Peripheral functions
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).
• 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 (page 72), 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.
