Hytronik HC038V Detached Occupancy Detector for Tri-Level (Corridor) Control

The Hytronik HC038V is a detached linear occupancy detector designed for tri-level dimming control (corridor function) in indoor environments like offices and classrooms. Operating on a 220-240VAC input, it serves as a control base that can be paired with microwave or PIR sensor heads to provide automated lighting management with high efficiency.

Core Technical Specifications:

• Load Ratings: Supports up to 400W (capacitive) or 800W (resistive) loads.
• Dimming Interface: Features a 1-10V output for dimming control.
• In-rush Current Protection: Includes a zero-crossing detection circuit to minimise in-rush current, significantly prolonging relay life.
• Standby Power: Highly efficient with a standby power consumption of less than 0.5W.

Functional Features

• Tri-Level Dimming: Manages light levels in three stages: 100% brightness during occupancy, a dimmed standby level (e.g., 10%) during a waiting period, and eventual shut-off.
• Daylight Management: Includes 24-hour daylight monitoring and a "Lux Off" function that automatically turns off lights if natural light exceeds a pre-set threshold for more than 5 minutes.
• Control Modes: Supports fully automatic operation, a semi-auto "absence detection" mode (manual-on, auto-off), and manual override via a push-switch terminal.
• Configuration: Settings are adjustable via the HRC-05 or HRC-11 remote controls, allowing for precise tuning of detection range, hold-time, and daylight thresholds.
