Profile: Mini Specialists Ltd specializes in providing energy saving products and controls. Our products include thermostats, humidistat, extension timers, plate-switch timers, lighting controls, soft-start timers and boiler controls. The E810 electronic thermostats are a range of vandal-resistant products designed to accurately control the set temperature in schools, public & commercial buildings even out-stations to within a degree centigrade. To prevent unauthorised adjustment, all knobs are hidden behind a cover which is secured by tamperproof screws. Along with accuracy, this measure enables energy bills to be slashed by up to 20 percent. The E321 lighting controller is designed to save energy by switching off lights when a room or space is unoccupied or where the natural lux level exceeds a pre-determined level (optional extra). Using advanced PIR elements, the unit senses movement (or the lack of movement) while its advanced opto-sensor detects the light level. This combination manages the required light level. The unit can be easily networked with the popular E818 setback thermostat.
