For situations where simplicity of control is paramount. The SET range of time controls has been designed with simplicity of programming and use in mind. The range includes an electronic time switch, a mini-programmer and a programmer, as well as an electro-mechanical programmer. All models offer 24 hour control and are deisnged to fit the British Gas Standard Wallplate used by earlier SET models and some models from the Hortsmann range. All models have LED status indicators and have easy to use rocker switches for programme selection. The On/Off times can be seen at a glance on the SET3M. Using the slider switch on the electronic models the On/Off times are shown on the large, clear display. Programmes can be manually overridden, by the thumbwheel on the SET3M and by the ADVANCE +1hr buttons on the electronic models.
