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.

- Installation with boiler connection* as a

supplementary heating for the coldest days.

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

on the coldest days.

- Cooling in summer* (for oor heating-cooling system

or fan-convectors).

1.5 Operating principle

The heat pump transmits the energy contained in the

surrounding air into the dwelling to be heated.

The heat pump consists of four main elements, in which

a refrigerant  uid (R410A) circulates.

- In the evaporator (ref. 13,  gure 6, page 9) :

The energy is taken from the surrounding air and is

transmitted to the refrigerant. Because it has a low

boiling point, it changes from the liquid state to the

vapour state, even in cold weather (down to -15 °C

outdoor temperature).

- In the compressor (ref. 10,  gure 6, page 9) :

The vaporised refrigerant brought to high pressure

and takes on more calories.

- In the condenser (ref. 15,  gure 7) :

The energy in the refrigerant is transmitted to the

heating circuit. The refrigerant returns to liquid state.

- In the expansion valve (ref. 9,  gure 6, page 9) :

The lique ed refrigerant is brought back to low pressure

and returns to its initial temperature and pressure.

The heat pump is equipped with a controller, which

controls the room temperature based on the outdoor

temperature measurement and governed by the

temperature control. The room thermostat (option)

provides a corrective action for the temperature control.

The hydraulic unit can be optionally  tted with an

electrical back-up system or boiler connection which

starts up in order to provide addtional heating during the

coldest periods.

23 - Water return sensor.

• Regulation functions

- The heating circuit's initial temperature is controlled by

the temperature control.

- The power of the outdoor unit is modulated according

to  ow heating temperature via the "inverter"

compressor.

- Control of the electrical back-up heating (option).

- The daily timer program enables you to de ne

the periods for comfortable or reduced ambient

temperature.

- Summer/winter mode switchover is automatic.

- Control of the supplementary boiler* (option).

- The room thermostat (option)*: provides a corrective

action for the temperature control.

- Control of a second heating circuit*.

- Domestic hot water: Heating time programme, control

of the operation of the DHW circulation pump.

- Managing the cooling*.

- Control of swimming pool heating*.

* If the heat pump is equipped with optional equipment and the

associated kits.

• Protection functions

- Anti-legionella cycle for domestic hot water.

- Anti-corrosion protection with titanium anode (ACI).

- Frost protection: Frost protection cuts in if the low-

temperature point of the heating circuit falls below 5 °C

(provided that the heat pump's electrical power supply

is not interrupted).
