Variable Air Volume

With 75F’s advanced algorithms and continuous feedback loops, customers can achieve the objectives that ASHRAE Guideline 36 outlines with an out-of-the-box solution for Variable Air Volume/Multi-zone AHU configurations. ASHRAE Guideline 36 and its correlated RPs (1455, 1547, 1587, 1747) provide the mechanical design community with a resource to deliver uniform, high efficiency control sequences for HVAC systems. 

75F Smart Node wireless controllers in each terminal unit collect hard-wired sensor data such as zone temperature and humidity that is wirelessly transmitted to the 75F Central Control Unit™ (CCU) for holistic load calculations and central air handler control. In addition to hydronic and electric reheaters, the Smart Node is designed to control damper actuators, parallel fans and series fans from the same device. Airflow temperature sensors deliver entering and discharge temperature data to the Smart Node, and wirelessly to the CCU.

Whether you oversee one or many locations, onsite or remote, 75F VAV with Reheat makes managing your buildings a breeze with the 75F Facilisight^® suite of web and mobile apps. Gain insight into your building’s HVAC system. View and adjust air temperatures, check system performance and create custom schedules via the portal or mobile app. Our Global Policy Editor allows you to push updates to multiple locations with one click, making your workflow far more efficient.
