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.

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

1.4CE label
The CE label confirms that the Vaillant Room Temperature Controller VRT 392f fulfils the fundamental requirements of the following relevant directives.
2Safety
The VRT 392f may only be installed by a certified expert technician. This person is also responsible for the proper installation and initial operation.
HCaution!Risk of being scalded by hot water!
When the target temperature is
above 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 Instructions for operation
3Instructions for operation
3.1Intended 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 without hot water generation/circulation pump in conjunction with a Vaillant appliance and an eBUS interface.
Operation with the following accessories is permissible:
–Circulation pump for water heating in combination with a VR 40 multi-functional module
–Conventional hot water cylinder
–Vaillant layer type storage tank actoSTOR
Any other use or extended use is considered to be use other than intended. The manufacturer or supplier is not liable for any resulting damage. The owner alone bears any risk.
Intended use also includes observance of the Operating and Installation Manual as well as all other applicable documents.
3.2Ambient conditions
The controller and radio receiver unit may only be installed in dry rooms.
Please make sure:
–that the air in the room can circulate freely around the VRT 392f and the VRT 392f is not covered by furniture, curtains or other objects.
–that all the radiators in the room where the VRT 392f is fitted are fully on.
3.3Care
Clean the casing of the VRT 392f with a damp cloth. Do not use abrasive materials or cleaning agents that could damage the operator control elements, parts of the casing or display.
3.4Manufacturer's guarantee

3 Operating element of the left-hand dial
Fig. 4.1 shows the default display. The following 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.
hNoteThe display is normally switched off to save power. This increases the service life of the batteries.
The 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
When 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.

4.3Operating concept
The operator input in the default display is described in Section 4.3.3.
The operating concept described below applies to the basic display (Fig. 4.2) and to the various different display/input screens of the user level.
The two dials (Fig. 4.1 Items 2 and 3) function according to 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.

Example: Change the room set target temperature of the heating circuit (HC1)
Initial condition: You are in the basic display
(see Fig. 4.2). A description of how to navigate to the basic display is provided in Section 4.3.3.
Turn the dial on the right until the cursor 
appears in front of the target value (room target temperature) of the heating circuit (HC1).
Click the right-hand dial.
The input field for the target value is inversely displayed.
Turn the right-hand dial.
The value for the room temperature changes by 0.5 °C for each index turn of the dial.
Click the right-hand dial once the
required value for the room target temperature has been reached.

Operation 4
The new value is applied. The display changes from inverse back to normal.
This new value applies to the control for a specific period, depending on the operating mode selected; also see Section 4.4.
4.3.3Operation in the default display
In the simplified basic display (Fig. 4.8) in the central area the operating mode for the heating circuit and the internal temperature are displayed.
The default display also provides you with the option of changing the two most important parameters of your heating system quickly and comfortably:
-By turning the left-hand dial you change the operating mode (automatic, manual, off).
-By turning the right-hand dial you can change between the actual room temperature and the set room temperature.
