Connect room units in master/slave configurations

The room controllers or room units can be configured as master or slave. A number
of rules must be adhered to in this process.
If more than one room unit is used in a master/slave configuration, only room units
may be used with a button for setpoint shift. In the case of room units with a
mechanical setpoint shift, only one room unit may be connected (combining room
units with mechanical setpoint shift and room units with buttons for setpoint shift is
not allowed).
Applies as well for RXB10 room controllers in room unit housings.
• Room unit with button
setpoint shift (several
room units allowed).
• Room unit with
mechanical setpoint
shift (only one room unit
allowed).
If the room unit is connected to the building automation and control system via
room controller and is controlled via the bus with Setpoint shift heating/cooling, a
room unit with mechanical setpoint shift CANNOT be used.
• Use of more than one
room unit with a
mechanical setpoint
shift.
• Combination of room
units with mechanical
setpoint shift and room
units with buttons for
setpoint shift.
