General safety instructions
All electrical connections and safety
measures have to be carried out by a
specialist in due consideration of valid
standards as well as the local regulations.
The electrical connection has to be done
according to the specications of the
respective boiler manufacturer.
Safety measures for electricalcompliant installation
1. Cables with 120 V voltage must be
generally routed separately from
sensor lines and data bus cables.
A minimum distance of 0.8 in (2 cm) between
the lines is mandatory. Crossing of lines is
permitted.
2. When installing the room control unit a
minimum distance of 15.75 in (40 cm)
must be maintained to other electrical
utilities with electromagnetic emissions,
such as power contactors, motors,
transformers, dimmer switches,
microwave ovens and televisions,
loudspeakers, computers, mobile
phones etc.

WARNING
Indicates an imminently
hazardous situation
which, if not avoided,
could result in death or
serious injury.
WARNING
Disconnect power before opening. Making
connections under voltage may damage the
control or cause dangerous electrical shocks.
120 volts is supplied to the control.
The main connection for the heating
system (i.e. boiler - control unit) must be
designed as an independent electrical
circuit. Do not connect uorescent lamps
or other electrically powered devices which
could be a source of electrical interference.
Even the possibility of such
connections/interference should be ruled
out.
4
4. It is suggested to use a shielded cable
for all installations.
5. The shielding of the cable has to be
connected with earth potential, i.e.
boiler covering, connecting terminals for earth potential etc. Multiple
grounding is not permitted (humming
loop).
In star shaped networks it is not
permitted to ground cables on both
sides. They should be grounded in the
center.
6. The outside sensor may not be
installed 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).
Recommended cable cross-sections
and maximum permitted cable lengths:
A – Sensor lines
For all low voltage cables such as
sensors, external selectors, bus and
analogue in- and outputs, heat requiring
by means of external contact, modem
connection cables, etc.: 0.0008 in (0.5 mm )
2
Maximum permitted cable length: 164 ft
(50 m).
Longer connecting cables should be
avoided in order to reduce the risk of
electrical interference.
B – Data bus lines
Recommended cable:
J-Y(St)Y 2 x 0.0009 in (0.6 mm )
2
Maximum permitted cable length: 164 ft
(50m)
Longer connecting cables should be
avoided in order to reduce the risk of
electrical interference.

Installation of the room control
unit
Mounting location
a – for applications without room sensor
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
The activated room sensor should be
xed at a height of approx. 4-5 ft (1.2-1.5 m)
at a place most representative of all
rooms. It is recommended to choose a
partition wall in the coolest day room. In
order to ensure sucient air circulation
at the room station, it must be mounted
to the wall with a gap in between.
The unit 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 (insucient ventilation)
– close to doors of unheated rooms
(inuence of low temperatures)
– on unsealed ush-type boxes
(inuence of external low temperatures
due to the chimney eect of installation
tubes)
– in rooms with radiators controlled by
thermostatic valves (mutual inuence).
Mounting instructions
After removing the front panel by pressing
the locating lug the wall mounting base
can be taken o 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 gland.
Recommended connecting cable:
J-Y(ST)Y 2 x 0.0009 in (0.6 mm ) (18 AWG /
2 conductor twisted pair shielded cable)
2
(2 wires not in use).
Maximum cable length: 328 ft (100 m)
Note:
For new installations, a ush-mounting
switch box is recommended to ensure
perfect routing of the cable.

Electrical connection
The 2-strand data bus cable is connected
to terminals A and B of the 2-pole terminal
strip on the bottom plate.
Socket (unit removed)
Important!
The connections are not interchangeable
and must be installed in the socket in
compliance with the identification A and B.
Once the electrical connection is
completed, the room control unit is hooked
in flush at the top of the wall mounting
base and folded down until the locking lug
audibly clicks into the wall mounting base.
Electrical connection at
boiler
The electrical connection depends on the
type and version of the respective heating
generator and takes place directly at the
terminals A and B in the corresponding
boiler control or interface.
Further detailed information can be found
in the documentation for the
corresponding boiler.

Accessories
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. 79 in (2 m) above ground.
Exception: If the preferred living area is
situated in a dierent
direction, the outside sensor
should be mounted on the
respective side of the building
accordingly.
When mounting the sensor consider 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.
Installation and electrical connection
1– Route the sensor cable to the chosen
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. To
this end, preferably use a 2-strand
cable with a minimum cross-section of
1 mm
2
(18 AWG). The connection is made
at the 2 screw terminals inside the
sensor case and may be interchanged.
6– Attach the lid again and screw it
rmly onto the base. Ensure correct t
of sealing ring.

Alarm messages
In order to be able to perform an exact
diagnose 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 alarm
message will appear in the display of the
room control unit.
The display and processing of logic alarms
is deactivated in the factory and can be
activated in the SYSTEM level by enabling
Parameter 13 (= Logic alarm). The entry
into the level selection and the entry into
the levels is shown in the Parameter
synoptic (see page 11).
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
opposite).
Detailed information about errors of the
boiler can be found in the
documentation of the boiler.
Alarm messages from boiler control
If boiler controls are used in the respective
boiler, the alarm messages are
divided into:
A - permanent faults (permanent locking)
with error code E-XX
B - temporary faults (self-eliminating
locking) with error code B-XX
Fault category A Locking E-XX
Fault category B Blockage B-XX
Alarm message register
The room control unit is provided with an
alarm message register, which is able to
hold maximum 20 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 latest (= up-to-date) alarm is
prioritized at first position, alarms that
have arrived before appear in the order of
their occurrence. Upon arrival of a new
alarm the last (20.) alarm will be deleted.
Alarm messages from condensing boiler
controls represent a special feature. If
enabled (SYSTEM parameters 27 and
28), these will be written into an own alarm
message memory.
