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 consumed electrical energy.

Scope of application

This heat pump provides:

- Heating in winter,

- The addition of electrical back-ups*, for extra heating

on the coldest days,

- Installation with boiler connection* as a supplementary

heating for the coldest days,

- Control of two heating circuits*,

- Production of domestic hot water* (provided that

combined with a DHW tank),

- 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 " Required accessory" or "Optional equipment").

for correcting the ambient temperature and

programming the heat pump.

• Anti-vibration blocks (code 523574).

• White PVC oor support (code 809532) or

Black rubber oor support (code 809536).

1.3 Specications

1 Hydraulic unit : Sound pressure level in (x)m of the device, 1.5 m of the

ground, the open eld / Outdoor unit : Sound pressure level in (x)m of the

device,middle from the ground of the height of the outdoor unit , the open eld.

2 The sound power level is a laboratory measure of the emitted sound power

but contrary to the noise level, it doesn't correspond to the measure of the felt.

3 Refrigerant R410A (as per the standard EN 378.1).

4 Factory charge of refrigerant R410A.

5 Taking into account the possible additional load of refrigeration uid R410A

(see page 27).
