The Intelliswitch 2™ digital controller is patented and designed exclusively for air curtain operation in commercial occupied spaces. It is factory-programmed/interfaced to operate with the Maxair and Zephyr air curtain models. The controller has user-friendly programming and diagnostics capabilities. All functions are supported by a microprocessor that features 16-MHz clock speed, 64 kb of program memory, 4 KB of RAM, and precisely accurate analog/digital conversion. According to the manufacturer, the availability of three standard default settings with the alternative of custom-programmed/saved entries for pinpoint control of variable volume, velocity, temperature, and timing, is a perfect solution for seasonal environmental control. It offers the flexibility of a 10-speed fan to use the least amount of energy for offsetting any external wind speed or boosting employee comfort. It is capable of efficiently running the optional onboard electric heater or hot water/steam coil as supplemental heating during open-door periods or as area spot heating when the door is closed via the Intelliswitch 2’s programming capabilities. The control comes factory-installed in an air curtain or its faceplate display can be remotely wall-mounted - both methods allow easy accessibility for maintenance via the controller’s low-voltage flexible and extendable cable connection. An optional handheld remote control is also available. Certain functions can also be linked to any facility building automation system protocol.
