Features and Benefits
Comfort and ease of installation
Improved connectivity (up to 4 indoors per outdoor unit, minimising pipework required) and zone-by-zone individual control makes IVX Comfort the perfect solution where VRF flexibility is needed but at a lower cost.
The individual Thermo-on and Thermo-off is possible even when the remote control is connected to multiple internal units.
The system is able to handle changes in air conditioning needs for each individual space, e.g., internal zone or perimeter area, and thereby
optimise energy efficiencies.
This produces a highly comfortable environment and great electricity savings.
Easily adaptable and reconfigurable
Each indoor unit can be operated completely independently within the same mode.
Controlled from a dedicated remote controller, each room’s occupants can monitor and adjust operating temperatures according to their specific requirements.
This facilitates maximum energy savings and total future flexibility, as units have individual control regardless
of possible future reorganisation of the interior spaces.
Compatibility with R22 pipework
New Utopia IVX Comfort (and IVX Premium) are compatible* with existing R22 gas installations. Both models – which use R410A refrigerant gas – can be installed without having to change the existing installed piping as the system adjusts the pressure so as
not to damage the existing piping.
