1 Safety
1.1 Intended use
In the event of inappropriate or
improper use, damage to the
product and other property may
arise.
The product is intended for us-
ing an eBUS interface to control
a heating installation with heat
generators from the same man-
ufacturer.
The room temperature control
controls based on the installed
system:
–Heating
–Domestic hot water genera-
tion
–Circulation
Intended use includes the fol-
lowing:
–observance of accompanying
operating, installation and
maintenance instructions for
the product and any other
system components
–installing and setting up the
product in accordance with
the product and system ap-
proval
–compliance with all inspection
and maintenance conditions
listed in the instructions.
Intended use also covers in-
stallation in accordance with the
IP code.
This product can be used by
children aged from 8 years
and above and persons with
reduced physical, sensory or
mental capabilities or lack of
experience and knowledge if
they have been given supervi-
sion or instruction concerning
use of the product in a safe way
and understand the hazards in-
volved. Children must not play
with the product. Cleaning and
user maintenance work must
not be carried out by children
unless they are supervised.
Any other use that is not spe-
cified in these instructions, or
use beyond that specified in this
document, shall be considered
improper use. Any direct com-
mercial or industrial use is also
deemed to be improper.
Caution.
Improper use of any kind is
prohibited.
1.2 General safety
information
1.2.1 Risk
caused by inadequate
qualifications
The following work must only
be carried out by competent
persons who are sufficiently
qualified to do so:
–Set-up
–Dismantling

0020323630_00 Operating and installation instructions 5
–Installation
–Start-up
–Decommissioning
–Troubleshooting and fault
elimination
▶Proceed in accordance with
current technology.
Work and functions that must
only be carried out or set by the
competent person are marked
by the symbol.
1.2.2 Danger caused by
improper operation
Improper operation may present
a danger to you and others, and
cause material damage.
▶Carefully read the enclosed
instructions and all other ap-
plicable documents, particu-
larly the "Safety" section and
the warnings.
▶As the end user, you should
only carry out those activities
for which these instructions
provide instructions and that
are not marked with the
symbol.
1.3 -- Safety/regulations
1.3.1 Risk of material damage
caused by frost
▶Do not install the product in
rooms prone to frost.
1.3.2 Regulations (directives,
laws, standards)
▶Observe the national regula-
tions, standards, directives,
ordinances and laws.

2 Product description
2.1 Which nomenclature is used?
–System control: Instead of VRT 380/2
–Remote control: Instead of VR 92 and
VR 92/2
2.2 What is the effect of the frost
protection function?
The frost protection function protects the
heating installation and flat from frost dam-
age.
At outdoor temperatures
–Below 4 °C for longer than four hours,
the system control switches the heat
generator on and regulates the target
room temperature to at least 5 °C.
–Above 4 °C, the system control does
not switch the heat generator on, but it
monitors the outdoor temperature.
2.3 What do the following
temperatures mean?
Desired temp. is the temperature to which
you want to heat up the living rooms.
Set-back temp. is the level below which
the temperature in the living rooms does
not fall when outside of the time periods.
Flow temp. is the temperature at which
the heating water leaves the heat gener-
ator.
2.4 What is a zone?
A building can be divided into multiple
areas, which are known as zones. A dif-
ferent requirement can be placed on the
heating installation in each zone.
Examples for dividing into zones:
–Underfloor heating (zone 1) and a ra-
diator system (zone 2) are available in
one building.
–A building is made up of several self-
contained residential units. Each resid-
ential unit has its own zone.
2.5 What is the circulation?
An additional water pipe is connected to
the domestic hot water pipe and forms a
circuit with the domestic hot water cylin-
der. A circulation pump facilitates the con-
tinuous circulation of domestic hot water
through the pipework system which means
that hot water is immediately available,
even at more distant draw-off points.
2.6 What is meant by "time
period"?
Example of heating mode in the mode:
Time-controlled
24 °C
18:0016:30 22:30
16 °C
21 °C

A Time
B Temperature
1 Desired temper-
ature
2 Set-back tem-
perature
3 Time period 2
4 Outside of the
time periods
5 Time period 1
You can divide a day up into several time
periods (3) and (5). Each time period can
comprise an individual start time and end
time. The time periods must not overlap.
You can assign a different desired temper-
ature (1) to each time period.
Example:
16:30 to 18:00; 21 °C
20:00 to 22:30; 24 °C
The system control regulates the living
rooms to the desired temperature within
the time periods. In the times outside of
the time periods (4), the system control

0020323630_00 Operating and installation instructions 7
regulates the living rooms to the lower set-
back temperature (2) that is set.
2.7 Preventing malfunctions
▶Do not cover the system control with
furniture, curtains or other objects.
▶If the system control is installed in the
living room, open all of the thermostatic
radiator valves in this room fully.

If the heat curve 0.4 is selected and 21 °C
is specified for the target room temperat-

shown in the figure. The heat curve is dis-
placed according to the value of the tar-
get room temperature along axis a which
is angled at 45°. At an outdoor temperat-
ure of -15 °C, the control system provides
a flow temperature of 45 °C.
