3 Description

3.1 General description

The ALEZIO heat pump comprises:

4 An outside module for energy production in hot mode only when

it is combined with an uninsulated inside module.

4 A reversible outside module for energy production in hot or cold

mode when it is combined with an insulated inside module

4 An inside module with a control panel to handle the thermal

exchange between the R410A fluid and the hydraulic circuit

The two units are connected by means of refrigeration and electrical connections.

The system offers the following advantages:

4 The heating circuit is housed in the insulated volume within the

home. There is no danger of the pipes freezing.

4 Thanks to the DC inverter system, the heat pump modulates its

output to adapt to the needs of the home.

4 The control panel uses the outside temperature sensor to adjust

the temperature of the heating circuit according to the outside temperature.

4.3.5. Hybrid operating mode

CAUTION

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 energy consumption. Both hybrid operating modes are available via parameter U1. 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 cheapest generator according to the coefficient of performance of the heat pump and according to energy cost.

To access the parameters:

Press the ¿ key 3 times.

The symbol $ flashes. Press the key ® to enter the "Installer" menu.

3. Use the + and - keys to switch from one parameter to another.

4. Use the + and - keys to change the parameter value.

CAUTION

4 An annual inspection is compulsory.

4 We recommend taking out a maintenance contract.

4 Maintenance operations must be done by a qualified

engineer.

4 Only original spare parts must be used.

4 Make certain that the flues and chimneys are

connected, in good condition and not blocked.

4 Do not modify nor block the condensate outlet(s).

4 If a neutralisation system is installed, follow the

instructions delivered with the neutralisation system for cleaning and servicing of this system.

AWHP MIV-II

5.2 Periodic checks

4 Check the water pressure in the installation. If the water pressure

is too low, add more water to the installation. ¼See chapter: "Top up the installation with water", page

22.

4 Carry out a visual check for the presence of any water leaks.

4 Open and close the radiator valves several times a year (this

prevents the valves from seizing up).

5.3 Top up the installation with water

5. Checking and maintenance

CAUTION

Only a qualified professional is permitted to clean the inside of the heat pump.

The water pressure in the installation must be between 1,5 and 2 bar. Add water to the installation if necessary:

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 shutdown/frost protection mode. "Changing the operating mode", page 18

4. Open the filling valve .

5. Close the filling valve when the pressure gauge shows a pressure

of 1,5 bar.

6. Put the heat pump into HEATING mode. "Changing the operating mode", page 18

7. When the pump has stopped, bleed again and top up the water

pressure.

8. Filling and bleeding the installation 2 times 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 fitter.

5.4 Bleeding the heating system

It is essential that you bleed any air in the calorifier, the conduits or the taps to prevent the annoying noises likely to be produced during heating or when tapping water.

5.4.1. Manual venting

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

2. Put the heat pump in shutdown/frost protection mode. "Changing the operating mode", page 18

3. Vent the underfloor heating circuits and the radiators. First vent

the lower floors A and then the upper floors Z.

5.4.2. Automatic venting

The heat pump runs an automatic venting cycle when it is powered up. Automatic venting takes approximately one minute.

If a DHW tank is connected to the heat pump: Automatic venting starts up only if the measured DHW temperature is lower than 25°C.

It is possible to extend automatic venting manually to run for more than one minute:

1. The word SERVICE flashes when powering up. Press

the SERVICE key. a venting cycle begins. The word SERVICE stops flashing .

2. Press the SERVICE key to stop the venting cycle.

¼Consult the installer for more detailed information.

WARNING

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

AWHP MIV-II 6. Troubleshooting

Problem Probable causes Solution

The central heating pipe connections are too tight.

There is air in the heating pipes.

Clicking in the central heating pipes

Contact the fitter.

4 It is essential that you bleed any air in the calorifier, the

conduits or the taps to prevent the annoying noises likely to be produced during heating or when tapping water.

¼See chapter: "Bleeding the heating system", page 22

Significant water leak underneath or in the vicinity of the heat pump

The water is circulating too quickly in the central heating system.

The pipes on the heat pump or the central heating are damaged.

Contact the fitter.

This chapter contains:

4 Energy-saving advice

4 Advice on setting the room thermostat correctly

8.1.1. Energy-saving advice

4 Do not block ventilation outlets.

4 Install reflective panels behind the radiators to prevent heat

losses.

4 Do not cover the radiators. Do not hang curtains in front of the

radiators.

4 Insulate the pipes in rooms that are not heated (cellars and lofts).

4 Close the radiators in rooms not in use.

4 Do not run hot (or cold) water pointlessly.

4 Install a water-saving shower head to save up to 40 % energy.

4 Take showers rather than baths. A bath consumes twice as much

water and energy.

8.1.2. Room thermostat and settings

4 A modulating thermostat, possibly in combination with

thermostatic valve radiators, saves energy and offers considerable comfort. This combination allows you to set the temperature on each flow. In the room in which the room thermostat is installed, do not fit thermostatic valve radiators.

4 Lower the thermostat to approximately 16°C at night or when you

are absent. This reduces heating costs and energy consumption.

4 Lower the room thermostat when you air the rooms.

4 When setting an hourly programmable thermostat, keep in mind

the days you are absent or on vacation.
