30 SQ
Low Energy Consumption Fan Motor version
SQ...units can ensure a 0% - 100% constant air flow modulation
(and therefore the thermal and refrigerating capacity) thanks to
the Inverter technology combined with the last generation of high
energy-efficient electric motors (EC brushless). This enables a
constant control on the power supplied according to the room that
needs to be conditioned.
The result is 50% electric energy saving compared to traditional
3-speed asynchronous motors and a considerable reduction
of acoustic emissions. The table below shows the electrical
characteristics of the four types of motors.

NOTE:
• The values showed in the table are reported only at the Low Energy
Consumption Fan Motor. It is necessary to add the control input power
which corresponds to about 5W ("IR Control"), 9W for the pump and
3W or 6W for the valves (4 pipes).
No further electrical connections are necessary (beside power
supply and communication bus) for this unit (fig.39).
All connections between electric components and motor are factory
made.
