Simultaneous operation on several indoor units for more homogeneous climatization in large
open spaces
With UTOPIA Prime is possible for several indoor units connected to a same outdoor unit to operate with the same
operation parameters and setting temperature, as it was a single indoor unit.
All indoor units are at the same Thermo-ON or Thermo-OFF status.
Simultaneous operation improves comfort versus monosplit PAC applications by providing a better air homogeneity
due to the bigger number of indoor units (up to 4), which means a less centralized air ow. Compared versus another
alternatives as multisplits provides longer piping distances needed for tertiary applications; compared to mini VRF
systems it is a more cost efcient solution.
Example for common room (Simultaneous operation).

Reduction of local temperature irregularity and achievement of optimal room conditions
With UTOPIA IVX Prime range it is possible a individual thermo-ON/OFF control, enabling control of multiple indoor units
by one remote control switch. The air conditioning operation is adjusted to control the room temperature as appropriate,
according to the different air-conditioning loads required for the interior zone and the perimeter zone of each room. As a
result, this function provides comfortable air conditioning (achieving uniform temperatures) and energy-saving.
• Interior Zone: a zone where temperature is not affected by direct sunlight or outdoor air inow
• Perimeter Zone: a zone where temperature is affected by direct sunlight or outdoor air inow
Example for one room (Individual operation with one remote control and operating cable for remote control):

Easy rearrangement for individual rooms
With UTOPIA IVX Prime range a multiple indoor units can be installed and operated individually even if rooms are
partitioned. Individual operation can be controlled for each room by connecting the remote control switch to each
indoor unit. It is possible to operate the indoor units of occupied rooms only, resulting in energy saving and exibility for
rearrangement of partitions.
Example for multiple rooms (Individual operation).
