Infresco 6KW PIR Soft-Start Controller P-6kW

The infresco-P 6kW is part of a family of controllers that is designed to provide energy saving when used with Quartz Infrared Halogen Lamps. The unit has a built in PIR sensor allowing the lamps to automatically switch on only when people are present. In addition to the PIR, a temperature sensor monitors the outside temperature and inhibits the lamps when the temperature exceeds a pre-determined set point of between 1 and 40 degrees Celsius. Additional features include a ’walk test’ facility and a sensitivity control which were not fitted to the 4kW version.
The microcontroller-based system incorporates Zero-Voltage switching and a Soft-Start function to eliminate the lamps’ initial high inrush current – potentially increasing lamp life by as much as 30%. The lamps are switched on for a fixed time period of 5 minutes. This period is reset each time the PIR detects any further movement. Once installed is relatively maintenance free.
