General safety instructions
All electrical connections and safety
measures have to be carried out by a
specialist in due consideration of valid
standards and VDE-guidelines as well as
the local regulations.
Important!
Disconnect from mains power before
opening.
Unauthorised attempts under voltage
may damage the control or cause
dangerous electrical shocks.
Safety measures for EMC -
compliant installation
1. Cables with mains voltage must be
generally routed separately from
sensor lines and data bus cables.
A minimum distance of 2 cm between the
lines is mandatory. Crossing of lines is
permitted.
2. When installing the thermostat a
minimum distance of 40 cm must be
maintained to other electrical utilities
with electromagnetic emissions, such
as radios, motors, transformers,
dimmer switches, microwave ovens
and televisions, loudspeakers,
computers, mobile phones etc .
3. The main connection for the heating
system (i.e. boiler – and poss.
accessories) must be designed as an
independent electrical circuit. No
fluorescent lamps or other disturbances
should be connected or connectable.
Recommended cable cross-sections
and maximum permitted cable lengths:
Fuse 16 A
Boiler room-emergency
Only connect boiler room
lighting and sockets on
independent electrical
circuits!

For the data bus line
Cross-section: 0.6 mm
Maximum permitted cable length: 50 m
Longer connecting cables should be
avoided in order to reduce the risk of
faults.
Installation of the thermostat
Mounting Location
a – for applications without room sensor
(100% weather-dependent)
If the internal room sensor is not to be
activated the unit may be mounted at
any location indoors.
b – for applications with room sensor
With the room sensor activated, the
thermostat should be mounted at a
height of approx. 1.50 m at a neutral
place, i.e. a measuring locatio n
representat ive of all rooms. It is
recommended to chose a partition wall
in the coolest day room. In order to
ensure sufficien t air circula ti o n at the
room control unit it must be mounted to
the wall so that air ca n flow behi nd it.
The thermostat must not be mounted:
– at locations subjected to direct solar
radiation (consider the position of the
sun during winter).
– close to heat-generating appliances,
such as televisions, refrigerators, wall
lamps, radiators etc.
– on walls with heating or domestic hot
water pipes or chimneys behind.
– on non-insulated outside walls
– in corners or wall recesses, shelves or
behind curtains (insufficient ventilation)
– close to doors of unheated rooms
(influence of low temperatures)
– on unsealed flush-type boxes
(influence of external low temperatures
due to the chimney effect of installation
tubes)
–
in rooms with radiators controlled by
thermostatic valves (mutual influence).

Mounting instructions
After removing the front panel by pressing
the locking plug the mounting base can be
taken off and mounted at the desired
location using the enclosed dowel pins and
screws. The data bus line must thereby be
routed through the bottom cable opening.
Maximum cable length: 50 m
Note:
For new installations, use a flush-
mounting switch box that is separated
from the rest of the electrical installation to
ensure perfect routing of cable.
Connection to the ATAG boiler
The electrical connection must be in
compliance with the terminal designation
in the unit.
A = 20
B = 21
Connection panel burner
Electrical connection
The 2-strand data bus cable is connected
to terminals A and B of the 2-pole
connection on the mounting base.
Important!
The connections are not interchangeable
and must be installed in compliance with
the identification A and B. If the two
connections are mixed up by mistake, the
display will not function.
Once the electrical connection is
completed, the thermostat is hooked in
flush at the top and folded down, until the
locking lug audibly clicks into the mounting
base.

Outdoor sensor
Mounting Location
The outdoor sensor should be mounted on
the most exposed and coldest side of the
building (north or north-east) at a height of
min. 2 m above ground.
Exception:
If the preferred living area
is situated in a different
direction, you should
choose the respective
side of the building
accordingly.
When mounting the sensor mind external
heat sources (heated chimneys, warm hot
air from air shafts, installation on black
surfaces, thermal bridges in the wall, etc.)
which could falsify the measuring value.
The cable outlet must always be directed
downwards in order to avoid the
penetration of moisture.
The outside sensor may not be mounted
close to transmitting or receiving
equipment (on garage walls close to
receivers for radio-controlled garage door
openers, amateur radio antennas, radio
controlled alert systems or close to large
scale radio transmission equipment).
Electrical connection
For the electrical installation preferably
use a 2-strand cable with a minimum
cross-section of 0,6mm
2
. The connection
is made at the 2 screw terminals inside the
sensor case and may be interchanged.
Mounting instructions
1– Route the sensor cable to the
mounting location
2– Loosen lid screws from sensor case
and remove top
3– Mount sensor base with enclosed
central fastening screw.
Use sealing ring! The cable outlet must
be directed downwards!
4– Insert the sensor cable so that the
cable jacket is fully enclosed by the
sealing lip.
5– Establish the electrical connection.
The terminals may be interchanged.
6– Place the lid and screw it firmly onto
the base. Ensure correct fit of sealing
ring.

Commissioning of the thermostat
Segment test and identification
During the first activation of the thermostat
or with each return of voltage after a
power failure, all the segments available in
the display will appear:
This is followed by the thermostat version
with type code and current software
version.
If there is no alarm present, the standard
display with date, time and current
ambient temperature will appear
afterwards.
Thermostat display will light up when one of
the keys is pressed. The light will go out
automatically when no changes are made
for about 90 sec.
An active summer switch-off is
represented by a sunshade symbol (À).
An active frost protection function is
represented by a frost symbol (Á).
Code input
Installer code
After entering the installer code all
parameters determined for the heating
specialist are released and can be edited
in accordance with the thermostat version.
Code input
In order to enter the installer code the
keys
¢
and ¤ must be simultaneously
pressed for approx. three seconds, until
the code input appears in the display.
¢
+ ¤
Each flashing digit is set by means of the
rotary pushbutton in accordance with the
code number and confirmed by pressing
the button. All other digits are entered in the
same way.
After correct input of code the
acknowledgement
INSTALLER OK
will
appear upon acceptance of the last digit,
in case of a wrong entry the message
CODE ERROR
will appear.

takes place over a period of

installer code must be
entered again.
Alarm messages
In order to be able to perform an exact
diagnosis in case of a problem the control
system is equipped with a comprehensive
fault alarm system. Depending on the nature
of the fault a corresponding fault message will
appear in the display of the thermostat.
All fault messages are transmitted by the
MCBA and are d ivided into
A – permanent faults (permanent locking) with
MCBA error cod e E-XX
or
B – temporary faults (self-eliminating locking)
with MCBA error c ode B-XX
Alarm message MCBA
Faults Locking EnX
Faults Blockage BnX
The display and processing of alarm
messages can be suppressed by using a
corresponding parameter (see Parameter
13 - SYSTEM level – Messages on
thermostat active).
Further processing of errors:
– Errors appear in the standard display of the
control
–
System errors appear in the info-level at the
corresponding info-value
–
Errors may be taken over into the error
message register (see description below).
Detailed information about errors from the
MCBA can be found in the documentation for
ATAG boilers.
Alarm message register
The thermostat is provided with an alarm
message register, which is able to hold up to
five alarms. The alarms are displayed with
date, time, and nature of fault (error number),
the errors are polled in the sequence of their
occurrence in the level
ALARM
.
The last (= latest) alarm is prioritized at first
position, alarms that have arrived before are
pushed down one position on the list at every
new alarm. Upon arrival of a new alarm the
fifth alarm will be deleted.
Alarm messages of the MCBA
The alarm messages of the MCBA are
a special case.
Because these alarms
are external faults, they are saved in
the alarm message register of the
thermostat as long as the burner is
not re-installed.
