Input variables
The data that the device usesin its control algorithms and /or to be displayed may come from:
• the internal sensors;
• the KNX bus through standard Communication Objects.
The processed data can also be transmitted on the KNX bus as Communication Objects. The classification of
the input variables is shown in Table 2.

Table 2 - Input variables from internal sensors, physical inputs and standard communication objects
The device does not have outputs for direct switching or control of heating
/
cooling terminals or for status or
values signalling. The output variables include exclusively communication objects that are sent on the bus,
received and processed by KNX actuators (general-purpose or dedicated to HVAC applications).
