Simple energy saving solutions
Time based switches such as time switches and programmers provide selectable on-off periods during the day, week and year or a combination of all to control various electrical loads. Simple and effective energy savings can be achieved by setting these devices so that the various loads are only switched on when they are actually needed, thereby saving unnecessary usage of energy. The hager range of DIN rail mounting timers include electro-mechanical time switches with an analogue display, and have 1 channel for daily or weekly programming.
These products are ideal for controlling loads such as lighting, heating and shop window displays etc. Digital timer switches have been developed with more programmable flexibility for daily, weekly and yearly timing functions where a more varied level of control is required in domestic and commercial applications. An optional Programme Key is available on some models to provide easy backup to a PC and quick re-installation of the programme.
1, 2 & 4 channel digital time switches, including the yearly EG493E programmers, can be programmed via the built-in interface or via the PC programmed software (supplied).
A print out of the programme can be produced for the project and kept in your records for future reference via the EG003. Different keys can be used to adapt the installation for different uses.
Programmes for holiday and shutdown periods can also be programmed. A double click on the programme step is enough to quickly modify the programme.
The programme can then be saved on the PC and or be transferred to the EG005 key via the EG003 interface.
Astrological time switches are programmed in weekly cycles in accordance with their geographical location. Functions include automatic change of winter and summer time making this type of switch ideal for energy savings for commercial and residential applications especially the programming for holiday periods and bank holidays.
Staircase timers provide control of lighting circuits with automatic switch off after a pre-set time. This makes them ideal for energy saving in corridor or staircase type applications, with pre-warning of switch off and double delay functions for the occupant’s safety.
A typical application example for energy saving using EG493E yearly time switches. To reduce energy and hence running costs, a four channel yearly time switch could be installed in a small office or business property. One channel could be used to control the lighting during the evenings to reduce unnecessary usage of energy.
Another channel could be used to ensure that storage heating is not used over the weekends and bank holidays when the building is unoccupied. A third channel could be used to control the external advertising or building signage during unnecessary periods e.g. between 10pm to 7am.
The final channel on the yearly timeswitch could be used to control the immersion heating function, again, to ensure that the water in the building will not be turned on during weekends and / or bank holidays. An example of potential savings from the first channel example above are shown below:
