Warning: carefully follow all the connection instruc-
tions. If you have any doubts do not make experiments but
consult the relevant technical specifications sheets which
are also available on the web site www.niceforyou.com.

2.1.3) Notes regarding connections
The control unit features two low voltage (24Vdc) supply terminals
(8-9) for the services (photocell). Three additional terminals (10-11-
12) are designated for the command and/or security inputs; as for
the latter, the 0 volt terminal (8) is the common one. Some of these
inputs have functions that depend on the programmed settings.
SECURITY DEVICES input
This input is designed for connection of the security devices. The
input can be used with normally closed (NC) as well as normally
open (NO) contacts or constant resistance contacts (8.2KΩ). To set
dip-switches 3-4 based on the type of input used, refer to the "Pro-
grammable Functions" chapter. The LED by the input will light up to
signal that the movement is enabled.
STEP-BY-STEP input
Each command on this input activates the open – stop – close –
stop -..... sequence. In this mode, if the command is maintained for
over 3 seconds (but less than 10), an opening manoeuvre will always
be activated, if it is maintained for over 10 seconds, a closing
manoeuvre will always be activated.
An incorrect connection may cause serious damage to the
control unit. Do not connect multiple motors in parallel
unless specifically required by the type of motor; if neces-
sary, use the appropriate expansion cards.
Description
= motor control output (close, common, open, earth)
= mains power supply line (earth, phase, neutral)
= 24Vdc output (services) max 50mA
= input for security devices (STOP / PHOTOCELL)
= input for cyclic command (open-stop-close-stop) or TTBUS connection
= input for closing command
= radio receiver aerial input
This function can be used to "synchronize" multiple control units,
commanded in parallel, in the same direction regardless of their cur-
rent status.
This input can be programmed as "open" (dip sw 2 ON ).
In this case, each command carries out the open - stop - close -
stop - ... sequence.
The step-by-step input is also the TTBUS communication input.
The "TTBUS" is a bus that has been developed for the management
of control units for awnings, rolling shutters and motors with preset
control unit. This Bus enables separate control of up to 100 control
units by connecting them in parallel using only 2 wires. For further
information, see the operating instructions for the remote controls via
"TTBUS".
CLOSE input
A command on this input always activates the close - stop - open -
stop... sequence. This input is also used to activate automatic re-
closing (with timed clock).
