Infrared Heating | Heater Controller Infresco-P 4kW Controller X20114 4000W, 240V Energy-Saving Controller with PIR and Temperature Sensor 0044 (0) 1704-516 501 enquiries@united-automation.com www.united-automation.com CONTACT US: KEY FEATURES: The Infresco-P 4kW Controller is designed to optimise energy usage for Quartz Infrared Halogen Lamps. Featuring a built-in PIR sensor, this model ensures that lamps activate only when people are detected within a 5-meter range and a 100° detection angle. This energy-efficient functionality is further enhanced by a temperature sensor that disables the lamps when ambient temperatures exceed the adjustable set point between 1°C and 60°C. The microcontroller-based system integrates zero-voltage switching and a soft- start mechanism to mitigate the high inrush current typically seen with lamp activation, potentially increasing lamp life by up to 30%. The lamps remain on for a fixed duration of 5 minutes, which is reset upon detecting further movement. With easy installation and minimal maintenance, the Infresco-P 4kW Controller is a cost-effective and reliable solution for ensuring efficient heating in various applications. This product is ideal for users seeking a reliable, energy-efficient heating solution with straightforward installation and operation, backed by robust features for enhanced performance and lamp longevity. Energy Saving: Activates heat only when people are present, reducing unnecessary energy use. Extended Lamp Life: Soft- start and zero-voltage switch-off functions help increase lamp longevity by up to 30%. Temperature Sensor: Automatically inhibits lamp operation when ambient temperature exceeds the set point. Cost-Effective: Offers advanced features at a competitive price. Easy Installation: Simple setup process with minimal maintenance required. LED Indication: Blue LED for power ON and red LED for heater ON status. TECHNICAL SPECIFICATIONS Supply Voltage 230VAC ±10% @ 50/60Hz Switching Capacity 4kW Max. Detection Range 5 metres Detection Angle 100° Temperature Set Point 1 – 60°C Lamp On-time 5 Minutes (fixed) Current consumption (control circuit) 50mA Terminals 2.5mm2 Rising Clamp Operating Temperature -20 – 40°C Protection Rating IP65 Gland Diameter Max Cable Entry 2.5mm2 Enclosure Dimensions (W x L x H)(mm) 100 x 112 x 55 APPLICATIONS: The Infresco-P 4kW controller is ideal for a variety of settings, including: Outdoor Heating: Perfect for patios, terraces, and outdoor dining areas. Commercial Use: Suitable for restaurants, hospitality areas, and other commercial spaces. Industrial Environments: Can be used in warehouses, workshops, and other industrial applications where infrared heating is required.

The passive infrared sensor (PIR) in this unit detects changes in infrared energy through the Fresnel lens on its front face. The detection area and range are significantly influenced by its mounting position. The PIR detects movement of the human body as well as other heat sources similar to it. To prevent false activation, do not position the unit directly facing or in close proximity to the heater lamps. Also, avoid placing the unit near heating flues/exhausts, air conditioning units, moving trees/bushes, and reflective surfaces. Note: The PIR cannot detect a stationary human body. To ensure the proper function of the PIR sensor, avoid exposing it to rapidly changing temperatures, strong shock or vibration, or high humidity and temperature.

These regulations contain important requirements regarding the safety of electrical equipment (for International Standards refer to I.E.C/ directive IEC950). Warning! Isolate the mains supply before commencing any work on the unit. Failure to do so could result in serious injury or fatality. Cable Gland Usage o The unit is equipped with two cable glands. Ensure only one cable is fitted per gland to maintain the unit’s IP rating. o Refer to the 'Wiring Diagram' on the next page for an alternative configuration using a junction box. Mains Supply Connection o Connect the mains supply to the terminal block marked ‘LINE’: Supply LIVE to the ‘L’ terminal. Supply NEUTRAL to the ‘N’ terminal. Supply EARTH to the ‘E’ terminal. Lamp Connection o Connect the lamps to the terminal block marked ‘LOAD’: Load LIVE to the ‘L’ terminal. Load NEUTRAL to the ‘N’ terminal. Load EARTH to the ‘E’ terminal. o If connecting two lamps, wire them in parallel. Warning! Ensure all earth wires are connected to maintain earth continuity to the lamp fittings. Final Checks o Verify all wiring connections are secure. o Ensure the cable glands are tightened properly to maintain the unit's IP rating. By following these steps carefully, you can ensure the safe and efficient installation of your unit. COMMISSIONING Turn the set point temperature pre-set (VR1) fully clockwise to select ‘walk test’ mode. VR1 is located at the top of the printed circuit board as shown opposite. Replace the lid and switch on the mains supply to the unit. The controller will remain idle for 60 seconds to allow the PIR sensor to stabilise. After 60 seconds, the detection area can be walk tested to verify the PIR’s coverage. Each time the PIR detects sufficient movement, the lamps switch on for 5 seconds. Note: Each time the lamps switch off, the PIR is inhibited for 5 seconds to prevent changes in infrared energy, given off by the lamps, from causing a false activation. Once the detection area has been verified, adjust the set point temperature as required. This will automatically disable the ‘walk test’ mode. The lamp on-time is fixed at 5 minutes. Note: If the ambient temperature exceeds the set point temperature, the lamps are inhibited.

The ambient temperature may have exceeded the set point temperature. If necessary, increase the set point temperature (VR1). Check the lamps/Lamp fittings. Contact your supplier. Lamps do not switch OFF Ensure nobody enters the detection area for 5 minutes. This will allow the 5 minute on-time to expire. The PIR might be continually being re-triggered due to false activations. Mask the PIR lens and wait 5 minutes. If the lamps switch off after 5 minutes, the PIR is receiving false activations. See section ‘Installation’. Contact your supplier.
