one of the four Central Heating
options, move the HEATING selector to the
Required position
