A V40 owmeter can be connected to the terminals V40 and GND (either polarity).
The terminals marked PWM are control outputs for a high-efciency pump (see
page 18).

2.3 Data communication / Bus
The controller is equipped with the RESOL VBus
®
for data transfer and energy
supply to external modules. The connection is to be carried out at the two termi-
nals marked VBus (any polarity).
One or more RESOL VBus
®
modules can be connected via this data bus, such as:
• RESOL DL2 Datalogger
• RESOL DL3 Datalogger
Furthermore, the controller can be connected to a PC or integrated into a network
via the RESOL VBus
®
/USB or VBus
®
/LAN interface adapter (not included). Different
solutions for visualisation and remote parameterisation are available on the RESOL
website www.resol.com.
