5InRoom Controller - Operating Instructions

The InRoom Controller offers maximum possible ope-

rating safety for industrial applications and a versatile

operator interface. There are two interfaces with one

controller.

The InRoom Controller works by having each cooling

unit possess its own controller while all controllers can

be linked together in a bus system.

This way a natural redundancy is obtained that causes

the system to function with the least expense.

The second interface can be accessed using a com

puter. Using the screen of a Laptop or PC provides the

best way of visualizing parameter settings. This is the

most comfortable way of doing a component-related

conﬁguration.

Beyond the basic air conditioning functions, the control

system provides some interesting features like an intel-

ligent management of high/low pressure-alarms, a pro-

portional fan speed control which opens a wide spectrum

of applications and time-based functions like:

- week timer

- unit sequencing within deﬁnable unit groups

The heart of the control system is the I/O controller on

which up to 4 EAIO/EDIO boards for additional in- and

outputs can be installed. The exploitation of the third

dimension provides maximum accessibility and an easy

board exchange in case of modiﬁcations.

The control systems manages four busses:

1. IIC-bus for the communication between the I/O

controller and the EAIO/EDIO boards.

2. RS485 IO-bus for the communication among the

cooling units.

3. RS485 BMS-bus for the communication with a

building management system.

4. RS485 Aux-bus for the communication with optio

nal components capable of bus connection.

For service purposes like software download and control

by a remote computer a RS232 interface is located on

the I/O controller in the same way as on the InRoom

Controller interface.
