AURATON 2020 User manual

AURATON 2020
AURATON 2020 TX RX Plus
Preliminary notes
The manual includes the information on AURATON 2020
and AURATON 2020 TX RX Plus controllers.
Operation of both the controllers is identical; therefore the
whole information is placed in a single chapter. The
information related to their installation is placed in separate
sections of the manual.
AURATON 2020 TX Plus enables independent
modification of the protection code of the RX receiver
communication.
The controller is programmed in the factory to 085
code number. Nevertheless, if any communication
problem arises or another wireless temperature
controller set operates in the neighbourhood, the code
should be changed in accordance with the instruction
at page 51.

1. Installation of AURATON 2020
Note: During installation of the controller the power
supply should be switched off. It is recommended to
charge a specialist company with the installation.
1.1 A choice of proper location of the
AURATON 2020 controlle
Appropriate operation of the controller strongly
depends on its location. The location without air
circulation or in a directly insolated place results in
inappropriate control of temperature.
In order to ensure proper operation of the controller
place it on an internal wall of the building (between
the rooms).
A place of usual sojourn should be chosen, with
free air circulation.
Avoid the places in the proximity of heat emitting
equipment (TV set, heater, refrigerator) or
subject to direct insolation. Do not locate the
controller in a place adjacent to the door, in
order to avoid its vibration.

1.2 Conductor terminals of AURATON 2020
The conductor terminals may be accessed after
removing the cover of the front controller panel,
batteries, and 2 screws fixing the protection plate.
There are three terminals, marked by COM, NO,
and NC. This is a typical unipole two-state relay.
1.3 Assembly of the AURATON 2020 controller
The controller is assembled with the help of a
pattern. Bore two holes of the diameter of 6mm in
the wall. Drive the bolts and tighten the controller
with screws, the left-hand screw longer than the
right-hand one.
Note: In case of installation of a controller
provided with a floor sensor pay attention to
Figure inserted in Section 18.3, page 24.
Note: In case of a wooden wall the pins should not
be used. Drill the holes of 2.7mm instead of 6mm
diameter and fasten the screws directly to the
wood.

AURATON 2020
AURATON 2020 TX Plus
2.1 Outer view
The AURATON 2020 and AURATON 2020 TX Plus
are programmable controllers. They are able to
adjust the room temperature to the desired level 4
times within 24 hours, from Monday to Friday, and
twice within 24 hours on Saturdays and Sundays.
This enables very accurate defining the
temperature cycle within the working week, when
activity of inmates is increased, and in weekends,
during a rest time.
It allows for programming with one-minute
accuracy. At the front panel of the controller a
slidable cover is located. When open, it gives
access to the following pushbuttons:
- the time programming pushbuttons:
DAY, HOUR, MIN;
- the button of operation time of a heating system
FILTER;
- temperature programming pushbuttons:

4.5 Advanced programming.
A)
During normal operation of the controller pressing
the PROG button (as opposed to the first start after
installation of the batteries) leads to quite different
state of the display, as opposed to the point 6.
(consistent with the one previously set).
Any program may be modified, irrespective of the
other ones. Any time the PROG button is pressed,
in the intervals shorter than 10 seconds, the next
program is selected for modification.
Example 1
The PROG button pressed 3 times enables
modification of the Program No 3, in force from
Monday (MO) to Friday (FR).
Example 2
The PROG button pressed 5 times enables
modification of the first program in force for
Saturday.
12. Proceed according to the points 3
and 4.
13. Press PROG. The display will be as
follows: the indicator of the Program
2 blinks, enabling setting the second,
i.e. the last program for Saturday
(SA).
14. Proceed according to the points 3 and 4
15. Proceed according to the points 11 to 14 in
order to set the program for Sunday (SU).
16. Press RETURN or wait 10 seconds until the
controller records the changes in its memory
and resumes automatic operation.
Thus, the whole temperature cycle is programmed,
including 4 settings for 5 working days and 2
separatesettings for Saturday and Sunday. The
Table previously drawn up could be helpful in
efficient operation.

Example 3
The PROG button pressed 9 times returns the
operation to the first program for working days.
In order to avoid a mistake observe the indicators
‘2’ and ‘4’ according to the display description in the
point 5.2. The programming is completed by
pressing RETURN or waiting 10 seconds without
pressing any key.
B)
It is possible to program all 8 temperatures to the
same value, e.g. 21ºC. In such a case the equal
temperature is maintained the whole week through,
irrespective of the hours of theoretical switching
between the temperatures (no need to change the
switching time while programming).
C)
Programming sequence described in the point 7.3
may be changed, i.e. the temperature may be
programmed at first and, afterwards, the time.
D)
Programming of some or all four programs for 5
working days, or for Saturday or Sunday, is also
possible with the same hours and different
temperatures. In such a case the controller shall
maintain the temperature corresponding to a
program of lower number.
NOTE: The Program 2 of Sunday lasts until 6:00
a.m. on Monday. The Program 4 of Friday lasts until
6:00 a.m. on Saturday (this is valid for factory
settings made prior to the changes imposed by the
User).

5. Manual operation
Short pressing the MAN button causes that the
controller ceases execution of the program and
resumes manual operation. The symbol " "
appears on the display.
Required temperature, to be maintained the whole
week through, may be adjusted with the help of the
buttons " ". Automatic operation is resumed
again by pressing AUTO.

6. Energy-saving operation
This mode enables temporary setting of any
temperature for the period up to seven days with
the accuracy of 1 minute. Afterwards, the controller
returns to the automatic operation program. When
we leave home for 3 days, the room temperature
may be reduced but a certain time before our return
the automatic operation should be resumed.
In result, returning home we should not even
remark that the temperature was reduced during
our absence. We could only remark that the energy
expenses are lower.
Example
We intend to leave on Wednesday at 9:31 a.m.,
planning to return on Sunday at about 8:00 p.m.
The energy necessary for heating may be saved
during our absence.
1. Press the MAN button for about 3 seconds,
until two symbols appear together at
the display.
ECOMO
MANUAL
43 EN AURATON 2020, AURATON 2020 TX Plus - Manual operation

2. Set the temperature to be maintained during
our absence, e.g. 17ºC, using the appropriate
buttons.
3. Pressing the buttons DAY HOUR MIN (in the
intervals shorter than 10 seconds) adjust the
day and time of restoring the automatic
(programmed) operation. In this example it
could be Sunday, 2:00 p.m.
It means that the controller should resume its
automatic operation 6 hours prior to our
planned arrival and temperature of the rooms
should grow accordingly.
Note
1. The automatic operation may be resumed
anytime by pressing AUTO.
2. The required time advance of restoring the
automatic operation strongly depends on
specific properties of the object, its insulation,
the type of heating and previous reduction of
the temperature. The time advance should be
selected experimentally.
7. Antifreeze mode
This operation mode results in maintaining the room
temperature amounting to 5ºC.
1. Move the battery cover to the right.
2. Move the slider to 5ºC.
This function switched on introduces no changes in
program settings, it only deactivates them. Once
the buttons AUTO MAN PROG are pressed
an OFF indication appears at the display, giving
evidence of deactivation of these functions.
Automatic operation may be restored any time by
changing the slider to HEAT.

9. Working time meter of the heating
device
The heating device while heating the rooms does
not operate continuously. It means that the delivery
of energy is interrupted.
In some cases the information of total number of
operation hours of the heating device e.g. within a
week or month would be very helpful.
AURATON 2020 and AURATON 2020 TX RX Plus
are provided with a heating time meter, showing
integer number of heating hours (the indicator ‘3’ is
then lit at the display).
In order to use the function the meter should be
previously reset.
1. Move the battery cover to the right.
2. Press the FILTER button for at least 3 seconds,
until the meter displays 000. Record or
remember the day of the meter resetting.
8. Switching the heating device off
1. Move the battery cover to the right.
2. Move the slider to OFF.
In this mode the heating device shall not switch on,
irrespective of the time and temperature.
45 EN AURATON 2020, AURATON 2020 TX Plus - Working time meter of the heating device

After a certain time, for example one or several days,
a week, or a month, shortly press the FILTER button
again. The display will then show an integer number
of the hours during which the heating was switched
on (since the last reset). Comparison of the heating
duration with total time elapsed since the reset
allows for determining the ratio of real heating to idle
time of the heating device.
Maximal number of accounted hours amounts to
999. When the time measured exceeds 250 hours a
FILTER indication starts blinking, thus reminding of
the need to check or reset the meter.
Once the meter achieves 999 hours it stops at this
value until resetting. The heating time may be
checked any time, similarly, the FILTER meter may
be in any time reset.
Note: Is the heating operation time useless for the
user, simply ignore the FILTER button and indication
at the display.
They do not affect the operation of the AURATON
2020 and AURATON 2020 TX RX Plus controllers.
10. Controller sensitivity (hysteresis)
Sensitivity of the AURATON 2020 and AURATON
2020 TX RX Plus controllers may be adjusted to 3
available levels: 0.5ºC (±0.25), 1ºC (±0.5), 2ºC (±1).
In the factory the sensitivity level is set to 1ºC. It
means that for the controller adjusted to 21ºC it
switches the heating device on for 20.5ºC and
switches it off for 21.5ºC. Should it be changed,
proceed as follows:
1. Press the RETURN button and keeping it
simultaneously press PROG. The display
shows the indication SPA instead of the time,
and current sensitivity, e.g. 1ºC, instead of the
temperature.
2. Using the buttons adjust the required
sensitivity, from 0.5ºC to 2ºC.
3. Press RETURN or wait 10 seconds until normal
operation mode of the controller will be
resumed.

13. Putting the AURATON 2020 TX RX
Plus controller into operation for
the first time
1. Put new alkaline batteries to the AURATON
2020 RX Plus controller.
2. Connect the AURATON 2020 RX Plus controller
to the network socket and wait about 10
minutes in order to achieve the full receiver
coverage.
3. The yellow diode " " is lit - the receiver is
accessed by the transmitter. The process is
repeated each minute and lasts about 1
second. No diode signal or blinking diode
indicates insufficient coverage.
Note: Coverage of the device is strongly
affected by the materials used for construction
of the building. In an open area the AURATON
2020 TX Plus connected with the AURATON
2020 RX Plus receiver should cover the
distance up to 100m.
In buildings the coverage should reach 30m
which is equivalent to penetration through
several stories. In ferroconcrete structures the
signal is strongly damped resulting in reduced
coverage of the equipment.
Note: The AURATON 2020 TX RX Plus kit is
set to the “085” communication code, being
ready for operation upon the first installation.
Nevertheless, in case of any communication
problems between the TX controller and RX
receiver refer to Section 11 – Setting a new
communication code.
4. The red diode " " lit indicates proper
connection of the AURATON 2020 RX Plus
receiver to 230V network.
5. The green diode " " it indicates that the
executive device (e.g. a furnace) is operative.

14. Protection
1. Should any transmission disturbance due, for
example, to a strong electromagnetic impulse
or voltage drop of AURATON 2020 TX Plus
battery, prevent the AURATON 2020 RX Plus
receiver from confirming the ON or OFF
switching within 5 consecutive cycles (i.e. 5
minutes) the heating device switches off. This is
to avoid overheating of the device. After
elimination of the reason of such a disturbance
the controller resumes its normal operation.
Only in case of battery replacement
reprogramming of AURATON 2020 TX Plus
may be required, should the operation last
longer than 30 seconds.
2. The signal transmitted to AURATON 2020 RX
Plus is of digital encoded type. It means that
several AURATON 2020 TX Plus controllers
may operate in a small area without mutual
interference.
In case of any doubts please contact the dealer
or manufacturer.
15. Operation of AURATON 2020 TX
RX Plus
As the transmission undergoes only in one direction
the AURATON 2020 TX Plus emits, for security
purposes, a short encoded signal every minute with
a view to confirming the required state of the
AURATON 2020 RX Plus receiver. This time interval
is permanently set for the microprocessor, no
change is possible.
Note: The controller may cooperate with an electric,
gas, or oil device of the power exceeding load
capacity of the terminals only through an
intermediate switch of the power and operation
suitable for the end device. In such a case please
consult the dealer or guarantor.
Note: Avoid high induction and capacity loads as
they result in burning the transmitter contacts out.
