2.3 Calibrating the room sensor

If the temperature displayed on the room controller (current temperature on the bottom right of
the display) does not match the actual room temperature, the measured temperature of the
room sensor can be changed and reset. On calibration, the currently displayed sensor temper
ature needs to be changed to match the directlymeasured roomtemperature (referencetemper
ature).

4 Communication

Communication

The serialsystem bus interface RS-485 enables the TROVIS 5572 Room Controller tocommuni
cate with a control system (GLT). A complete control system can be implemented using a suit
able software to visualize the process and to enable communication.

The operation of the controller requires a constant bus link (data cable).The bus line is designed
in an open ring structure to connect individual control equipment. The data cable is connected
at the end of the bus lineto thecontrol station over a RS-485/RS-232 converter (e.g.CoRe 01).

The bus connection range (cable length) is maximum 1200 m. A maximum of 128 devices can
be connected in such a segment. Repeaters must be used (for example, CoRe 01) to regenerate
the signal level over long distances or when more than 32 devices are connected to one bus
line. A maximum of 246 devices can be addressed and connected to a bus with 8-bit
addressing.

Caution!

You are required to follow the relevant standards and regulations applicable to light­ning and overvoltage protection on installing the controller.

A transmitting and/or receiving test can be initiated in the

Note!

The room controller must be mounted at a height of 1.50 m.
Make sure that the operation of the room controller is not affected by heat sources (radiators,
lights, electrical appliances) or by drafts close to doors or windows.
The room controller should not be covered by curtains or any pieces of furniture.

To mount and wire the room controller, remove the housing from the base.

How to proceed:

1. Press down the tongue on the bottom of the controller and tip the housing section for­ward to remove it from the base.

2. Screw the base to the wall.
