Equipment properties
Application
The VRT 392f is a programmable room temperature
controller for the heating system. The VRT 392f also
controls the hot water generation.
You can use the VRT 392f to specify various room target
temperatures (programming) — for different times of the
day and for different days of the week.
In automatic mode, the VRT 392f controls your heating
in accordance with this input (see Fig. 0.1).
You can also use the VRT 392f to define daily heat-up
times for hot water generation.
Fig. 0.1 Automatic heating operation: Example of setting the
room target temperature for different times of the day
In addition, the VRT 392f can be used to control the
following accessory components:
– Circulation pump for water heating in combination
with a VR 40 multi-functional module
– Conventional hot water cylinder
– Vaillant layer type storage tank actoSTOR
The VRT 392f can be part of a new heating and hot
water system or it can be incorporated into
existing heating systems. The appliance must have an
eBUS interface.
eBUS is a standard communication method used for
the exchange of data between heating technology
components.
Product specifications
– eBUS interface
– Wireless communication with a Vaillant appliance
– Illuminated graphical display (display field)
– Operation via both dials in accordance with the
principle "Turn and Click"
– The radio receiver unit can be mounted directly on the
operating panel of the appliance or separately on the
wall
- The controller can be mounted separately on the wall
– Equipped for operation with the Vaillant diagnosis
software vrDIALOG 810/2 and the Vaillant Internet
Communication System vrnetDIALOG, i.e. remote
diagnosis and remote adjustment

1.4 CE label
The CE label confirms that the Vaillant Room
Temperature Controller VRT 392f fulfils the
fundamental requirements of the following relevant
directives.
2 Safety
The VRT 392f may only be installed by a certified expert
technician. This person is also responsible for the proper
installation and initial operation.
H
Caution!
Risk of being scalded by hot water!
When the target temperature is
abo
ve 60 °C, there is a risk of scalding at the
hot water taps. Small children and elderly
people can be at danger even at lower
temperatures.
Risk to persons should be excluded through the
selection of an appropriate target temperature
(see Section 4.7.4).
Caution!
Risk
of being scalded by hot water!
If your expert technician has activated the
anti-legionella function for the hot water
cylinder, the temperature of the hot water at
the draw-off points may exceed 60 °C at
specific times.
Find out from your expert technician whether
the anti-legionella function has been activated
and if so, on what day and at what time.

3.1 Intended use
The VRT 392f is a state-of-the-art device which has
been constructed in accordance with the standard safety
regulations.
However, in the event of improper use or use not as
intended, impairment of the equipment and other items
can arise.
The VRT 392f serves the room temperature and timedependent control of a heating installation with or

information can be obtained from the default display:
– the type of operation (automatic, manual or off) of the
heating circuit
– the current room temperature
The default display is described in detail in Section 4.3.3.
The functions of both dials are described in Section 4.3.
h
Note
The display is normally switched off to save
power. This increases the service life of the
batteries.
T
he display and lighting are activated as soon
as you turn or click one of the dials. If the
appliance is not used for more than one minute
the basic display returns and switches off after
approx. 10 minutes.
Note
W
hen the dial is turned the values to be
displayed must first be called up by the radio
receiver unit. Until these values are obtained
only dashes instead of values will be displayed
(--). This generally takes up to two seconds.
Depending
on the ambient conditions, it may
take up to 15 minutes until the current data are
called up by the radio receiver unit and are
subsequently displayed.
If
dashes (--) are displayed continuously,
consult your expert technician.

t
o the Vaillant "Turn and Click" principle.
When turning (forwards or backwards) the adjusters
locate in the next position with a detectable click. Each
index step also moves the cursor one position forwards
or backwards in the display.
By clicking (pressing) you can highlight or accept
changes to a parameter.
