Lighting represents the primary source of electricity consumption in U.S. commercial buildings, and that means digital timers can be a company’s best friend — turning out the lights, saving money and boosting productivity in both commercial and private spaces.

Intermatic offers a series of electronic controls for interior and exterior lighting that can be easily customized and programmed to any facility’s specific lighting needs, from simple on-and-off 24/7 scheduling with occupancy sensor overrides to complex year-round building energy management systems integration.

Intermatic’s ET90000 series of digital timers can, for instance, be programmed with over 2000 events, plus 99 holidays. The ET90000 series also offers USB ports, allowing quick and efficient transfer of schedules from one controller to another, as well as a backup flash drive of settings and schedules. Automatic Daylight Savings Time adjustment is another key feature, freeing maintenance staff from the hassle of lighting clock adjustment at least twice per year.

Many school districts around the country are catching on. Bob Gruber, for instance, Maintenance and Operations Supervisor for the Carmel Unified School District in California, said Carmel’s integration of Intermatic ET90000 lighting controls with the district’s building automation system covering nine sites and spread over 600 square miles has saved the organization and estimated 80-100 maintenance hours annually.

Similarly, in Charlotte, North Carolina, Christopher Mueller, Electrical Supervisor for the Charlotte-Mecklenburg schools, calculates that turning to Intermatic digital timers for exterior lighting has not only saved the district an estimated $4000 in maintenance calls, but that “students, teachers and staff have an increased feeling of safety and security now that the lighting remains constant throughout school campus areas.”

In Denver, Jim Faes, Director of Sustainability for the Denver Public School System, said faulty exterior light sensors at his 185 district schools used to result in up to 200 calls to maintenance per month. Denver installed the ET90000 line of controls and Faes now reports that maintenance calls for exterior light controls have dropped almost to zero, while he estimates the district is saving at least $180 per year per school in energy costs, which adds up to nearly $30,000 annually.

On the commercial side, timers can also be a huge help to the bottom line. Kirk Cashmore runs Cashmore’s Produce & Ponics in Northern Illinois, a hydroponic produce (lettuce, mostly) farmer. He relies on Intermatic digital timers to turn the lights and fans of his indoor farm off and on on a schedule that maximizes production. “The dependability and the livelihood of this whole operation is all based on that timer,” Cashmore says. “If I come in and the lights aren’t on or the fans aren’t on, I will have real heat buildup problems and or real growth stunt problems. I run those lights 16 hours per day, 7 days per week, so it’s very important to have a quality timer.”
