4 Description

4.1 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.

7.1 Energy savings

This chapter contains:

4 Energy-saving advice

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.

7.1.2. 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.

7.2 Recommendations

The remote control is available in the following versions:

4 Wire

4 Radio

7. Energy savings

AWHP-2 MIT-IN-2 iSystem

10/06/2015 - 7616372-001-05

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.
