257204A Datalogger with BACnet IP 1 2.0 1,800.00
The DL2 datalogger enables the acquisition and storage of large amounts
of data such as energy heat metering and recorded values of the solar
system over a long period of time when connected to an iSolar™ series
controller. The datalogger, when connected to a network through the
integrated Ethernet socket, can be confi gured and viewed with any standard
internet browser via its integrated web interface, without additional software.
Download data through the web interface or an SD memory card for further
data processing in spreadsheet programs.

DL3
The DL3 datalogger / BACnet/IP gateway provides communication
translation between iSolar™ controllers and DDC system which are capable
of BACnet/IP communications. Conforms with BACnet PICS, Up to six
iSolar controllers can be connected to DL3 with two conductor wire (bell
wire) at least 20 AWG up to a distance of 150 feet. The DL3 has three
additional inputs for Pt1000 temperature sensors and one 4—20 mA Current
Loop analog input. A confi gurable IP address and password protection
allows for access from any PC with an internet connection. Download data
through the web interface, an SD memory card or USB cable for further data
processing in spreadsheet programs.

VBus.net is a service portal that offers access to solar thermal system data
from all over the world. No DSL router confi guration is required. To use VBus.
net service, the system must be equipped with a Caleffi iSolar™DL2 or DL3
Data Logger. After signing on at www.VBus.net, the Data Logger can be
registered with the system. VBus.net enables users to access their solar
thermal system data from all over the world, just by using a regular web
browser. No additional software or app is required, only a registered account
for the VBus.net service, a web browser and internet connection. Many
mobile devices are supported as well.

Multiple WMZ or WMZ-G1 energy heat meters can be cascaded
together on the VBus connection. One WMZ is configured as the
master and additional WMZ meters are confi gured as slaves. Up to 16
meters can be cascaded together with two conductor wire (bell wire)
at least 20AWG and up to 150 feet for transmission of data values to
aconnected PC, DL2 or DL3 Datalogger.
The connection sequence is arbitrary, up to 16 can be cascadedtogether.
