Hager has launched a yearly time switch that can be retrofitted and offers a simple way of saving energy through the electricity distribution board.

Each timer can control up to four circuits, which might include lighting, heating or ventilation.

The four-channel timer has a large display with up to 300 programming functions that include a basic weekly programme as well as more sophisticated programming options and an input which allows an external override. After programming, the keyboard on the timer can be locked with a PIN code. The information can be saved on to a programming key and used to programme other yearly time switches with similar control needs.
