RG66007967 - Rev 02

Double water circuit: 

-  Air conditioning circuit with reversible cooling circuit side and variable set-point between min/max with potential-free 

contact or with 0-10V or 4-20 mA signal.

-  Total heat recovery (for simultaneous cooling) or in any case prioritised DHW circuit. This circuit is separate and does 

not need long heating/cooling stages of inertial storage, like similar products on the market, which jeopardise energy 
efficiency especially during summer operation.

The basic selection when developing the range of multifunction units consists in using the following:
-  Scroll or twin-rotary compressors.
- Brazed plates.
- High-efficiency fans.
-  Electronic expansion valve.
-  AISI 316 Stainless steel high-efficiency plate heat exchangers.
-  Advanced electronic control allows load partialisation requirements to be adequately met.
For optimal partial load operation, which is ever more an object of evaluation and a discriminating factor in the technical 
choice of heating technicians.

The structure of the 

HiWarm

 units has the following characteristics:

Indoor unit:

  side panelling in galvanised sheet metal painted with polyester epoxy powders and polymerised in the oven at 180°C and 

a front cover that incorporates the Display, on two basic levels (LCD) and a 10” Graphic Touch Screen Windows CE. The unit 
is fully panelled but can be accessed on 3 sides since the panels can be easily removed, thereby simplifying maintenance 
and/or inspections. All routine maintenance is performed from the front of the unit. 

Outdoor unit:

  side panelling in galvanised sheet metal painted with polyester powders and polymerised in the oven at 180°C. The unit is 

totally faired and panelled and is available in RAL9002 (Grey White).

  6-pole axial fans with blades having a high degree of overlapping, combined with asynchronous motors with an external 

rotor (or synchronous with permanent magnets) and continuous modulation of the rotation speed.

Remote unit for indoor installation (attic):

 

  panelling in galvanised sheet metal painted with polyester powders and polymerised in the oven at 180°C. The unit is 

totally faired and is available in RAL9002 (Grey White).

  Radial fans with brushless motors are used, which are ideal for continuous and efficient modulation. Maximum head 

available at 200 Pa.

The components are distributed to guarantee easy access and the layout ensures optimum weight distribution on the unit's 
base.
