4 Description of the product

4.1 General description

The ALEZIO EVOLUTION heat pump comprises:

An outdoor unit for energy production in heating mode only when it is
combined with an uninsulated indoor module.
A reversible outdoor unit for energy production in heating or cooling
mode when it is combined with an insulated indoor module.
An indoor module with a control panel to handle the heat exchange be
tween the R410A fluid and the hydraulic circuit.

Both units are connected by means of refrigeration and electrical connec
tions.

The system offers the following advantages:

The heating circuit is housed in the insulated volume within the home.
Thanks to the DC inverter system, the heat pump modulates its output
to adapt to the needs of the home.
The control panel uses the outside sensor to adjust the temperature of
the heating circuit according to the outside temperature.

4.2

Operating principle

4.2.1 Circulation pump

Note
The benchmark for the most efficient circulators is EEI ≤ 0.20.

4.2.2 Hybrid operating mode

Note
The hybrid operating mode is only available for appliances with
hydraulic back-up.

The appliance offers a choice between several hybrid operating modes.
The modes available offer either optimised energy consumption according
to energy cost, or optimised energy consumption according to primary en
ergy consumption. Both hybrid operating modes are available via the pa
rameter .

In optimised primary energy consumption mode, the control system
chooses the generator that consumes the least primary energy.
In optimised energy cost mode, the control system chooses the cheap
est generator according to the coefficient of performance of the heat
pump and according to energy cost.

7 Maintenance

7.1 General instructions

Maintenance operations are important for the following reasons:

To guarantee optimum performance.
To extend the life of the equipment.
To provide an installation which offers the customer optimum comfort
over time.

Caution
An annual service of the heat pump is mandatory.

7.2

Maintenance instructions

1. Check the hydraulic pressure in the installation.

Note
If the water pressure is lower than 1 bar, more water should be
added. If necessary, top up the water level in the heating system
(recommended hydraulic pressure between 1.5 and 2.0 bar, or be
tween 0.15 and 0.2 MPa)..

2. Carry out a visual check for any water leaks.

3. Open and close the radiator valves several times a year.
This helps to prevent the valves from seizing up.

4. Clean the outside of the heat pump using a damp cloth and a mild
detergent.

Caution
Only qualified professionals are permitted to clean the inside of
the heat pump.

7.3

Topping up the installation with water

If necessary, top up the water level in the heating system (recommended
hydraulic pressure between 1.5 and 2 bar, or between 0.15 and 0.2 MPa).

1. Open the valves on all radiators connected to the heating system.

2. Set the room thermostat to as low a temperature as possible.

3. Put the heat pump in shut-down/frost protection mode.

4. Open the fill valve.

5. Close the fill valve when the pressure gauge shows a pressure of

1.5 bar (0.15 MPa).

6. Put the heat pump in heating mode.

7. When the pump has stopped, vent again and top up the water pres
sure.

Note
Filling and venting the installation twice a year should be sufficient
to obtain an adequate hydraulic pressure. If it is often necessary
to top up the installation with water, contact your installer.

7.4

Venting the heating system

It is essential that you vent any air in the domestic hot water tank, the
pipes and the taps to prevent the annoying noises likely to be produced
during heating or when drawing off water.

7.4.1 Manual venting

1. Open the valves on all radiators connected to the heating system.

2. Put the heat pump in shut-down/frost protection mode.

Fig.24 Beware of water leaks

AD-0001507-A

7 Maintenance

28 AWHP-2 MIV-3 7611973 - v04 - 07032016

3. Vent the underfloor heating circuits and the radiators. First vent the
lower floors A and then the upper floors B.

Note
The heating pump stops 5 minutes after selection of the shut­down/frost protection mode. If the outside temperature is lower
than 3°C, the heating pump continues to run.

7.4.2

Automatic venting

If the parameter is set to 0, the heat pump runs an automatic vent
ing cycle when it is switched on.
If the parameter is set to 1, a domestic hot water tank is connected.
Automatic venting starts up only if the measured domestic hot water

temperature is lower than 25°C.
Automatic venting takes approximately one minute. It is possible to man
ually extend automatic venting to more than one minute.

1. When powering up, the word flashes. Press the key.
An automatic venting cycle begins. The word stops flashing.

2. Press the key to stop the venting cycle.

Caution
After venting, check whether the pressure in the installation is still
sufficient. Add more water to the installation if necessary.

10 Environmental

10.1 Energy savings

Tips on saving energy:

Do not block ventilation outlets.
Do not cover the radiators. Do not hang curtains in front of the radiators.
Install reflective panels behind the radiators to prevent heat losses.
Insulate the pipes in rooms that are not heated (cellars and lofts).
Turn off the radiators in rooms not being used.
Do not run hot (or cold) water pointlessly.
Install a water-saving shower head to save up to 40% energy.
Take showers rather than baths. A bath consumes twice as much water
and energy.

10.2

Room thermostat and settings

Various models of room thermostat are available. The type of thermostat
used and the parameter selected impact total energy consumption.

A modulating regulator, which may be combined with thermostatic
valves, is eco-friendly in terms of energy and offers an excellent level of
comfort. This combination allows you to set the temperature separately
for each room. However, do not install thermostatic radiator valves in the
room in which the room thermostat is located.
Complete opening and closing of the thermostatic radiator valves cau
ses undesirable variations in temperature. Therefore, these must be
opened/closed progressively.
Set the room thermostat to a temperature of approximately 20°C to re
duce heating costs and energy consumption.
Lower the thermostat setting to approximately 16°C at night or when you
are not at home. This reduces heating costs and energy consumption.
Lower the thermostat setting well before airing the rooms.
Set the water temperature to a lower level in summer than in winter (e.g.
60°C and 80°C respectively) when an ON/OFF thermostat
is used.
When clock thermostats and programmable thermostats are to be set,
do not forget to take any holidays and days when no one is at home into
account.
