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). Close the radiators in rooms not in use. Do not run hot (or cold) water pointlessly. Install an energy-saving shower head, which can save up to 40 % energy. Take showers rather than baths. A bath consumes twice as much water and energy. 7.1.2 Room thermostat and settings 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. 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 room thermostat when you air the rooms. When setting the programmable thermostat timer, bear in mind days when you are absent or will be on holiday. 7.2 Recommendations The remote control is available in the following versions: Wired Radio The control panel and/or the remote control setting has a considerable influence on energy consumption. A few tips: In the room in which the room thermostat is installed, it is advised that thermostatic valve radiators are not used. If a thermostatic valve is used the valve must be fully opened. Completely closing and opening thermostatic valve radiators causes undesirable temperature fluctuations. Open and close thermostatic valves in small steps. Lower the setpoint to approx. 20°C. This will help reduce heating costs and energy consumption. Lower the set point when you air the rooms. When setting a timer programme, bear in mind days when you are absent or will be on holiday. 42 AWHP-2 MIT-IN-2 iSystem 7629848 - v05 - 28082018 8 Disposal/recycling 8 Disposal/recycling 8.1 Disposal and recycling Fig.32 Warning Removal and disposal of the heat pump must be carried out by a qualified professional in accordance with prevailing local and national regulations.
