12.1 Sensors and measuring instruments
Temperature sensors
The product range includes high-precision platinum temperature sensors, atscrew
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 RESOL SP10.
V40 owmeter
The RESOL V40 is a measuring instrument for detecting the ow of water or water/
glycol mixtures. After a specic volume has passed, the V40 reed switch sends an
impulse to the calorimeter. The heat quantity used is calculated by the calorimeter
using these impulses and the measured temperature difference with the help of
pre-dened parameters (glycol type, concentration, heat capacity, etc.).
12.2 VBus

accessories
SD3 Smart Display / GA3 Large 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-efciency LEDs and lter glass assures a high optical brilliance and good
readability even in poor visibility conditions and from a larger distance. An additional
power supply is not required. One module is required per controller.
The RESOL GA3 is a completely mounted large display module for visualisation
of collector- 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 antireective
lterglass 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.
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.
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 congured 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 monitor-
ing or for diagnostics of faults.
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 lter settings and much more await you.
12.3 Interface adapters
VBus
®
/ USB & VBus
®
/ LAN interface adapters
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 data via the VBus
®
. The RESOL
ServiceCenter software is included.
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 RESOL VBus
®
. The RESOL ServiceCenter software
is included.
