2. Product Description

The BiDi-Switch micromodule allows you to switch up to 2 electrical appliances powered by the mains on/off.

The BiDi-Switch micromodule integrates a radio transmitter-receiver that operates on the 433.92 MHz frequency with rolling code technology for optimal security levels. Each control unit can memorize up to 30 mono or bidirectional transmitters from the MyGO, DOMI, ERA, ERGO, FLOR, NICEWAY, and VERY series.

Two buttons are used on each transmitter: one for the ON/OFF command of the first output and one for the ON/OFF command of the second output. The micromodule memorizes the ON-OFF status of the connected devices, so in case of power failure, when the power is restored, the output returns to the previous state.

The micromodule is equipped with two inputs to control the two outputs using push-button switches.

Memorization and programming are possible via the programming button (figure 1) on the BiDi-Switch. The user is guided through the different programming phases by LED signals.

The micromodule is equipped with overload and overheat protection, which will disable the relays to prevent damage to the circuit.

3. Installation

WARNING! The product is subject to dangerous electrical voltages.

The installation of the BiDi-Switch and automation systems must be carried out exclusively by technically qualified personnel, in compliance with current legislation and standards, and according to these instructions. All connections must be made when the system is disconnected from the power supply.

The BiDi-Switch micromodule has been specifically designed to be inserted into a junction box or wall box; its housing offers no protection against water. It only provides basic protection against contact with solid parts. Never place the BiDi-Switch in insufficiently protected environments.

Never open or pierce the BiDi-Switch housing; it is subject to electrical voltages.

3.1 - Preliminary Checks

• The power line must be protected by appropriate magnetic-thermal circuit breakers (compliant with IEC / EN 60898-1 standard, up to 16 A) and differential circuit breakers.
• A disconnection device must be inserted in the mains power line (the contact distance must be at least 3 mm with overvoltage category III) or an equivalent system, e.g., a plug and socket. If the mains disconnection device is not mounted near the automation, it must be equipped with a locking system to prevent any unintentional and unauthorized connection.

3.2 - Electrical Connections

WARNING! Carefully follow all connection instructions. If in doubt, do not experiment but consult the corresponding technical specifications, which are also available on the website: www.niceforyou.com. An incorrect connection can be dangerous and damage the system.

3.3 - Electrical Appliances

The first appliance to be controlled must be connected between the neutral (N) and terminal 01; the second appliance must be connected between the neutral (N) and terminal O2 of the micromodule; the appliances are powered directly by the micromodule.

3.4 - Power Supply

The micromodule's power supply must be connected to terminals L and N (phase, neutral). The BiDi-Switch micromodule can operate with a supply voltage of 100 to 240 Volts and a frequency of 50 or 60 Hz.

3.5 - Switch and Push-button

If necessary, a switch or push-button can be connected to terminals S1 and S2, which can directly control the outputs. The switches are connected between the neutral (N) and terminals S1 and S2 as shown in figure 2. The switch connected to S1 is responsible for command 01, and the switch connected to S2 is responsible for command 02. Rocker or impulse switches can be connected to terminals S1 and S2, but the micromodule's operation may need to be adjusted according to the type of switch connected. To check and change the switch type, see table A10.

WARNING! Switches are powered by mains voltage and must therefore be properly protected and insulated.

4. Transmitter Memorization

This chapter describes the memorization procedures in Mode I, used to control a single automation with the 2 transmitter buttons, and in Mode II, used to control an automation with a single button, leaving the other buttons free for controlling other automations.

• The button corresponds to the central button of ERGO, PLANO, NICEWAY, and DOMI transmitters.
• All memorization sequences are timed, meaning they must be completed within the allotted time.
• With transmitters that operate with multiple "groups", the group to be associated with the module must be selected before proceeding.
• Radio settings are possible on all micromodules within the transmitter's operating range, and therefore, only the device necessary for the operation should remain powered.

4.1 - Mode I

In Mode I, the command associated with the transmitter buttons is fixed (table A1). In Mode I, a single memorization phase is performed for each transmitter, and only one memory location is occupied. When memorizing in Mode I, the button pressed on the transmitter does not matter.

Table A1 - Memorization in Mode I

4.2 - Transmitter Memorization in Mode I

When no transmitter is memorized, the first one can be memorized at startup according to the following procedure.

Table A2 - Memorization of the first transmitter at startup in Mode I

1. Connect the micromodule to the mains, confirmed by 2 red flashes.
2. Within 10 seconds:
   • Monodirectional transmitters: press and hold any button on the transmitter to be memorized for at least 3 seconds.
   • Bidirectional transmitters: press any button on the transmitter to be memorized.
3. If the memorization procedure is successful, the LED emits 3 red flashes.

If no transmitter needs to be memorized at startup, the programming procedure ends automatically after 10 seconds, and the LED emits a long red flash.

Transmitters can be memorized using the programming button according to the following procedure.

Table A3 - Memorization of the first transmitter and other transmitters in Mode I

1. Press and hold the programming button (fig. 1).
2. Release the programming button (fig. 1) when the LED lights up red (1st position).
3. Within 10 seconds:
   • Monodirectional transmitters: press and hold any button on the transmitter to be memorized for at least 3 seconds.
   • Bidirectional transmitters: press any button on the transmitter to be memorized.
4. If the memorization procedure is successful, the LED emits 3 red flashes.
5. Repeat steps 3 and 4 to add other transmitters.
6. After 10 seconds without the device receiving any signal, the programming procedure ends automatically.

If transmitters have already been memorized, other transmitters can be memorized as described in the following procedure.

Table A4 - Memorization of new transmitters with a previously memorized transmitter in Mode I

1. Press any button on a previously memorized transmitter three times.
2. Press the same button on a new transmitter three times.
3. Press any button on a previously memorized transmitter three times.
4. Press the same button on the new transmitter.
5. If the memorization procedure is successful, the LED emits 3 red flashes.
6. The programming procedure ends automatically.

Note: If the memory is full (30 memorized transmitters), 6 red flashes are emitted, and the transmitter cannot be memorized.

4.3 - Mode II

In Mode II, each transmitter button can be associated with one of the 6 possible commands (table A5); for example, an automation can be controlled with a single memorized button for the ON/OFF output 1 command, while the other buttons are left free for controlling other automations. In Mode II, one memorization phase is performed for each button, and each occupies a memory location. During Mode II memorization, the specific button pressed is memorized. If another button needs to receive a command on the same transmitter, a new memorization phase must be performed for that specific button.

Table A5 - Memorization in Mode II

4.4 - Transmitter Memorization in Mode II

Table A6 - Memorization of the first transmitter and other transmitters in Mode II

1. Press and hold the programming button (fig. 1).
2. Release the programming button (fig. 1) when the LED lights up orange (2nd position).
3. Press the programming button the number of times corresponding to the desired command (1 = ON output 1, 2 = OFF output 1, 3 = ON/OFF output 1, 4 = ON output 2, 5 = OFF output 2, 6 = ON/OFF output 2).
4. Check that the LED emits the number of long orange flashes corresponding to the desired command.
5. Within 10 seconds:
   • Monodirectional transmitters: press and hold the desired button on the transmitter to be memorized for at least 3 seconds.
   • Bidirectional transmitters: press the desired button on the transmitter to be memorized.
6. If the memorization procedure is successful, the LED emits 3 orange flashes.
7. Repeat steps 5 and 6 to acquire all transmitters with the same command.
8. Repeat steps 3 to 6 to acquire all transmitters with another command.
9. After 10 seconds without the device receiving any signal, the programming procedure ends automatically.

Note: If the memory is full (30 memorized transmitters), 6 orange flashes are emitted, and the transmitter cannot be memorized.

4.5 - Memorizing a New Transmitter Using the "Activation Code" of an Already Memorized Transmitter

The bidirectional transmitter has a secret code called the "activation code". By transferring the code from a memorized transmitter to a new transmitter, the latter is automatically recognized (and memorized) by the micromodule. Refer to the transmitter manual for more details.

Attention! The activation code can only be transferred between two transmitters with the same radio coding.

Table A7 - Transmission of the "activation code"

1. Bring the previously memorized transmitter and the new transmitter close together.
2. On the new transmitter, press the command button. The previous transmitter's LED will light up and start flashing.
3. On the previous transmitter, press the command button.
4. Once the code is transferred, the two transmitters will vibrate momentarily, and the green LED will light up to signal the end of the procedure.

When the new transmitter is used, for the first 20 times, it will transmit this "activation code" to the receiver with the command. The receiver will automatically memorize the identification code of the transmitter that transmitted it.
