The Zipset app, when downloaded onto your iPhone 4S, 5, 5c or 5s, or iPad Mini and iPad (3G or later) will provide the convenience of wireless remote operation of the Zipset System Hand Held Controller, HHC-1R. The app allows the balancing technician with their iPhone, via the HHC, to adjust the CW or CCW positioning of the inaccessible air balancing damper. In addition, there is visual indication on the iPhone graphic that the damper actuator is moving the damper, or if not, a red indicator glows to reveal a possible open or short wiring problem. A low controller battery alert is also featured as a convenience.
