3.2 - Electrical connections
Carefully follow all the connection instructions. If
you have any doubts do not make experiments but consult
the relevant technical specifications which are also
available on the web site: www.niceforyou.com. An
incorrect connection may be dangerous and cause
damage to the system.

3.3 - Motor connection
The single phase asynchronous motor connection to the mains must be via terminals O1-N-O2 (Up, Common, Down). Up corresponds to the
key
s
of the transmitters and S1 pushbutton, Down to key
t
and S2 pushbutton. After connecting, if the direction of motor rotation is incor-
rect, exchange the connections of terminals O1 and O2.
Never connect more than one motor 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). The BiDi-Shutter control unit
can operate with supply voltage of 100 to 240 Volts and frequency of 50 or 60 Hz.
3.5 - Pushbuttons
If required, external, momentary pushbuttons can be connected to terminals S1 and S2, which can control the unit directly. The pushbuttons
are connected between neutral (N) and terminals S1 and S2 as shown in figure 2. The pushbutton connected to S1 is responsible for Up
movement, and the pushbutton connected to S2 is responsible for Down movement.
The pushbuttons carry mains voltage and must therefore be adequately protected and insulated.

MEMORISING 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 A1). 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.
