Yearly time-switch simplifies energy saving

Hager has launched a yearly time switch that offers a simple method of saving energy through the distribution board and is easy to install and program.

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

Products that manage a building's energy consumption do not need to be complicated and the simplest and most cost-effective method is often to retrofit control to the existing electrical distribution system.

This new yearly timer brings a new level of functionality, yet it is simple to fit and program.

The four-channel timer has a large display with programming functions.

It has up to 300 programming steps that include a basic weekly program, sub programs, specific programs and additional program steps.

The resulting control can be as simple or as sophisticated as the user wants to make it.

In addition there is an input allowing an external override.

Typically the basic weekly function would run permanently unless overridden by a sub program.

The sub program lets the user define a different weekly program and the period when this program will run.

A specific program step is the next level of control and defines a specific time and date.

Finally there is a holiday option.

The output from the timer can be defined as on, off, impulse or cycle.

It also takes into account all events linked to an annual cycle, so it will, for example, calculate when Easter is in the year.

After programming, the keyboard on the timer can be locked with a PIN code.

The information can be saved onto a programming key and used to program other yearly time switches with similar control needs.
