Safety notes "Regtronic RD-W"

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.

Construction and function "Regtronic RD-W"

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.

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 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).

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.
