Siemens Central apartment unit with consumption data acquisition QAX913 CE1N2740en
Building Technologies 2016-01-30
The individual wireless components are connected to the central apartment unit by
selecting the room / switching group / function to be assigned to the new wireless
components and then pressing the connect or function button for the correspond-
ing components.
When connecting devices from the Hager tebis RF range, the TX100 configurator
is required (supplied by Hager).
To check the connections made, a list with all devices can be displayed for each
room. In addition, device lists with smoke detectors, meteo sensors, switching
group relays and fault inputs and outputs are available.
Using the binding or multifunction buttons, a connection test can be triggered on
the individual devices. The central apartment unit indicates error-free connections
both optically and audibly.
The connected RF devices are monitored on a regular basis. An error message is
displayed on the central apartment unit when no signal is found.
Control is no longer guaranteed if radio communications between the central apart-
ment unit and the system components to be controlled are interrupted. If communi-
cation breaks down, the position of the actuators connected to an RRV934 multi-
controller is maintained and can only be changed manually. The heating circuit
valves on RRV912 and RRV918 will open. By making use of the built-in room
temperature sensor, the SSA955 radiator control valves continue to provide
control, maintaining a room temperature setpoint of 21 °C.
Ventilation plants continue to operate at the present ventilation state for about
30 minutes and then shut down.
System components resume normal control operation as soon as radio communi-
cations are reestablished.
Control is no longer secure in the event of a power failure to the central apartment
unit.
If communication breaks down, the position of the actuators connected to an
RRV934 multi -controller is maintained and can only be changed manually. The
heating circuit valves on RRV912 and RRV918 will open. By making use of the
built-in room temperature sensor, the SSA955 radiator control valves continue to
provide control, maintaining a room temperature setpoint of 21 °C.
Ventilation plants continue to operate on the present ventilation state for about
30 minutes and then shut down. The air conditioner can be operated using the
unit's own remote control.
The central apartment unit and its components resume normal control operation as
soon as power returns.
The QAX913 delivers detailed error messages to simplify localizing any errors.
They are output as clear-text messages, thus simplifying the interpretation of mes-
sages 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 in history and can be individually retrieved.
The central apartment unit can be reset to the supply state via an operating line.
