System-internal faults can be transmitted to external components via the fault out-
puts.
The central apartment unit is capable of communicating via a wireless bus (KNX
RF) or a wired bus (KNX TP1).
The OCI700 service tool can be connected to the service interface (RJ45) located
on the underside of the central apartment unit.
The individual RF components are connected to the central apartment unit by se-
lecting the room / switching group / function to which the new component shall be
assigned and then pressing the binding or function button on the respective system
component.
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 the smoke detectors, meteo sensors, switching
group relays and fault inputs and outputs are available.
Using the binding or multifunction buttons, a binding 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 at certain intervals.
If the transmit signal is missing, the central apartment unit will display an error
message.
If radio communication between the central apartment unit and the system compo-
nents to be controlled is interrupted, control is no longer ensured.
If communication breaks down, the position of the actuators connected to an
RRV912 / RRV918 heating circuit controller or RRV934 multi-controller is main-
tained and can only be changed manually through mechanical action on the actua-
tors.
Using the built-in room temperature sensor, the SSA955 radiator control valves
continue to provide control, maintaining a room temperature setpoint of 21 °C.
The ventilation plant continues to operate at the current stage for another 30 min-
utes and then shuts down.
The RF adapter plugs can be switched via external buttons (GAMMA wave), hand-
held transmitters (GAMMA wave) or directly with the plug’s own function button.
When radio communication is reestablished, the system components will resume
normal control operation
In the event power supply to the central apartment unit is interrupted, control is no
longer ensured.
If there is a mains failure, the positions of the actuators connected to an RRV912 /
RRV918 heating circuit controller or RRV934 multi-controller are maintained and
can only be changed manually through mechanical action on the actuators.
Using the built-in room temperature sensor, the SSA955 radiator control valves
continue to provide control, maintaining a room temperature setpoint of 21 °C.
The ventilation plant continues to operate at the current stage for another 30 min-
utes and then shuts down. With the air conditioner, the equipment’s own remote
control can be used for operation.
The RF adapter plugs can be switched via external buttons (GAMMA wave), hand-
held transmitters (GAMMA wave) or directly with the plug’s own function button.
