Power Supply - Nice TT2L Instructions Et Recommandations Pour L'installateur

2.2.2) Power supply

The electric power supply of the control unit must be connected by means of terminals 5 and 6 (Phase, Neutral). The TT2L and TT2D con-
trol units can operate with either supply voltages of 120 or 230 V and frequency of 50 or 60 Hz.
2.2.3) Input for On-Off contact
The TT2L and TT2D control units are preset to be connected to a
contact for On-Off manual controls. The contact must be connected
between phase (L) and terminal 4 as shown in figures 3a and 3b.
Either a switch or a pushbutton may be used. The operation is as fol-
lows: if the contact remains closed for less than 1 second, the com-
mand is given only when the contact closes, if the contact remains
3) Programming
To ensure that a transmitter can control the TT2L and TT2D units, the memorization procedure must be performed as described in table A1.
Memorization and settings can be entered via the transmitters (chapter 3.1) or directly via the programming pushbutton (chapter 3.2).
3.1) Settings via transmitters
• This chapter describes the memorization procedure in
Mode I, used to control a device with 2 keys of the trans-
mitters. Chapter 4.2 describes the memorization proce-
dure in Mode II, used to control a device with a single
key, thus leaving the other keys free for control of other
automations.
• All the memorization sequences are timed, i.e. they must
be completed within the programmed time limits.
• With transmitters that envisage several "groups", the
relative group to associate with the control unit must be
selected before proceeding.
• The memorization via radio may be performed on all the
receivers that are within the transmitter range; there-
fore, only the device required for the operation should
be switched on.
• Two keys are used for each transmitter: key 1 = On; key
2 = Off. On transmitters with 4 keys, those that are left
unused can be utilized to control another control unit:
key 3 = On and key 4 = Off.
When there is no transmitter memorized, the first can be memorized according to the following procedure.
Table "A1" Memorizing the first transmitter (in mode I)
1. Connect the control unit to the power mains, confirmed by 2 long flashes.
2. Within 5 seconds press and hold key 1 or 2 (or key 3 or 4) of the transmitter to be memorized
(for at least 3 seconds)
3. Release key on the first of the three flashes confirming memorization.
When one or more transmitters have already been memorized, others may be enabled as follows:
Table "A2" Memorization of additional transmitters in Mode I
1. Press and hold key 1 or 2 (or key 3 or 4) of the new transmitter (for at least 5 seconds)
confirmed by a long flash, after which release.
2. Slowly press key three times of a previous and memorized transmitter.
3. Press the key 1 or 2 (or key 3 or 4) of the new transmitter, and release on the first of
the 3 long flashes confirming memorization.
Note. If the memory is full (30 transmitters), 6 long flashes will indicate that the transmitter cannot be memorized.
4
closed for longer than 1 second, the command is given both when
the contact closes and when it opens.
As there is mains voltage on the contact, it must be prop-
erly isolated and protected.
• The ON command on the TT2L control unit is used to
switch the unit on, whereas the Off command is used to
switch the unit Off. On the TT2D control unit, the ON
command is used to turn the switch off between termi-
nals 2 and 3, while the Off command is used to turn the
switch off between terminals 1 and 2.
The user can check whether any transmitters are already memorized
on the TT2L and TT2D control units by simply checking the type of
flash sequence of the leds when the control unit is switched on.
