2PRODUCT DESCRIPTION
The BiDi-Dimmer control unit enables the control of a single light source, mains powered. The light
source can be turned on/off and dimmed (if dimmable).
The control unit is equipped with an algorithm of a light source detection. It automatically selects suit-
able control mode and adjusts maximum and minimum light levels.
The BiDi-Dimmer control unit incorporates a radio transceiver that operates at the frequency of 433.92
MHz with rolling code technology to guarantee optimal safety levels.
Each control unit can memorise up to 30 mono or bidirectional transmitters in the series ERA, ERGO,
FLOR, NICEWAY and VERY, which enable the remote control of the unit.
The control unit is equipped with two inputs for controlling the unit by means of external switches.
Memorisation and programming is possible via the programming pushbutton (gure 1) on the BiDi-Dimmer.
The user is guided through the various phases by means of LED signals.
The control unit is equipped with overload, and overheating protection, which will disable the load to
prevent damage to the circuit.
3INSTALLATION
• The product is subject to hazardous electric voltages
• The installation of the BiDi-Dimmer and automations must be performed exclusively by technically qualied personnel, in
observance of current legislation and standards, and according to these instructions. All connections must be made with
the system disconnected from the power supply.
• The BiDi-Dimmer control unit has been especially designed for insertion in a junction box or wall box; its housing does not
feature any protection against water and only basic protection against contact with solid parts. Never place the BiDi-Dim-
mer in inadequately protected environments.
• BiDi-Dimmer can work in 3-wire (with Neutral line) or 2-wire (without Neutral line) installation.
• Never open or perforate the BiDi-Dimmer housing, this is subject to hazardous electric voltages!
3.1 - Preliminary checks
• The power supply line must be protected by suitable magneto-thermal (compliant with IEC/EN 60898-1 standard, rated up to 16A) and
residual-current circuit breakers.
• A disconnection device must be inserted in the power supply line from the electrical mains (the distance between the contacts must be at
least 3mm with an overvoltage category of III) or equivalent system, for example an outlet and relative plug. If the disconnection device for
the power supply is not mounted near the automation, it must have a locking system to prevent unintentional, unauthorized connection.
3.2 - Electrical connections
Carefully follow all the connection instructions. If you have any doubts do not make experiments but consult the relevant
technical specications which are also available on the web site: www.niceforyou.com. An incorrect connection may be danger-
ous and cause damage to the system.

3.3 - Light source
The light source to be controlled must be connected between neutral (N) and terminal ; the light source is powered directly by the control
unit.
Never connect more than one type of the light source per control unit!
3.4 - Power supply
The electric power supply of the control unit must be connected by means of terminals L and N (Live, Neutral) according to gure 2. If no Neu-
tral wire is present in the box, connect the N terminal with the Sx terminal according to gure 3. The BiDi-Dimmer control unit can operate with
supply voltage of 100 to 240 Volts and frequency of 50 or 60 Hz.
3.5 - Switches
If required, external switches can be connected to terminals S1 and S2, which can control the output directly. The switches are connected be-
tween Sx and terminals S1 and S2 as shown in gure 2 and 3. Toggle or momentary switches can be connected to S1 and S2 terminals, but
the operation of the control unit might need to be adjusted for the connected type of switch, to check and change the type of switch see table
A13. The response to the connected switches is as shown in the tables below (A1 for toggle switches, A2 for momentary switches).
Table A1 - Response to connected toggle switches (default)

The switches carry mains voltage and must therefore be adequately protected and insulated.
3.4 - LED Adaptor
The Nice LED Adaptor should be used in case of connecting LED bulbs or energy saving compact uorescent lamps. The LED Adaptor pre-
vents ickering of the LED lights and glowing of the turned off compact uorescent lamps. In the case of 2-wire connection, the LED Adaptor
allows to reduce minimum power of load required by the BiDi-Dimmer for correct operation. In such cases, connect the LED Adaptor in paral-
lel to the light source as shown in gure 2 and 3.
4MEMORISING TRANSMITTERS
• This chapter describes the memorisation procedures in Mode I, used to control a single automation with the 3 keys of the
transmitters and Mode II, used to control an automation with a single key, thus leaving the other keys free for control of
other automations.
• The key n corresponds to the central key of the transmitters ERGO, PLANO and NICEWAY.
• All memorisation sequences are timed, which means they must be completed within the set time limits.
• With transmitters that envisage several “groups”, the relative group to associate with the control unit must be selected
before proceeding.
• Settings via radio are possible on all receivers located within the operating radius of the transmitter, and therefore only the
device required for the operation should remain powered.
4.1 - Mode I
In Mode I the command associated with the transmitter keys is fixed (table A3). In Mode I only one memorisation phase is performed for each
transmitter and only one memory location is occupied. During memorisation in Mode I it is not important which key is pressed on the transmitter.
Table A3 - Memorisation using Mode I
Key Command
Key s or 1st channel Turn ON / Brighten UP (hold)
Key n or 2nd channel Toggle between OFF and the last level
Key t or 3rd channel Dimm OFF / Dimm down (hold)
Keys t + s or 1st + 3rd channels * Set favourite level (50% by default)
Slider (if equiped with) Set level
* Pressing two keys and the same time is not supported by some transmitters.
4.2 - Memorising transmitters in Mode I
When there is no transmitter memorised, the rst can be memorised during startup according to the following procedure.
Table A4 - Memorising rst transmitter during startup in Mode I Example
01. Connect the control unit to the power mains, conrmed by 2 red ashes.
02. Within 10 seconds:
• Monodirectional transmitters: press and hold any key of the transmitter to be memorized for at
least 3 seconds.
• Bidirectional transmitters: press any key of the transmitter to be memorized
MONO: 3s
BIDI:
03. If the memorisation procedure is successful, the LED emits 3 red ashes.
If no transmitters should be memorized during startup, the programming procedure concludes automatically after 10 seconds and the LED
emits one long red ash.
The transmitters can be memorised using the programming pushbutton according to the following procedure.
Table A5 - Memorising rst and other transmitters in Mode I Example
01. Press and hold the programming pushbutton.
02. Release the programming pushbutton when the LED illuminates with red color (1st position).
03. Within 10 seconds:
• Monodirectional transmitters: press and hold any key of the transmitter to be memorized for at
least 3 seconds.
• Bidirectional transmitters: press any key of the transmitter to be memorized
MONO: 3s
BIDI:
04. If the memorisation procedure is successful, the LED emits 3 red ashes.
05. Repeat steps 3 and 4 to acquire all the remotes.
06. After 10 seconds that the device doesn’t receive any signal, the programming procedure concludes auto-
matically.
If transmitters have already been memorised, other transmitters can be memorised as described in the following procedure.

Table A6 - Memorising other transmitters with a previously memorised transmitter in Mode I Example
01. Press any key three times of a previous, memorised transmitter. Old x3
02. Press the same key three times of a new transmitter. New x3
03. Press the same key three times of a previous, memorised transmitter. Old x3
04. Press the same key of the new transmitter. New
05. If the memorisation procedure is successful, the LED emits 3 red ashes.
06. The programming procedure concludes automatically.
Note. If the memory is full (30 transmitters memorised) 6 red flashes are emitted and the transmitter cannot be memorised.
4.3 - Mode II
In Mode II each key of the transmitter can be associated with one of 8 possible commands (table A7); for example, one automation can be
controlled with just one key memorised for the toggle command, while the other keys are left free for control of other automations. In Mode II
one memorisation phase is performed for each key and each occupies one location in the memory. During Mode II memorisation, the specific
key pressed is memorised. If another key is to be assigned a command on the same transmitter, a new memorisation phase must be performed
for that specific key.
Warning! - For the partial positions to work correctly, you must perform the calibration procedure (see chapter 5.1).
Table A7 - Memorisation using Mode II
Nº Command
1 Turn ON / Brighten UP (hold) *
2 Dimm OFF / Dimm down (hold) *
3 Toggle between OFF and the last level
4 OFF
5 Set 25%
6 Set 50%
7 Set 75%
8 ON

07. Repeat steps 5 and 6 to acquire all the remotes with the same command.
08. Repeat steps 3 to 6 to acquire all the remotes with another command.
09. After 10 seconds that the device doesn’t receive any signal, the programming procedure concludes auto-
matically.
Note. If the memory is full (30 transmitters memorised) 6 orange flashes are emitted and the transmitter cannot be memorised.

4.5 - Memorising a new transmitter using the “enabling code” of an already memorised transmitter
The bidirectional transmitter has a secret code, the so-called “enabling code”. By transferring this code from a memorized transmitter to a new
transmitter, the latter is recognized (and memorized) automatically by the control unit.
Warning! - The enabling code can only be transferred between two transmitters that have the same radio coding.
Table A9 - Transmitting the “enabling code” Example
01. Bring a previous, memorised transmitter and the new transmitter close to one another.
02. On the new transmitter press command key. The LED of the previous transmitter will switch on and start
ashing. New Old
03. On the previous transmitter press command key. Old
04. Once the code has been transferred, for an instant both the transmitters will vibrate and the green LED will
light up signalling end of the procedure.
When the new transmitter will be used, for the rst 20 times it will transmit this “enabling code” to the
receiver together with the command. The receiver will automatically memorize the identication code of the
transmitter that transmitted it
