Specific functions for heating plants Heat request The central apartment unit generates heat demand signals based on the collected heat requests and forwards the signals to the controller for heat generation. The heat demand signals can be delivered via the universal relay output (switching) or the DC 0…10 V output (modulating) of an RRV912 heating circuit controller or RRV934 multi-controller. Flow temperature control / limitation The flow temperature is controlled via the RRV934 multi-controller.
PAGE 5
Outside temperaturedependent night setback The Economy room temperature setpoint is increased as a function of the composite outside temperature. Changeover is adjustable and helps prevent load peaks when changing from Economy to Precomfort or Comfort for instance. Minimum flow temperature setpoint The minimum flow temperature setpoint is raised as a function of the composite outside temperature, thus ensuring a minimum flow temperature for uncontrolled rooms.
PAGE 6
Specific functions for monitoring and operation Door and window contacts The central apartment unit monitors the connected door and window contacts. A monitoring delay time can be parameterized for the door / window contacts and, in addition, a message delay time for the door contacts. The opening of a monitored door / window contact can be used for triggering a switching group (event-driven) and for generating an alarm message.
PAGE 7
Scenes The different blind positions (fully raised or fully lowered) and different light settings (on, off, dimming state) can be saved as scenes and retrieved later. In addition to manual retrieval, the scenes can also be called up via the internal time switch (time switch can "Always“ be processed or "Only if absent“), presence simulation or events (e.g. twilight, absence).
PAGE 8
System-internal faults can be transmitted to external components via the fault outputs. Communication The central apartment unit is capable of communicating via a wireless bus (KNX RF) or a wired bus (KNX TP1). Service interface The OCI700 service tool can be connected to the service interface (RJ45) located on the underside of the central apartment unit.
PAGE 9
When power is restored, the central apartment unit and its components will resume normal control operation. Error messages To facilitate fault tracing, the QAX910 delivers detailed error messages. They are output as clear-text messages, thus simplifying the interpretation of messages by the user or the heating engineer. Error messages can be used for triggering other events, such as optical or audible alarms. The last 10 error messages are saved as a history and can be individually retrieved.
