Safety notes "Regtronic RD-W"
2. Safety notes
2.1 Correct use 2.2 Denition 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-specic 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 dene 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 qualied
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 modication 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!
1 If differential pressure control is carried
out by the riser pump (3), a differential
pressure sensor (5) is not required.

Construction and function "Regtronic RD-W"
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 signicantly 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).

4. Operation fundamentals
The display of the controller has two basic
functions:
• Retrieval of system-speci c
information, especially regarding
temperatures and pressure
conditions.
• Entry of system-speci c parameters
for the control of storage cylinder
loading and of the heating
temperature in the supply pipe of
the riser supplying the connected
"Regudis" dwelling stations.
