Hytronik HIR22 Flush-mount 1-10V Daylight Harvesting PIR Motion Sensor

The Hytronik HIR22 is a flush-mount PIR motion sensor designed for ceiling installation (requires a 70mm drill hole) with integrated daylight harvesting and 1-10V dimming control. It is engineered for precision lighting control in commercial and residential environments, and can be mounted to a height of up to 5m.

Technical Specifications

• Operating Voltage: 220-240VAC 50/60Hz.
• Load Ratings: Supports up to 800W capacitive and 1600W resistive loads.
• Detection Profile: 360° detection angle with a coverage range of 10m x 3m (Dia. X H).
• Switching: Zero-cross relay operation to minimise in-rush current and extend relay longevity.
• Wiring: Features double LN terminals for simplified loop-in and loop-out connectivity.
• Environment: IP20 rated for indoor use, operating between -20°C and +50°C.

Functional Features

• Daylight Harvesting: Automatically regulates light output based on available natural light to maintain a constant lux level.
• Control Modes: Supports fully automatic mode, semi-auto (absence detection), and manual override via a push-switch.
• Commissioning: Programming can be managed through an internal 16-channel rotary switch or via the HRC-11 infrared remote control (sold separately).
• Configurable Parameters: Adjustable detection range (10%–100%), hold-time (2s–30min), and stand-by dimming levels (10%–50%)
