inVENTer Connect controller platform | Installation instructions
SYSTEM OVERVIEW
1.1 Sensor technology
Different sensors are available in the inVENTer Connect controller platform. These are required
to monitor the relevant parameters in the various ventilation zones and to ensure automated
ventilation control according to the set profiles. Demand-controlled ventilation is enabled in the
ventilation zone assigned to the sensor on the basis of the respective reference variable.
The CO
2
sensor also has a humidity/temperature sensor.
For initial commissioning (see operating instructions for Connect controller platform: Commission-
ing) and to integrate the sensor system into the ventilation system, a button and an associated
LED are used in each case.
The following displays are possible and uniform for all devices to be paired:
LED colour

The data transmission between the sensors and controller takes place at fixed intervals. Depend
-
ing on the sensor, the value determination is defined as a fixed cycle or as a check cycle:
• Fixed cycle (60 minutes):
Here the sensor system sends a signal to the controller together with the sensor value
(temperature, humidity, CO
2
content), thereby reporting its status.
• Check cycle:
Here the sensor values are read periodically and checked whether they correspond to the
specified value or are within the tolerance range for this value.
If there are any deviations, the newly measured data is transmitted to the controller.
Sensor hierarchy
TIP:
Several sensors that perform the same task in a zone can be paired with the controller.
The controller then arranges these according to the following sensor hierarchy:
