3 Description

3.1 General description

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.

4.4 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 on the house’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.

4.5 Turning on the antifreeze function

Put the heat pump into HOLIDAYS mode. ¼See chapter: "Selecting the operating mode", page 18

4 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.

7.2 Recommendations

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.

The remote control is available in the following versions:

4 Wire

4 Radio

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.
