2. Safety notes
2.1 Correct use 2.2 Denition of the warning notices
WARNING
Warning symbol and signal are
indicating a dangerous situa-
tion with moderate risk which
may lead to death or serious
injury if not avoided.
NOTICE
Signal word (without warning
symbol) indicating a possible
danger to property.
The Oventrop system controller "Regtronic
RD-W" serves the control engineered
integration of "Regudis W" dwelling
stations into the heat supply. It provides for
a heating water temperature according to
requirements in the buffer storage cylinder
(storage cylinder loading control) and the
supply pipe of the riser for the connected
"Regudis" dwelling stations (heating circuit
control). The system-specic parameters
for an adaptation of the control to the
requirements can be entered via a user
interface.
Any use with dwelling stations of other
manufacturers is not allowed.
On principle, the controller must only be
used in a technically perfect condition, ac-
cording to its intended use and in complian-
ce with these operating instructions.
These installation and operating instruc-
tions show warnings which are displayed
by symbols. The symbols are linked to sig-
nal words which dene the seriousness of
the danger which arises from a situation.
CAUTION
Warning symbol and signal are
indicating a dangerous situ-
ation with low risk which may
lead to minor or moderate in-
jury or damage to property if
not avoided.

Safety notes "Regtronic RD-W"
2.3 Residual dangers
The following residual dangers for persons
and property exist during installation and
operation:
WARNING
Danger to life due to electric
shock!
• Opening of the controller casing
and all electrical connections must
only be carried out by a qualied
electrician.
• The following 5 safety
regulations must be observed
during installation and cabling:
- Disconnect
- Protect against accidental
restart
- Check that no voltage is
present
- Earth and short-circuit
- Cover adjacent live parts
• Please make sure that the
controller can be disconnected
from the power supply with an all-
pole disconnecting device (plug/
socket or 2-pole circuit breaker)
• The local safety directive must be
observed.
• Installation must only be carried
out in dry indoor areas.
• The low voltage connections
(e.g. sensor connections) must
not be mixed up with the 230 V
connections.
• Newly installed controllers must
only be energized once cabling of
all system components has been
carried out.
• Completely disconnect the
controller from the power supply
before removing any connected
system components (e.g. for
maintenance and repair).
CAUTION
Risk of burns due to hot
components and pipework!
A modication of the parameter settings
may lead to very high ow temperatures
in the supply riser. There is a risk of
burns from hot surfaces.
• Wear safety gloves during
installation and maintenance, if
required.
• When installing a new heating
system, the pipework has to be
insulated.

3.2 Control of "Regudis" dwelling stations
The Oventrop system controller "Regtronic
RD-W" (1) serves the control engineered
integration of dwelling stations "Regudis W"
into the heat supply.
The controller provides for a heating water
temperature according to requirements
in the buffer storage cylinder (6) and the
supply pipe of the riser supplying the
connected "Regudis" dwelling stations.
The stations require a permanent differential
pressure of at least 300 mbar and a
minimum temperature in the supply pipe.
The controller activates the heat generator
(7) and the loading pump (8) in such a
way that the buffer storage cylinder (6) is
loaded with as constant a temperature as
possible. Depending on the heating water
temperature in the buffer storage cylinder,
loading is started or interrupted.
The differential pressure (5) and the ow
and return temperatures (4) are detected
by sensors in the heating circuit riser. Based
on the detected values, the riser pump (3,
differential pressure) and the mixing valve
(2, ow temperature) are activated by the
controller (1).

This system illustration shows all possible control tasks. Control engineered subtasks may,
however, also be carried out by the system controller (1). Loading of the buffer storage
cylinder can, for instance, also be carried out by a control integrated in the heat generator.
In- and outputs at the system controller (1) which are not in use remain free!

out by the riser pump (3), a differential
pressure sensor (5) is not required.

3.2.1 Buffer storage cylinder loading
Loading of the buffer storage cylinder
with as constant a loading temperature as
possible results in the following advantages:
• optimised storage cylinder loading
• low return temperature to the heat
generator
• fewer burner starts
Depending on the system constellation,
distinction is made between the following to
variants of storage cylinder loading:
• 0-10 V activation
• Two point activation (volt free)
3.2.2 Riser control
The supply of heat to the connected dwelling
stations according to requirements is
guaranteed by the riser control. The actual
temperatures in the supply and return pipe
are constantly detected by two sensors
(4) and are transmitted to the controller (1)
which activates the motor-operated mixing
valve (2) on this basis.
If, for instance, the temperature in the return
pipe of the riser drops signicantly as water
is drawn off at several draw off points in
parallel, the mixing valve (2) will be fully
opened temporarily, i.e. colder return water
will no longer be added to the supply
pipe in order not to undercut its required
minimum temperature. An excessive ow
temperature is avoided by adding return
water to the supply pipe.
The current differential pressure is
detected by another sensor (5). If the
differential pressure in the return pipe drops
quickly, an immediate correction leading to
a short-term increase of the ow pressure
during an adjustable period will be carried
out by the riser pump (3).

Illustr. 16
This message indicates that the connection
to one or several sensors is interrupted,
has a short circuit or does not exist.
It must be observed that this message
does not necessarily indicate an error. It
is also displayed in case of an incomplete
installation (see installation instructions
doc. no. 134209380). This might be
intentional if the controller is, for instance
used for the control of only sections of the
heating system.
The sensor which does not provide values
or is not connected can be detected via
Controller settings 
Messages. Illustr. 17
shows an exemplary error message for the
sensor respectively input S2 (lower storage
cylinder temperature).
If the connection to one or several
sensors is damaged, it has to be
checked and be restored if required.
The warning message will disappear once
the malfunction has been eliminated.
In case of an incomplete system
installation, the error messages must be
deactivated individually. To do so, select
the sensor which shall be deactivated in
the menu Messages (in the example on
the right hand side S2).
The submenu Inputs (for the concerned
sensor) will open.
1. Scroll down to sensor check with the
help of the programming stylus.
2. Select the button and set it to No.
3. Conrm the entry.
The function "sensor check" for the
sensor which is not connected is
deactivated now and the a.m. warning
message will disappear.

Setting of system parameters "Regtronic RD-W"
5.2 Modi cation of presettings and control parameters
The system controller "Regtronic RD-W" has
to be programmed in such a way that a supply
of heating water according to requirements to
the dwelling stations "Regudis" is guaranteed
at any time. To achieve this, the controller is
preloaded with parameters for the control
of the heating system covering many
applications.
The system constellation may, however,
call for an adaptation of the controller
programming. This may concern the following
sections of the heating system:
5.2.1 Buffer storage cylinder loading
Supply of the heat required by the buffer
storage cylinder is carried out by the
activation of a heat generator or a loading
pump through the controller. Alternatively,
loading of the buffer storage cylinder can
be carried out by a control integrated in the
heat generator.
This speci cation already has to be
made during installation (see installation
instructions doc. no. 134209380). A
corresponding cabling is required.
Illustr. 21
The main menu for storage cylinder loading can be accessed from the
status page by selecting the heat generator/loading pump icon (see illustr.
20). Alternatively, it can be accessed via the cogwheel symbol and the button
STORAGE CYLINDER LOADING.
