• After replacing the batteries, the small actuator returns to the factory setting (actuator spindle retracted). Upon receiving a radio signal, the device switches to normal operation.
• If the learning process is not completed within 1 hour, the SAB05 switches to self-control mode. The temperature is then controlled by the internal controller.

Functional Description

Radio Interface

Radio communication with the radio receiver is cyclical and bidirectional. After the first radio telegram is received (during programming with the radio receiver), the actuator automatically adjusts its operating mode depending on the radio receiver's control (actuator mode or self-regulation mode).

If radio communication with the radio receiver is interrupted, the "Self-regulation mode" status bit is set (can be used for service diagnostics). After this fault is rectified (details in the receiver documentation), synchronization is automatically performed.

NOTE: This product exclusively uses EnOcean radio telegrams. When selecting radio receivers, ensure that the radio interface is also compatible with the EnOcean radio telegram EEP A5-20-01 (battery-powered actuator).

Control according to manipulated variable (actuator movement)

If an EnOcean radio telegram for controlling the actuator's position is received from an external radio transceiver, the internal controller will not be active. The transmitted telegram is converted into a positioning movement. The corresponding wireless room controller takes over the control function.

Control according to setpoint and actual value

If an EnOcean radio telegram containing the setpoint and actual value is received from an external radio transceiver, the internal controller is activated. The actuator takes over the control function, the transmitted telegram is processed and converted into a positioning movement.

Loss of Communication (Emergency Self-Control)

If no valid telegram is received within 6 intervals, the valve actuator switches to emergency mode. The configured transmission interval does not change. In emergency mode, the valve actuator controls independently using the internal temperature sensor and a setpoint of 20 °C. Bit 0.2 (DB_0.BIT_2) is set to 1 in self-control mode.

Pay attention to the influence of the heating medium temperature on the internal temperature sensor.

Automatic Closing Point Control

The actuator continuously monitors the closing point and corrects it if necessary.

Frost Protection Function

If the temperature on the integrated temperature sensor drops below 6°C, the actuator opens the valve until a temperature of 8°C is reached.

Configuration via airConfig

After pressing the "Learn" button, all parameters will be read and displayed in airConfig. The [Device] section contains information about internal values and set parameters. Important configuration parameters can be set in the [Send] section.

Device Type: The type of the small actuator is automatically detected and assigned.

Operation: Describes the operating mode.

Version Dolphin / Version ATmega / Master ID: Displays information about the firmware version numbers of Dolphin and ATmega in the device. The Master ID is also read and displayed.

Device Status: The values shown in this section are updated with each wake-up. The measured temperature of the internal temperature sensor is displayed. It serves for internal frost protection (see functions). The current valve position is given in %. The battery voltage indicates its status. OK for >3.6 V (SAB05).

Actuator Status Options

• Window open: Detected open window, valve closes and returns to normal operation after 30 minutes. (See Window Open Detection)
• Blockage / Blockage: Actuator reports blockage if it cannot reach the desired position.
• Regeln / Active: Actuator operates normally. If the battery capacity drops below 10%, it is deactivated, and the actuator spindle assumes the 50% safety position.
• Temperature Sensor Failure: Error message from the internal temperature sensor.
• Battery Capacity / Low battery: Battery capacity is constantly monitored. If the battery charge level is too low, the radio transceiver is notified wirelessly, and a double beep is emitted every 6 hours. If this message is active, the remaining battery capacity is <10%.

WARNING: Battery replacement must be performed within the next 30 days.

As the battery capacity decreases, the intervals between acoustic signals become shorter, and the number of beeps increases to 4 x 1 beep every 3 hours. If the remaining battery capacity is insufficient to power the motor, the drive switches to the 50% safety position. In this operating state, radio communication with the radio transceiver is maintained.

• Service (Interruption of Radio Communication): If radio communication with the radio transceiver is interrupted for more than 60 minutes, the radio actuator switches to self-control mode, and the "Self-control mode" status bit is set with the next telegram. Upon receiving a valid radio telegram, the radio actuator automatically returns to normal operation.
• Position Interpolation: If position interpolation is active, valve positions are interpolated. This means the actuator reaches the desired valve position only after several intermediate steps. Parameters can be activated in the [Send] section.
• Summer Mode Detection / Automatic summer mode detection: When a "Summer Mode On" status message is received from the external radio receiver, the actuator closes the valve. The transmission/reception interval is set to 60 minutes during the summer period.
• Valve Block Protection / Valve Protection: Valve block protection prevents the valve from seizing during long periods of inactivity. After activation of the valve block protection, the actuator performs a 50% stroke change every 21 days and returns to the initial position. If the remaining battery capacity is <10%, this function is inactive. Parameters can be activated via the [Send] section and via key configuration (see commissioning).
• Configuration Report / Auto Send Configuration: If this function is enabled, the actuator sends its configuration every 24 hours. The configuration can be retrieved via airConfig or gateway. Parameters can be activated via the [Send] section.

Note on Window Detection (Energy Blockade) is not recommended

When a window is opened, the heat supply to the room is interrupted. With an open window, a sudden and rapid temperature drop is detected by the internal temperature sensor. In this case, the valve is closed for 30 minutes. This setting is not recommended, as the actuator cannot be controlled during this time. After 30 minutes, the actuator returns to normal operation, and the "Window Open" automatic detection function is active again.

If the remaining battery capacity is <10% (see "Battery Capacity" parameter), this function is inactive.

Parameters can be activated via the [Send] section and via key configuration (see commissioning).

Configuration via airConfig - Detailed Settings

Counter / Counter: The [Counter] section contains internal information, e.g., valve stroke counter, FlyWheel Timer, and communication information.

Special / Special: The actuator detects the closing point and the total valve stroke during the initialization run performed during commissioning.

After battery replacement or successful pairing with a radio transceiver, the closing point detection is performed again via an initialization run.

The currently set control parameters and signal strength are displayed here. Rule parameters can be configured in the [Send] section.

Transmit Clock / Transmit Clocking: Configurable 1..120 minutes

Device Settings / Device configuration: Parameters described in the [Device] section can be enabled or disabled here.

Tn/Xp: If the behavior of the controlled variable in a closed control loop is known from previous control processes, the control parameters can also be adapted based on the controlled variable's curve.

The diagram illustrates the configuration process using the Learn button and LED indicators.

NOTE: In addition to these instructions, the product descriptions of other system components must also be observed.

Device Assignment

IMPORTANT!

For the learning process, the SAB05 must be mounted on the heating valve.

This is important so that the actuator can perform the reference run without errors.

• Enable learning mode in the radio-compatible device (3). Details are described in the documentation of the radio transceiver.
• A radio telegram requesting the start of the Learn procedure must be sent from the actuator. To do this, press the actuator's button until you hear a beep and the status LED lights up green (4).
• Release the button after the LED lights up. The Learn process has started (5). The radio transceiver confirms the successful completion of the Learn procedure. Details are described in the documentation of the radio transceiver.
• The radio actuator confirms successful programming visually (2x green LED flashes) and acoustically (2x 1 beep) (6/7). An automatic initialization run is performed.
• Close the actuator housing by snapping the housing cover shut (8).

Note:

If the Learn process fails, it will be indicated visually (1x red LED flash for approx. 1 s) and acoustically with a rising sequence of sounds. The learning process must then be started again.

After successful programming, the device identifier of the radio transceiver is permanently stored in the radio actuator. Reprogramming after battery replacement is not necessary.

It is not possible to delete the internally stored device identifier of the radio transceiver in the actuator. It is overwritten with the corresponding radio identifier during each new learning process.

2 - Triggering Communication Test

• Press the button until you hear two consecutive beeps and the status LED flashes green twice, then release the button.
• After releasing the button, the radio connection to the configured radio transceiver is checked. A successful communication test is confirmed visually (2x green status LED flashes) and acoustically (2x 1 beep). A successful communication test results in the adjustment of the current valve position.
• If the communication test is negative, it is indicated visually (1x red status LED flash for approx. 1 s) and acoustically (falling sequence of sounds). The radio actuator has switched to emergency mode. If the communication test fails, check the transceiver and the radio connection.

3 - Activating and Deactivating Valve Block Protection (without airConfig)

• Press the button until you hear three consecutive beeps and the status LED flashes green three times. Then release the button.
• After releasing the button, the current ON or OFF status is indicated visually and acoustically.
• Valve Block Protection ON: 2x green status LED flashes and 2x 1 beep is heard.
• Valve Block Protection OFF: 1x red status LED flashes for approx. 1 s and a long beep.
• To change the status, press the button briefly again within 5 seconds.

The newly set "Valve Block Protection Enabled" or "Valve Block Protection Disabled" function is indicated visually and acoustically as described above. Factory setting: ON

4 - Activating and Deactivating Energy Blockade (Automatic "Window Open" Detection) (airConfig)

• Press the button until you hear four consecutive beeps and the status LED flashes green four times. Then release the button.

After releasing the button, the current ON or OFF status is indicated visually and acoustically.

• Energy Blockade ON: 2x green status LED flashes and 2x 1 beep is heard.
• Energy Blockade OFF: 1x red status LED flashes for approx. 1 s and a long beep.
• To change the status, press the button briefly again within 5 seconds.

The newly set "Energy Blockade Enabled" or "Energy Blockade Disabled" function is indicated visually and acoustically as described above. Factory setting: ON

5 - Setting Radio Interval (airConfig)

The transmission/reception interval of 2..20 min can be set in 2-minute steps.

• Press the button until you hear five consecutive beeps and the status LED flashes green 4 times and orange once. Then release the button.

After releasing the button, the currently set radio interval is indicated visually and acoustically:

To change the radio interval, press the button again within the next 5 seconds and only release it when the desired radio interval is reached. Visual and acoustic signaling, see "Radio Interval" table.

Release the button. The new radio interval is then confirmed visually and acoustically. Factory setting: Transmission/reception interval 10 min.

6 - Ending Configuration

If the button is pressed until "six" consecutive beeps are heard and the status LED flashes "6x green", the end of the settings will be signaled by a "red" flashing status LED and a long beep lasting approx. 1 second.
