▶ Protect the device from moisture, dirt and damage during transport, storage and operation.
▶ Operate the device only in a closed housing (distribution board).
▶ Operate the device only within the specified technical data.
▶ Mounting, installation, commissioning and maintenance must be carried out only by qualified
electricians.
▶ Disconnect device from the supply of electrical power before mounting.
2.2 Qualification of the specialist personnel
Programming the device requires detailed specialist knowledge – particularly about the ETS commis-
sioning software – through KNX training courses.
2.3 Proper use
The Valve Drive Controllers VC/S are intended to be used to activate floor heaters, radiators or cooling
ceilings in a KNX environment.

ABB i-bus® KNX PRODUCT OVERVIEW
3 Product overview
3.1 Device description
The devices are modular installation devices (MDRC) in the pro M design. They are designed for installa-
tion in electrical distribution boards and small housings with a 35mm mounting rail (to EN60715).
The devices are KNX-certified and can be used as products in a KNX system → EU declaration of con-
formity.
The devices are powered via the bus (ABB i-bus® KNX) and require no additional auxiliary voltage supply.
The connection to the bus is made via a bus connection terminal on the front of the housing. The loads
are connected to the outputs using screw terminals → terminal designation on the housing.
The software application Engineering Tool Software (ETS) is used for physical address assignment and
parameterization.
3.1.1 Membrane keypad
Depending on the product variant, the devices can be operated manually using the membrane keypad.
