Infresco-P 4kW The infresco-P 4kW is part of a family of controllers designed to provide energy saving Troubleshooting 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 Problem: Lamps do not switch on. 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 Solution: degrees Celsius. The microcontroller-based system incorporates zero-voltage switching and a soft-start 1) Check the LINE and LOAD wiring connections to the unit and ensure the mains function to eliminate the lamps initial high inrush current potentially increasing lamp life supply is switched on. by as much as 30%. The lamps are switched on for a fixed time period of 5 minutes. This period is reset 2) The ambient temperature may have exceeded the current set point each time the PIR detects any further movement. Installation is simple and once temperature. installed is relatively maintenance free. If necessary, increase the set point temperature (VR1). Product Features 3) Check the lamps/Lamp fittings. Significant energy saving - provides heat only when people are present Extends lamp Life Problem: Lamps do not switch off. Temperature monitor lamps inhibited when ambient temperature exceeds set point Soft-start/zero-voltage switch-off Solution: Low-cost Easy to install 1) The PIR may be continually being re-triggered due to false activations. Mask the PIR lens to effectively inhibit the PIR. If the lamps switch off approximately Typical applications are Pub Patio areas, Smoking Shelters, Restaurants, 5 minutes, the PIR is receiving false activations. See section Installation for Warehouses, Work shops. Garden Lighting information. Installation Important: Read carefully the following information before installing the unit. The passive infrared sensor (PIR) fitted in this unit detects changes of infrared energy through the Fresnel lens on the front face of the unit. The detection area and range depend significantly on its mounting position. The PIR not only detects movement of the human body, but also other heat sources similar to the human body. To prevent false activation, the unit must not be located directly facing or in close proxim ity to the heater lamps. Avoid locating the unit near to heating flues/exhausts, air condit ioning units, moving trees/bushes and reflective surfaces. To prevent malfunction of the PIR sensor, avoid subjecting it to rapidly-changing temperatures, strong shock or vibration or high humidity and temperature.
