ELECTRICAL CONNECTIONS AND
FIRST POWER UP
The electrical connections must be made only after installing the motor and compat-
ible accessories required.
The electrical cord of the motor is made up of the following internal cables (fig. 3):

2 White Counter-clockwise rotation pushbutton / TTBus
3 White-black Common (for bus wires)

4.1 - Connection of motor to electricity mains
Utilise cords 4, 5, 6 (fig. 3) to connect the motor to the main and pay attention to
the warnings:
– improper connection can cause breakdowns and hazardous situations;
– scrupulously respect the connections indicated in this manual;
– in the power supply network of the motor you must install a disconnection device
having an opening distance of the contacts that allows complete disconnection
in the overvoltage category III conditions, in conformity with the installation rules
(disconnection device not supplied with the product).
4.2 - Connection of accessories to motor
Accessories can be connected by cable: use cables 1, 2, 3 (fig. 3) to connect
the accessories to the motor; refer to fig. 3 of Chapter 6 - "Optional Accessories"
and pay attention to the following warnings:
– CAUTION! – The maximum length of the cables used to connect a wall-
mounted panel or a relay, is 100 m.
– Cables 1, 2, 3 of the bus lines MUST NOT be connected to be electrical mains.
– To the White + White-black lead you can connect only one accessory at a time
from among the compatible ones.
– To the White-orange + White-black lead you can connect only one accessory at a
time from among the compatible ones.
– The Open and Flows inputs are constrained to reach other, in other words they
must be used with the same pushbutton strip (fig. 3). As an alternative, if only the
White lead is available, you can use the step-by-step input.
Accessories can be connected by a radio (portable transmitters and certain cli-
matic sensor models): memorise these accessories in the motor during the program-
ming phases; refer to the procedures given in this manual (procedure 5.11) and
those given in the manuals supplied with the devices.

PROGRAMMING AND ADJUSTMENTS
5.1 - Transmitter to the used for programming
procedures
• The programming procedures can be performed exclusively with a Nice
transmitter having at least the following keys s, n, t.
• The programming procedures must be performed exclusively with a transmitter
memorised in "Mode I" (paragraph 5.5 or 5.10.1).
• If the transmitter used for programming controls multiple automation units, you
must select the "unit" corresponding to the automation you are programming be-
fore sending a command during a procedure.
5.2 - Positions in which the awning stops
automatically
The electronic system that controls the awning movement at all times can automati-
cally stop the movement when the awning reaches a certain position programmed
by the installer. The programmable positions are (fig. 6):
– position "0" = upper limit switch: totally wound awning;
– position "1" = lower limit switch: totally unwound awning;
– position "H" = intermediate position: partially open awning.
When the limit switches are not programmed yet, the awning can be moved only in
the "hold-to-run" mode, i.e. keeping the control key pressed for the desired duration
of the manoeuvre; the movement stops as soon as the user releases the key. How-
ever, after programming the limit switches, briefly pressing the appropriate key will
start the awning and it will stop moving automatically as soon as the awning reaches
the required position.
To adjust the distances "0" and "1" various procedures are possible; to choose the
appropriate one, take into account the supporting structure of your awning (see the
summary in the table).

WARNING! – If you want to again adjust again the height of the limit switch-
es adjusted previously, consider the following:
ac
– If you would like to adjust them with an alternative procedure different
ac
from the one used previously, you must FIRST delete the heights by follow-
ing procedure 5.16.
– If you wish to adjust them with the same procedure used previously, you
need not delete them.
The programming of the limit switches simultaneously combines the two directions
of rotation of the motor to the respective shutter raising key (s) and shutter lowering
key (t) of the control device (initially, when the limit switches are not programmed
yet, the combination is random and it can happen that when pressing the s key, the
shutter moves down instead of up, or vice versa).

5.3 - General warnings

• The limit switch must be adjusted after installing the motor in the awning and con-
necting it to the power supply.
• In cases of installations with several motors and/or receivers, before starting to
program you must disconnect the electrical supply to the motors and receivers you
do not wish to program.
• Scrupulously respect the time limits indicated in the procedures: after releasing a
key, you have 60 seconds to press the next key indicated in the procedure; other-
wise, when the time is up, the motor will perform six movements to communicate
cancellation of the procedure in progress.
• During programming, the motor performs a certain number of brief movements,
as a "response" to the command sent to the installer. It is important to count the
number of these movements without considering the direction in which they are
performed.
• Every time the motor is powered, 2 movements are performed if at least one trans-
mitter and the limit switch heights are not in the memory.
5.4 - Overview of the transmitters
5.4.1 - Compatible transmitters
Consult the Nice product catalogue or go to www.niceforyou.com to find the Nice
devices compatible with the radio receiver built into the motor.
5.4.2 - Transmitter memorisation hierarchy
In general a transmitter can be memorised as a FIRST transmitter or a SECOND
transmitter (or third, fourth, etc.).
A - First transmitter
A transmitter can be memorised as a first transmitter only if in the motor no
other transmitter is memorised. For this memorisation, follow procedure 5.5 (this
memorises the transmitter in "Mode I".
B - Second (or third, fourth, etc.) transmitting device
A portable transmitter (or a radio climate sensor) can be memorised as a second
(or third, fourth, etc.) transmitting device only if the First Transmitter is already
memorised in the motor. For this memorisation, follow one of the procedures
given in section 5.10.
5.4.3 - Two procedures to memorise the keys of a transmitter
To memorise the keys of a transmitter, two different procedures can be used: "Mode
I" and "Mode II".
• "MODE I" – This mode automatically transfers, the various commands available in
the motor, all together, into the various keys available on the transmitter, without
allowing the installer to change the combinations of commands and keys. Upon
completion of the procedure, each key will be combined with a command accord-
ing to the following diagram.
- key s (or key 1): will be combined with Raise
- key n (or key 2): will be combined with the command Stop
- key t (or key 3): will be combined with the command Lower
(if there is a fourth key on the transmitter .....)
- key 4: will be combined with the command Stop
Note – If the keys of your transmitter have no symbols or numbers, see fig. 2 to
identify them.
• "MODE II" – This mode allows you to manually combine one of the commands
available in the motor with one of the transmitter keys, giving the installer the option
of choosing the command and key combinations to use. At the end of the proce-
dure, to memorise another key with another command desired, it will be necessary
to repeat the procedure once again.
