Sensors
The product range includes high-precision platinum temperature sensors, flatscrew
sensors, outdoor temperature sensors, indoor temperature sensors, cylindrical
clip-on sensors, also as complete sensors with immersion sleeve.
Overvoltage protection device
In order to avoid overvoltage damage at collector sensors (e. g. caused by local
lightning storms), we recommend installing the overvoltage protection SP10.

accessories
SD3 Smart Display / GA3 Large Display
The remote displays are used for visualising data issued by the controller: collector
temperature, store temperature and energy yield of the solar thermal system. The
use of high-efficiency LEDs and filter glass assures a high optical brilliance and
good readability even in poor visibility conditions and from a larger distance. Both
remote displays are connected to the controller by means of the VBus
®
.
AM1 Alarm module
The AM1 Alarm module is designed to signal system failures. It is to be connected
to the VBus
®
of the controller and issues an optical signal via the red LED if a failure
has occurred. The AM1 also has a relay output, which can e. g. be connected to a
building management system (BMS). Thus, a collective error message can be issued
in the case of a system failure.
VBus
®
/ LAN interface adapter
The VBus
®
/ LAN interface adapter is designed for the direct connection of the con-
troller to a PC or router. It enables easy access to the controller via the local net-
work of the owner. Thus, controller access and data charting can be effected from
every workstation of the network. The VBus
®
/ LAN interface adapter is suitable
for all controllers equipped with a VBus
®
. The ServiceCenter software is included.
DL2 Datalogger
This additional module enables the acquisition and storage of large amounts of
data (such as measuring and balance values of the solar system) over a long period
of time. System access is possible with just a few clicks via the VBus.net Internet
portal. For transmission of the data stored in the internal memory of the DL2 to a
PC, an SD card can be used. The DL2 is appropriate for all controllers with VBus
®
.
The datalogger can be connected directly to a PC or router for remote enquiry
and thus enables comfortable system monitoring for yield monitoring or for diag-
nostics of faults.
DL3 Datalogger
Be it solar thermal, heating or DHW heat exchange controllers – with the DL3
you can easily and conveniently log system data of up to 6 controllers. Get a com-
prehensive overview of all controllers connected with the large full graphic display.
Transfer data with an SD memory card, or use the LAN interface to view and
process data on your PC.
KM1 Communication module
The KM1 Communication module is the network connection for solar and heating
systems, especially suited for technicians managing large systems, heating installers
and home owners who like to keep a close eye on their system. VBus.net enables
e. g. controlling the system yield in a comprehensive system scheme image.
RCTT Remote control
The RCTT Remote control enables rapid heat-up activation via the button without
having to access the controller menu (see page 33).
VBus.net
The Internet portal for easy and secure access to your system data.
VBus.net is all about the data of your controller. Live data of your system, custom-
ized filter settings and much more await you.
