{"product_id":"alr-vavihsd","title":"VAViH-SD","description":"\u003cp\u003eThe Alerton BACtalk VAViH-SD controller with integrated actuator is a versatile BACnet -compliant controller, providing pressure-independent control of any single-duct variable air volume (VAV) box. It features a built-in airflow sensor, five universal inputs (AIs or BIs) and six binary outputs (BOs). As a native BACnet controller, the VAViH-SD integrates seamlessly with your BACnet system, the VAViH-SD-F includes a filter to reduce dust contamination. The BACtalk VAViH-SD contains an integral airflow sensor to provide pressure independent operation of the VAV box. Each airflow sensor is factory-calibrated at multiple velocity points. Minimum, maximum, and reheat airflows can be entered either at a Microset wall unit or an operator workstation. A technician can adjust airflow parameters in the field during balancing to compensate for slight variations in box installation and type. The direct-coupled, brushless actuator is a high-reliability, maintenance-free ON-OFF\/floating point control model manufactured by Honeywell. Its universal V-bolt clamp assembly mounts directly to the damper operating shaft. All control algorithms are factory-loaded into non-volatile flash memory and can be completely field-modified. The VAViH-SD can execute control algorithms independently of other equipment. All calibration, programming, and operator entered setup data is stored in flash memory for further assurance of stable, reliable, and independent operation.\u003c\/p\u003e","brand":"Alerton","offers":[{"title":"Default Title","offer_id":47988991820016,"sku":"ALR-VAVIHSD","price":1567.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0777\/5118\/9744\/files\/af69d4509149ce01fb4354c2302e801532045aa6.jpg?v=1779267204","url":"https:\/\/www.building-controls.com\/products\/alr-vavihsd","provider":"Building Controls \u0026 Solutions","version":"1.0","type":"link"}
