Atlantic alfea extensa Series - Description of the unit; 1.1 Package; 1.2 Definitions

1 Description of the unit
1.1 Package
• 1 package: outdoor unit.
• 1 package: hydraulic unit and outdoor sensor.
1.2 Denitions
- Split: The heat pump consists of two elements
(an outdoor unit for outdoor and a hydraulic unit for
inside the dwelling).
- Air/water: The surrounding air is the energy source.
This energy is transmitted to the water in the heating
circuit by the heat pump.
- Inverter: the fan and compressor speeds are
modulated according to the heating requirements.
This technology enables you to save on energy and
operate on a single-phase power supply, whatever the
heat pump's output, by avoiding heavy intensities on
start-up.
- COP (coefcient of performance): this is the relationship
between the energy transmitted to the heating circuit
and electrical energy consumed.

Scope of application
This heat pump provides:
- Heating in winter,
- Control of two heating circuits*,
- Production of domestic hot water* (provided that
combined with a DHW tank),
- Installation with boiler connection* as a
supplementary heating for the coldest days,
or
- the addition of electrical back-ups*, for extra heating
on the coldest days,
- Cooling in summer* (for oor heating-cooling system
or fan-convectors),
- Heating the swimming pool*.
* : These options require the use of additional kits
(see para "Optional equipment").
