10. REMOTE CONDENSERS

The new Climaveneta's remote condensers NCE type are
available within three different acoustical versions:
standard version /B
low-noise version /LN
super-silenced version /SL
All versions are available for both horizontal (H) and vertical (V)
air fl ow installation.
The NCE remote condensers are provided with a single ventila-
tion management. The choice of the number of circuits affects
the refrigerant connections and / or the quantity of electrical
signals provided to the fans speed management, according to
the selected version.
Standard version (/B)
Unit equipped with 6 poles motor fan and D connections (Del-
ta).
Fan speed management based on phase cutoff control is avai-
lable as option. In this confi guration the units comes standard
with a built-in electrical board.
Low-noise version (/LN)
Unit equipped with 6 poles motor fan and Y connections
(Star).
Fan speed management based on phase cutoff control is avai-
lable as option. In this confi guration the units comes standard

10.1 Electrical board
The NCE remote condensers come standard without any elec-
trical board. The NCE are provided with a junction box which
includes the electrical connections of the fans.
The electrical board is provided as standard with all the fans
speed management options (phase cutoff signal and inverter
control), provided with all here below listed components:
main switch
fuses on mains
system on/off light signalling
power contactor for fans on/off
control circuit transformer
protection fuses on both primary and secondary circuits
auxiliary relay for thermal protection remote signalling.
