3. Electrical Connections
The control unit is supplied with all normally closed inputs shunted to common. Before connecting a device to the control unit, remove the shunt corresponding to the equipment to be wired, leaving the others unchanged.
- Power Supply: Connect the power cable between terminals 10 and 11. The unit requires a 230 Vac, 50Hz power supply. Ensure a suitable disconnection device is used.
- Courtesy Light: Connect an optional courtesy light between terminals 12 and 13. This output can power a 230Vac 500W MAX load and will remain active for 3 minutes after each movement command (up or down).
- Motor Connections: Connect the motor's neutral to terminal 14, phase 1 to terminal 15, and phase 2 to terminal 16. Verify motor wiring for correct installation.
- STOP Button: Connect a normally closed STOP contact between terminals 1 and 2. If unused, shunt terminal 1 to terminal 2. An open STOP input will cause the automation to stop automatically.
- OPEN Button: Connect the OPEN button between terminals 2 and 3. Leave open if unused. Activating the OPEN button sends an opening command to the automation.
- CLOSE Button: Connect the CLOSE button between terminals 2 and 4. Leave open if unused. Activating the CLOSE button sends a closing command to the automation.
- Photocell: Connect a normally closed photocell contact (PHOTO) between terminals 2 and 5. If unused, shunt terminal 2 to terminal 5. The photocell can cause the automation to stop or reverse movement.
- Accessories Power: Connect accessories to terminals 6 and 7. The control unit provides a 24 Vdc voltage.
- Flashing Light: Connect an optional flashing light with an auto-flashing circuit between terminals L 10 (input phase) and N 14 (motor neutral). The output activates simultaneously with the motor.
4. Indicator LEDs
- Power On: Lights up when the unit is powered.
- Photo: Lights up if the photocell contact is closed.
- Stop: Lights up if the stop contact is closed.
5. Preliminary Checks
Preliminary checks should be performed by qualified personnel. Correct motor wiring is crucial for proper automation operation.
- After checking wiring and ensuring no short circuits, unlock the motor and power the system. Check the status of the "photo" and "stop" indicator LEDs. All normally closed inputs should have their corresponding LED lit.
- Press the wired OPEN button. The automation should operate in the opening direction.
- Press the wired CLOSE button. The automation should operate in the closing direction. If not, invert the connections between terminals 15 and 16.

- Press and release the RADIO LEARN button on the control unit. The buzzer will emit long beeps every second.
- Press and release the UP button on the remote control. The buzzer will emit a short beep.
- Wait a few seconds for automatic memorization of the DOWN button, or press and release the DOWN button on the remote control. The buzzer will emit a short beep followed by two long beeps and two short beeps.
Both buttons are memorized, and the procedure is complete. Repeat the procedure to learn a new transmitter.
6.2 Learning a three-button transmitter
- STOP AUTOMATION: Ensure the automation is stopped.
- Press and release the RADIO LEARN button on the control unit. The buzzer will emit long beeps every second.
- Press and release the UP button on the remote control. The buzzer will emit a short beep.
- Press and release the STOP button on the remote control. The buzzer will emit a short beep.
- Press and release the DOWN button on the remote control. The buzzer will emit a short beep followed by two long beeps and two short beeps.
All three buttons are memorized, and the procedure is complete. Repeat the procedure to learn a new transmitter.
Note: If the buzzer emits a long beep and two short beeps, the transmitter was already memorized. If no signal is emitted, verify that the remote control is functioning and is from the B.ro series.
7. Functions Selectable by Dip-Switch
IMPORTANT: Change dip-switch settings only when the unit is powered OFF. Disconnect power before changing configuration.
7.1 Opening/Closing Function
This function allows you to choose the opening/closing mode of the automation:
- Dip 1 ON: Automation operates in impulse opening mode.
- Dip 1 OFF: Automation operates in manual (dead man) opening mode.
- Dip 2 ON: Automation operates in impulse closing mode.
- Dip 2 OFF: Automation operates in manual (dead man) closing mode.
The impulse mode (Dip 4) can be selected for the impulse function.
7.2 Operating Time
- Dip 3 ON: Infinite operating time. The output remains active until a stop or reverse movement command is received.
- Dip 3 OFF: Operating time is manually set by the "Run Timer" trimmer (see paragraph 6).
7.3 Impulse Function
When Dip 1 and Dip 2 are set to ON, the following functions are activated:
- "GO" Function: The automation operates in a step-by-step mode with a single button. The UP button executes the open-stop-close sequence. The DOWN button (or STOP on a 3-button remote) stops the automation.
- Two-button open-close: Pressing the UP button opens the automation, and a subsequent closing command (stop) halts it. Pressing the DOWN button closes the automation.
The "GO" function is automatically excluded if Dip 1 and/or Dip 2 are set to ON.

Warnings and Advice
- Avoid running control, safety, and input cables near 230V and motor power cables.
- Some 230V terminals carry dangerous voltages. Installation and programming must be performed by qualified personnel only.
- Use an all-pole disconnection device for the control unit's power supply, such as a switch with a minimum 3mm gap between poles, or an integrated device in the power supply network.
- Use double-insulated cable with a minimum conductor section of 1 mm² and a maximum of 2.5 mm² for connecting the unit and motors to the power supply.
- Metal parts or humidity in walls can negatively affect the system's range. Avoid installing the receiver and/or transmitters near large metal objects or close to the ground. An optimized antenna is necessary for maximum range; otherwise, the range will be reduced. If the supplied cable is too short, do not make splices. Replace it with a cable of the same impedance (50 Ohm, RG58 type) and necessary length, not exceeding 10m. This control unit is equipped with a photocell test circuit.
