Connecting external sensors
The operating mode
Automatic sensor
of the automatic mode is controlled by an analogue sensor signal that is
generated by one or several sensors. To establish the connection between the sensor module and Master Controller
terminal X2, use the type of cable stipulated for transmitting the sensor signal. The cable is inserted into the FOCUS
through one of the pre-cut cable guides.

Connecting the status relay
A status relay on the Master Controller signals the operating status of the fans (factory setting).
Fan off: contacts open
Fan on: contacts closed

Connecting external release
The operation of the system can be activated or deactivated by an external release signal. The potential-free release
contacts are located next to the terminal X1 and are bridged ex-factory.

Connecting digital inputs and outputs
The digital inputs and outputs DIO1 and DIO2 can only be programmed with the configuration software. At the
factory, the following parameters are specified:
DIO1: Activate automatic (as a digital input signal)
DIO2: General message (as a digital output signal)
