Introduction
The infresco-P 4kW is part of a family of controllers designed to provide energy saving when used with Quartz Infrared
Halogen Lamps. The ‘P’ model 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°C and 60°C.
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. Installation of the unit is simple
and once installed is relatively maintenance-free
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 proximity to the heater lamps. Avoid
locating the unit near to heating flues/exhausts, air conditioning units, moving trees/bushes and reflective surfaces.
Note: The PIR cannot detect the presence of a human body that is not moving.
To prevent malfunction of the PIR sensor, avoid subjecting it to rapidly-changing temperatures, strong shock or vibration
or high humidity and temperature.
