Peripheral functions

The room controllers and room units can be configured as master or slave devices. A
number of rules must be adhered to in this process.
When more than one room unit is used in a master/slave configuration, all such room
units must be of the type with a button for setpoint adjustment. In the case of room units
with a mechanical setpoint adjuster, only one room unit may be connected. (Room
units with mechanical setpoint adjusters and those with pushbuttons for setpoint
adjustment must not be combined.)
The same principle applies to the RXC10.1 room controller, which incorporates a
temperature sensor and mechanical setpoint adjuster.
• Room units with
pushbutton setpoint
adjustment (more than
one of this type allowed)
• Room units with a
mechanical setpoint
adjustment (only one unit
of this type allowed)
Room units with a mechanical setpoint adjuster must NOT be used in configurations
where the room unit is connected via the room controller to a building automation
system and controlled via bus by Setpoint shift for heating / cooling (see page 74).
• Do not use more than one
room unit with a
mechanical setpoint
adjuster
• Do not combine room
units with mechanical
setpoint adjusters and
room units with push-
buttons for setpoint
adjustment.
