Energy Saving Devices

Light Controllers

Most ceiling fans are installed at locations where only lights existed before, leaving only one wall switch and one 120 Vac line available to power the fan and light. Our Ceiling Fan/Light Controller allows a ceiling fan and light to be controlled independently from one existing wall switch by using your existing light switch in a simple "OFF" and "ON" 3-stage sequence.

Wireless Devices

Functional Devices, Inc. offers many devices to provide our customers with short range EnOcean enabled wireless solutions as well as much longer-range solutions provided by combination AIC/RIB I/O boards.

EnOcean enabled wireless relay receivers in both 120 and 277 Vac models work in conjunction with many devices such as wireless wall switches and one way transmitters that are activated by the output of a BAS or Lighting controller. Look to Functional Devices to be on the cutting edge of wireless solutions in the near future with additions to our product line. Wireless occupancy sensors, two-way wireless transceivers, wireless current sensors, and current sensor/relay combination devices along with other specialty devices are just a short list of products on the horizon.

Half-Light™ Controllers

Providing independent control for multiple ballast light fixtures from a single existing wall switch, the Half-Light™ Controllers can significantly reduce a building's light output, enabling professional lighting users to cost-effectively enjoy the benefits of lighting control with just a simple toggle of their wall-based light switch. Easy to use and install, Half-Light™ Controllers from Functional Devices are fully compatible with the market's range of popular fluorescent and HID lamps and represent a simple and affordable alternative to the industry's costlier and more complicated dimming systems and components.

Evaporator Fan Controller

The Evaporator Fan Controllers are developed for use in walk-in coolers and freezers like the ones found in convenience stores, flower shops, schools, hospitals, cafeterias, etc. The fans in the evaporator boxes run at normal speed at all times, even if the thermostat is not calling for a cooling cycle. To save money, the Evaporator Fan Controllers monitor the the temperature on both the intake and exhaust of the evaporator fan unit. When the temperature of the exhaust is lower than that of the intake, the fans will run at normal speed. When the temperature of the exhaust is equal to the intake temperature however, the evaporator fan controller will reduce the speed of the fans to save energy, significantly reducing energy costs.
