Functions
Control of a Vaillant geoTHERM/3 VWS220/3
– 460/3 heat pump via Modbus TCP/IP.
Additional control of up to three Vaillant VR60 mixer modules and up to six Vaillant VR90 re-
mote control units.
Together with the ise eBUS Adapter, the ise smart connect Modbus Vaillant establishes the
connection between the Vaillant geoTHERM/3 heat pump and your building management sys-
tem (BMS) via Modbus TCP/IP.
Important note:
To ensure functional control, the use of the both system components is required. The ise smart
connect Modbus Vaillant can therefore only be used together with the ise eBUS Adapter.
The system components can be ordered as a set or individually (for replacement purposes).
A Vaillant geoTHERM VWS220/3
– 460/3 heat pump is necessary in the installation. No other
heat pump is compatible.
Important!
The device must be supplied with voltage by a dedicated power supply unit. Do not use the aux-
iliary voltage output of a KNX power supply unit which is also supplying a KNX line.

Definitions and explanation of terms
ise eBUS Adapter
The ise eBUS Adapter is a system component to connect the Vaillant bus modular control with
the Modbus system. It connects:
- devices of the ise smart connect series for eBUS connection (in this case, ise smart connect
Modbus Vaillant) and
- the Vaillant system together
over a USB interface.
It is a specially designed system component for this use case.
Any other or extended use is considered improper.
Vaillant system
All components of the Vaillant heating system are described as the Vaillant system. One of
these components must be a geoTHERM VWS220/3
– 460/3 heat pump, which will be re-
ferred to as geoTHERM/3 from now on. Additionally, the heating system can contain up to
three VR60 mixer modules and up to six VR90 remote control units:
Information on the operation, installation and any required accessories can be found in the
corresponding documents issued by Vaillant.
eBUS
The commands sent via Modbus TCP/IP are prepared via the ise smart connect Modbus Vail-
lant and the ise eBUS Adapter to enable communication with the Vaillant system via the eBUS.
Separate addressing of ise system components for the eBUS is not necessary.
The eBUS connection point is described in chapter 2.5
“Connection of the ise eBUS Adapter
.
The relevant instructions for the installation on the eBUS provided by Vaillant (connec-
tion, procedures, cable selection, etc.) must be observed.
