HOW CAN YOU LOWER YOUR ENERGY CONSUMPTION?
Congratulations on purchasing the Nobø Orion 512. In these instructions for use we will tell you how
you can use the Orion 512 to control your house's electrical heaters, floor/ceiling heating etc., in such
a way that you can considerably reduce your heating costs while retaining the same heating comfort.
You can also use the Orion 512 to control other electrical equipment such as engine heaters, TVs,
radios, lights etc. Among other things, it enables you to make your house look inhabited when you are
not at home.
NETWORK SIGNALLING
The Orion 512 sends its control signals along the house's normal wiring network. Receivers are fitted
to the electrical equipment which is to be controlled. The receivers switch the heaters and other elec-
trical equipment ON and OFF at times chosen by you. The time can be set at intervals of one hour 24
hours of the day.
DIVISION INTO ZONES
The Orion 512 can control up to 12 independent zones. A zone is one or more rooms or heaters/appli-
ances, which follow(s) a certain program in the course of 24 hours. Every zone can be programmed
individually for every day of the week. There are thus 12 different programs for heating and other
functions. The number of heaters/appliances in each zone is not restricted.
CONTROLLING HEATING
If you have installed modern Nobø heaters, you must remember to set the comfort (right slider) and
economy (left slider) thermostats to the required temperatures. If you have heaters with a built-in,
fixed set-back function, the set-back will be limited to 5-7
o
C depending on the make. Heaters with a
cable and plug have no restriction on the temperature during economy periods. For ceiling/floor hea-
ting we recommend that the heating be controlled by Nobø's VENUS TR36 room thermostat for com-
fort and economy temperatures. It has a built-in receiver for the Orion 512.

DESCRIPTION OF THE ORION 512
FUNCTION SWITCH
The FUNCTION SWITCH "1" in the position "SET CLOCK" is used when first
starting up the Orion 512, after the power has been disconnected for more
than 14 days or when sending a test signal. The position "SET PROGRAM"
is used when first making your control programs or when changing them at a
later stage. The position "OPERATION" is the position in which the switch
should be during normal use.
DISPLAYS
The CLOCK DISPLAY "2" shows the time in hours and minutes. The ZONE
DISPLAY "3" shows the zone for which the program in "5" applies. The ROW
OF LIGHTS FOR THE DAYS OF THE WEEK "4" indicates with a yellow light
the day of the week for which the program in "5" applies.
The PROGRAM DISPLAY "5"consists of a row of lights with 24 light seg-
ments. Each segment corresponds to one hour and the display shows a
complete program for 24 hours with red lights in the comfort temperature
periods and green lights during economy temperature periods.
OPERATING BUTTONS
The DAY - HOUR - MINUTES BUTTONS "6" are used to set the day and
time in the Orion's clock. The ZONE BUTTON "7" is used to select the zone
(1-12) for which a program is to be made or which is to be overridden. You
use the red and green PROGRAM BUTTONS "8" to set the control program
you require. The CANCEL BUTTON "9" is used to correct incorrect entries
during programming or to cancel overrides. The COPY BUTTON "10" is
used to copy a 24-hour program from one day to another day or from one
zone to another zone when the programs are the same. The red and green
CONSTANT OVERRIDE BUTTONS "11" are used when you want long-term
comfort (red) or long-term reduced (green) temperatures in one or more
zones. Does not affect the program entered. SEQUENCE OVERRIDE "12"
is used for short-term changes to the current program sequence. It automati-
cally switches back to the program at the next change in level. The STATUS
BUTTON "13" shows the current situation (comfort/economy) in all 12 zones
simultaneously.
RESET BUTTON ’’14’’ is used to zeroise the ORION
512 if the processor has frozen and the unit cannot
be used.
Freezing may be due to overvoltage in the mains
following power failure or lightning strike etc. Use a
pen or other sharp object.
OPERATING THE ORION 512
SETTING THE DAY AND TIME
The programming of the Orion 512 applies for a period
of one week. Therefore, you must first set the correct
current time. All subsequent weeks then follow the
same program.
1. Set the FUNCTION SWITCH "1" to the position
"SET CLOCK"
2. Press the DAY BUTTON "6" until the right day of the
week lights up in the ROW OF LIGHTS "4".
3. Set the correct time in the CLOCK DISPLAY "2" by
pressing the buttons HOUR and MINUTES "6".
NB! The time accuracy is ± 10 min. per year and is
independant of the frequency (50/60 Hz).
PROGRAMMING
A program means an indication of how many of the 24
hours of the day and night are to be set for comfort tem-
perature (for example 22
o
C) and how many hours are to
be set for economy temperature (for example 15
o
C).
The program chart on the next page can be used to
give an overview of ZONES and PROGRAMS. Use
your own symbols for comfort and economy temperatu-
res and mark the periods in the diagram. Programming
will then be much easier to carry out afterwards.
EXAMPLE:
X = 22
o
C (ON)
O = 15

USER INSTRUCTION
SETTING THE PROGRAM
Move the FUNCTION SWITCH "1" to the position "SET
PROGRAM". The unit will now automatically switch to
zone 1 in the ZONE DISPLAY "3" and Monday in the
ROW OF LIGHTS FOR DAYS OF THE WEEK "4", and
where all LEDs in the PROGRAM DISPLAY (5) are red
(new units) or show an earlier chosen program.
The programming can now begin. Each time you press
the GREEN PROGRAM BUTTON "8" a green bar of
light will light in the PROGRAM DISPLAY "5". Pressing
the red button produces a red light. Follow the program
selection which you have prepared in the program chart
and remember to "fill in" all 24 segments. When
Monday has been programmed, press the DAY BUT-
TON "6" so that the lamp for Tuesday lights up. Then fill
in the 24-hour program again. Continue like this until all
7 days have been programmed. Then press the ZONE
BUTTON "7" until zone 2 is shown in the ZONE DIS-
PLAY "3". Set Monday again with the DAY BUTTON "6"
and repeat the procedure for zone 2 and then the other
zones which are to be used.
If you wish to DELETE all of the existing programs, this
is done in the following manner:
1. Move the FUNCTION SWITCH(l) to the position SET
PROGRAM.
2. Press the DAY BUTTON(6), the GREEN PROGRAM
BUTTON(8), the ZONE BUTTON (7), the CANCEL
BUTTON (9) and the COPY BUTTON (10) simultan-
eously.
CANCEL
If you make an incorrect entry during programming, an
unfinished program can be deleted by using the CANCEL
BUTTON "9". The Orion 512 will then display the last
selected program in the PROGRAM DISPLAY "5" and
the programming can start again. See also the section
on OVERRIDE.
COPYING PROGRAMS
If one or more zones are to have the same program for
several days in the week, you can save time and effort
by using the COPY BUTTON "10" to copy the 24-hour
program displayed in the PROGRAM DISPLAY "5".
