Application

The 0-10 V VR 34 interface is used to connect
BEMS equipment to a Vaillant boiler with an
eBus interface. It transfers a voltage input on
terminal "I" into a temperature setpoint for
the boiler. Terminal "F" can be used to signal
a boiler fault (24 V). This signal will remain
until the fault is corrected and the boiler has
been reset. Use terminal "F" and "24 V" to
connect a 24 V relay with a maximum current
of 30 mA.
