4 Description
4.1
General description
AWHP-2 MIT-IN-2 iSystem
The AWHP-2 MIT-IN-2 iSystem heat pump is composed of two elements:
4
The outside unit handles energy production in hot or cold mode.
4
The inside module handles 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.

Installation shutdown
If the central heating system is not used for a long period, we recommend switching the appliance off.
4
To stop the inside module, use the J/K ON/OFF switch and cut the power supply to the home’s junction box.
4
To shut down the outside module, switch off the power supply on the junction box inside the house.
CAUTION
Antifreeze protection is no longer guaranteed automatically if the mains supply is switched off.

Advice on setting the room thermostat correctly
7.1.1.
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.
7.1.2.
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.

AWHP-2 MIT-IN-2 iSystem 7. Energy savings
The setting of the control panel and/or of the remote control has a considerable influence on energy consumption.
A few tips
:
4
In the room in which the room thermostat is installed, it’s advised not to use thermostatic valve radiators. If a thermostatic valve is used the valve must be fully opened.
4
Completely closing and opening thermostatic valve radiators causes undesirable temperature fluctuations. Open and close thermostatic valves in small steps.
4
Lower the temperature to around 20°C. This reduces heating costs and energy consumption.
4
Lower the temperature when you air the rooms.
4
When setting a time schedule , bear days when you are absent and holidays in mind.

The following provisions are not exclusive of the buyer being able benefit from the legal provisions applicable regarding hidden defects in the buyer’s country.
Starting from the purchase date shown on the original installer’s invoice, your appliance has a contractual guarantee against any manufacturing defect.
The length of the guarantee is mentioned in the price catalogue.
The manufacturer is not liable for any improper use of the appliance or failure to maintain or install the unit correctly (the user shall take care to ensure that the system is installed by a qualified engineer).
In particular, the manufacturer shall not be held responsible for any damage, loss or injury caused by installations which do not comply with the following:
4 applicable local laws and regulations,
4 specific requirements relating to the installation, such as national and/or local regulations,
4 the manufacturer’s instructions, in particular those relating to the regular maintenance of the unit,
4 the rules of the profession.
The warranty is limited to the exchange or repair of such parts as have been recognised to be faulty by our technical department and does not cover labour, travel and carriage costs.
The warranty shall not apply to the replacement or repair of parts damaged by normal wear and tear, negligence, repairs by unqualified parties, faulty or insufficient monitoring and maintenance, faulty power supply or the use of unsuitable fuel.
Sub-assemblies such as motors, pumps, electric valves etc. are guaranteed only if they have never been dismantled.
The legislation laid down by european directive 99/44/EEC, transposed by legislative decree No. 24 of 2 February 2002 published in O.J. No. 57 of 8 March 2002, continues to apply.
