The Infresco P-6kW Passive Infrared Controller is part of a family of controllers designed to provide energy saving when used with quartz infrared halogen lamps or other heating and lighting products. 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 5°C and 25°C.
The microcontroller-based unit incorporates zero-voltage switching and a soft-start function to eliminate the lamps’ initial high inrush current. This can potentially increase lamp life by as much as 30%. The lamps are switched on for a user- settable time period of between 1 and 60 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.
PIR Control Case Study
Heating Solution | Workshop
Floorspace | 10m x 10m = Total 100m sq space
Heaters | 4 x Tansun Apollo A1C (6kW each). Each covering 25% of the floor space. Forming 4 ‘zones’
Controls | 4 x Infresco P-6kW Passive Infrared Controller. Installed near their respective heater. Detection range is 5 metres.
Result | Each PIR control turns ON their individual heater in their ‘zone’ – when it detects a person is present.
Each heater will remain on for 1 – 60 minutes, depending on the user setting, and then automatically turn OFF when it no longer detects movement.
This period is reset each time the PIR detects any further movement.
However, if the temperature sensor is set to 14°C and the ambient temperature is 16°C, the heaters will stay OFF – even if it detects movement.
Only the PIR controls that detect movement in their ‘zone’ will turn their heaters ON. This minimises heat waste & maximises cost savings!
