1) Product description

The TT2N control unit enables the control of a single phase asyn-
chronous motor, mains powered, with connection types: Down,
Common, Up, used for the automation of awnings, rolling shutters
and similar.
The TT2N control unit incorporates a radio receiver that operates at
the frequency of 433.92 MHz with rolling code technology to guar-
antee optimal safety levels.
Each control unit can memorise up to 30 transmitters in the series
ERGO, PLANO and NICEWAY (figure 1), which enable the remote
control of the unit. In the 30 transmitters, a maximum of 3 VOLO S
RADIO climatic radio sensors can be memorised, for the automatic
control of the control unit according to weather conditions.
After each command the motor is powered for approx. 150 sec-
onds; this time interval can be modified (chapter 4.3 Work time). Dur-
ing this interval, the electric limit switch in the motor stops movement
at the set position.
The control unit is equipped with an input "P/B" for control of the unit
also by means of and external pushbutton.
Memorisation and programming is possible via the transmitters or
direct via the programming pushbutton (figure 2) on the TT2N. The
user is guided through the various phases by means of led signals.

tothermal and differential switches.
• A disconnection device must be inserted in the power supply line
from the electrical mains (the distance between the contacts must
be at least 3.5 mm with an overvoltage category of III) or equivalent
