Sensors and measuring instruments
Temperature 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.
For more information see our catalogue and our website.
SP10 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 RESOL SP10.
VFD Grundfos Direct Sensor™
The VFS Grundfos Direct Sensor™ is an digital sensor that measures both temper-
ature and flow rate.

accessories
SD3 Smart Display
The RESOL Smart Display is designed for simple connection to RESOL controllers
with RESOL VBus
®
. It is 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. An addi-
tional power supply is not required.
GA3 Large display module
The GA3 is a completely mounted large display module for visualisation of collec-
tor- and store temperatures as well as the heat quantity yield of the solar system via
one 6-digit and two 4-digit 7-segment-displays. An easy connection to all controllers
with RESOL VBus
®
is possible. The front plate is made of antireflective filterglass and
is printed with a light-resistant UV-lacquering. The universal RESOL VBus
®
allows
the parallel connection of 8 large displays as well as additional VBus
®
modules.
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.
The AM1 Alarm module ensures that occurring failures can be immediately recog-
nised and repaired, even if the system and the controller are difficult to access or
located in a remote place. Thus, the reliability and the stable yield of the system are
ensured.
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. The DL2 can be configured and read-out with a standard Internet browser
via its integrated web interface. 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 RESOL VBus
®
. It can be connected directly to a PC or router for
remote access and thus enables comfortable system monitoring for yield monitoring
or for diagnostics 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 RESOL controllers. Get
a comprehensive 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.
VBus.net
The Internet portal for easy and secure access to your system data.
VBus.net is all about the data of your RESOL controller. Live data of your system,
customized filter settings and much more await you.

Interface adapters
VBus
®
/ USB interface adapter
The VBus
®
/ USB interface adapter is the interface between the controller and a
personal computer. With its standard mini USB port it enables a fast transmission of
system data for processing, visualising and archiving as well as the parametrisation
of the controller via the VBus
®
. The RESOL ServiceCenter software is included.
VBus
®
/ LAN interface adapter
The VBus
®
/ LAN interface adapter is designed for the direct connection of the
controller to a PC or router. It enables easy access to the controller via the local
network of the owner. Thus, controller access, system parameterisation 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 RESOL VBus
®
. The
RESOL ServiceCenter software is included.
