Special features of setpoint readjustment

As can be seen from the "Display values" table, the setpoints for Economy,
Precomfort and Comfort can also be directly overwritten.
If, in the relevant room group, configuration parameter "Setpoint priority RMB
central control unit is set to "Yes", the setpoints are supplied by the room group and
the individually adjusted values will be overwritten again.
If, on one of the RXB/RXL room controllers, the "Slave" function is selected, the
setpoints can only be preselected conditionally, because they are coupled with the
master's setpoints.
This means that only the master room controller acquires the room temperature. It
sets the operating mode and setpoints for room temperature.
For more detailed information, refer to the description of the master-slave behavior
in the Technical Handbook of the RXB/RXL room controller (CA2A3899en).
