Airflow Linkage & Fault Monitoring for Duct Purifiers: The KY265AFS220V runs directly on 220VAC mains and switches power to duct equipment such as ESP/plasma air purifiers and UV lamps only when the central AC fan is blowing. A temperature compensation probe keeps sensing consistent across seasons, while the power-supply feedback input and fault dry contact let your system detect and report equipment faults.
Engineering Highlights
01. Temperature-Compensated Sensing
A dedicated temperature compensation probe keeps airflow detection consistent at different duct temperatures, reducing false triggers in summer and winter.
02. Automatic Fan Linkage
Detects airflow from 0.5 m/s (adjustable) and switches 220VAC output to the connected device; no airflow means no output and the controller stays in standby.
03. Fault Detection & Dry Contact Output
Connects to the feedback wire of the high voltage power supply to monitor its status, and provides fault dry contact pins for BMS or external alarm signaling.
04. Remote LED Panel & Easy Service
Separate indicator board (green: power, red: fault) can be mounted on the unit housing. 30~50s self-test at power-on, and the sensor can be bypassed for maintenance.
