1.2 DESCRIPTION
The product is a control unit to control electrical motors powered from the grid with power of max. 500 W
(230 V) or max. 250 W (110 V).
Ideal for activating motorised awnings, shutters and blinds with settable Up-Down-Stop, step and manual
modes.
The ISM (industrial, scientific and medical) radio frequency band guarantees a long range, even through walls
and ceilings.
Simple programming with dip-switches, reduced dimensions with breakable tabs (pic. 1.1c) for fixing with
screws (pic. 1.2a) or for insertion into connection boxes up to 55 mm in diameter (pic. 1.2b, 1.2c and 1.2d).

WARNING:
- The control unit is set up to control motors with internal end limit regulation.
- Buttons must be used for control via wire
- Multiple buttons or loads can be connected by using parallel cabling.
- If the condenser is not connected internally to the motor (typical of tubular motors), it is connected between
the phases (terminals 4 and 6). Refer to the motor manual
- It is important to respect the opening and closing phase of the motor to make the commands of the
transmitter and the wired inputs in mode 2 synchronise (see paragraph 4.1).
If the opening phase is not shown in the motor, carry out a test to check which wire it corresponds to.

3 USE OF THE CONTROL UNIT
To control the motor via radio you must have compatible transmitters and therefore must carry out the
association procedure; see paragraph 5.
The transmitter's command modes depend on the model used. If the transmitter is of a generic type,
its operation depends on the way it is programmed (see paragraph 5, table 5.3a).
If the transmitter is multifunctional, refer to the transmitter manual, to the paragraph entitled "commands sent
by the transmitter", bearing in mind that it is an "up-down-stop" device.
3.1 USE VIA RADIO
The device is set up to be able to accept commands via wire from buttons in terminals 3 and 4. Should you
wish to control the load only via radio, it is not necessary to connect these devices for the control unit to work
properly.
Default operation (Key P1 = Key P2):
DIP4 ON, step: with each press the motor will carry out an opening movement, a stop, a closing movement, a
stop, in sequence.
DIP4 OFF, manual operation: the motor will carry out its manoeuvres only with the key pressed down.
The motor will carry out an opening manoeuvre in sequence (when the key is released it will carry out a stop)
and a closing manoeuvre (when the key is released it will carry out a stop).
3.2 USE VIA WIRE
Default: mode 1
This procedure lets you select the function of inputs "P1" (terminal 3) and "P2" (terminal 4). WARNING: the
connected devices must be buttons.
PROCEDURE:
CONTROL MODES:
4.1 CONFIGURATION OF BUTTONS VIA WIRE
STEP 1
Position DIPs 1, 2 and 3
to OFF-ON-OFF
DIP 1, 2, 3=
OFF ON OFF
STEP 2
Press the button on the
receiver for a short time.
The LED comes on
and stays on
STEP 3
Press the button on the receiver for a short time
count the number of flashes emitted by the LED:
6 flashes = MODE 2 (P1= Open/stop P2= Close/stop)
3 flashes = MODE 1 (P1=P2= pen/stop/close/stop)

MANUAL OPERATION
The movements of the motor
occur only with the key
pressed down, when it is
released the control unit
carries out a stop
STEP 4
To change the setting, repeat the procedure from
point 1; the control unit will alternate between
3 and 6 flashes.
