11.1 Sensors and measuring instruments
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 RESOL SP10 Overvoltage protec-
tion.
VFS and RPS Grundfos Direct Sensors™
The RPS Grundfos Direct Sensor™ is an analogue sensor that measures both tem-
perature and pressure. The VFS Grundfos Direct Sensor™ is an analogue sensor
that measures both temperature and flow rate.
V40 flowmeter
The RESOL V40 is a measuring instrument for detecting the flow of water or wa-
ter/glycol mixtures. After a specific volume has passed, the V40 reed switch sends
an impulse to the calorimeter. The heat quantity used is calculated by the calorime-
ter using these impulses and the measured temperature difference with the help of
pre-defined parameters (glycol type, concentration, heat capacity, etc.).
11.2 VBus
®
accessories
SD3 Smart Display / GA3 Large Display
The RESOL SD3 Smart Display is designed for simple connection to RESOL con-
trollers via the 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 bril-
liance. An additional power supply is not required. One module is required per
controller.
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 con-
trollers with a 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.
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.
KM2 Communication module
The KM2 Communication module is the ideal interface between a solar or heating
controller and the Internet. Due to the easy and secure connection to the VBus.net
Internet portal, system data can be visualised and for example reports on system
status via e-mail made available. With the RESOL RPT Parameterisation Tool the
controller can be parameterised over the Internet.
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.
11.3 Interface adapters
RESOL 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 transmis-
sion 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
controller to a PC or router. It enables easy access to the controller via the local
network of the owner. Controller access and data charting can be effected from
every workstation of the network by means of the RESOL ServiceCenter Soft-
ware. The VBus
®
/ LAN interface adapter is suitable for all controllers equipped
with a RESOL VBus
®
. The RESOL ServiceCenter software is included.
