Reference Story

A new shopping centre, StadtGalerie, has boosted the appeal

of the city centre in Witten in the Ruhr region of Germany

since autumn 2009. Vacon, in cooperation with Borken-based

Josef Rehms GmbH, ensures that customers are able to shop

in a comfortable environment throughout both summer and

winter.

A pleasant climate plays an important role in creating an en-

joyable shopping environment. At the StadtGalerie Witten, the

climate is maintained by Josef Rehms GmbH with the help of

Vacon – a partnership with a history of 10 years. As supplier

of the building management equipment, Rehms was respon-

sible for carrying out all the work for the building technical

systems and for installing most of the Vacon AC drives at the

Witten StadtGalerie.

The new Vacon 100 HVAC AC drive, designed for heating, ven-

tilation and air conditioning systems, convinced Josef Rehms

GmbH that it was the right drive for the job. The Vacon 100

HVAC offers an affordable price/performance ratio for the

Witten shopping centre and, above all, is equipped with all the

required accessories, IO and communication interfaces for

installing and operating the HVAC drives.

BACnet onboard!

The main reason why Vacon was chosen for the Witten shop-

ping centre is that the Vacon 100 HVAC is equipped with

BACnet/IP based on Ethernet. No additional equipment is

needed for communication with the controller.

In addition, the drive is very simple to set up with its straight-

forward start-up wizard. This asks for the most important

parameters in the local language, allowing the user to set the

parameters for the unit by pressing just a few buttons, after

which it is ready for operation. Help is available in plain text

in the graphical keypad for parameters, faults and alarms,

which is a great benefi t during commissioning and mainte-

nance.

All the necessary interfaces for the HVAC market are stan-

dard onboard the Vacon 100 HVAC. As well as the BACnet IP,

it also has Modbus TCP based on Ethernet. BACnet MSTP, N2

and Modbus RTU communication interfaces are also avail-

able. In addition to the needed analog, digital and relay inputs/

outputs, there are two other slots, giving extra fl exibility.

The Vacon 100 HVAC is designed specifi cally for the HVAC

market thanks to its various built-in HVAC functions. It has

two programmable PID controllers that can be used for ac-

curate HVAC process control or even to control the process

through external motors. The real-time clock with built-in

calendar functions and sleep mode helps optimize the HVAC

process and provides great potential for energy savings. The

skip frequencies and multi-pump features ensure that the

HVAC fan or pump will have a long life.

The Vacon 100 HVAC series is available in the power range up

to 160 kW. Drives with 220 V, 400 V and 480 V supply voltages

are available.

Facility manager controls each AC drive separately

via Ethernet

With an integrated Ethernet onboard, each Vacon 100 HVAC

drive has its own IP address. The user can set the param-

eters, control the drive and monitor the HVAC process sig-

nals graphically using a computer installed with Vacon Live

software. Vacon Live can communicate with the Vacon 100

HVAC drives via Ethernet or RS485/USB and can be used for

commissioning the drive and the HVAC process and for main-

tenance and diagnostics.

In normal operation, the drives are controlled through Sie-

mens PX DDC substations. The facility manager can log into

the drive through the Vacon Live software for monitoring,

analysis and diagnostics without disturbing the operation of

the drive.

Tried and tested down to the smallest detail

Jörg Drunkenmölle, Sales Engineer at Vacon GmbH, Vacon’s

subsidiary based in Essen, Germany, is extremely pleased

with how the project has gone: “In the StadtGalerie in Witten,

we were able to use nearly all the features of the Vacon 100

HVAC for the very fi rst time. This has been a showcase for the

unit, demonstrating its power and capabilities, which has put

the company in a good light as well.”

One of the features mentioned by Mr Drunkenmölle is the

fi re mode, which has been developed to assist in emergen-

cies and help save lives in case of a fi re hazard. “For example,

when a smoke detector sends an alarm, this activates the fi re

mode and the drive runs at a pre-defi ned speed to remove

smoke from the building, ignoring faults and warnings, so

that people can leave the building safely,” explains Mr Drunk-

enmölle.

Bernhard Lukas, head of measuring and control systems and

electrics at Josef Rehms GmbH, also gives a satisfi ed report

for the project: “Thanks to the use of BACnet technology in

the Vacon AC drives, we were able to achieve much greater

savings in this project than had been possible with conven-

tional solutions.”

For the customers in the Witten shopping centre, this suc-

cessful partnership means one thing above all: a relaxed,

safe shopping experience in a pleasant climate.

In partnership with Josef Rehms GmbH, Vacon provides a pleasant climate in the Witten shopping centre. With its sales area of 11,500 square metres and around 1,000 square metres of restaurants, on three fl oors, with two clothing stores and a two-storey parking facility on top, the StadtGalerie has been boosting the appeal of Witten city centre since autumn 2009.

In the Witten shopping centre, the operator can control the AC drives and perform diagnostics via Siemens PX DDC substations or can access individual units via the Ethernet.

The Vacon 100 HVAC has an integrated BACnet system, so there are no additional communication costs. Since each of the AC drives in the Witten StadtGalerie can be controlled separately, this sharply reduces the amount of energy needed to operate the shopping centre.
