Help and advice

Environmental Control Systems consist of a control unit and a range of peripheral devices such as door / window operators, curtain / blind tracks and electric adaptors that can, for example, control lighting.

Many environmental control systems can control peripheral devices through both Infra Red and Radio Frequencies. Radio Frequencies can control devices in other rooms that are out of sight. Infra red has to be pointed at a device which is in sight. Infra Red is used to control appliances such as televisions and DVD players.

Some environmental control systems, are operated with buttons, others have a touch screen, these display a range of button like images, you can then press the image for the function you wish to select. If you have limited dexterity then many environmental control systems can be operated with one or two large switches. Pressing the switch once can cause each of the buttons / images to be back lit or highlighted in turn. When the button / image you wish to select is highlighted you press the large button again. This is called scanning.
