75F VAV with Reheat™ reduces install cost, improves energy efficiency, and delivers remote control and diagnostic capabilities to Variable Air Volume (VAV) zone controls systems. Where traditional VAV systems can be costly and inefficient, 75F has encapsulated newer ASHRAE-recommended advanced VAV control sequences. This application modernizes and acknowledges today’s fully modulating RTUs and AHUs. The complete VAV system is wirelessly connected and works out-of-the-box with zero programming required.
75F® Smart VAV with Reheat™ is a full-stack solution with components that include sensors connecting to 75F Athena for cloud analysis, a 75F Central Control Unit (CCU) as a supervisor with built-in wall interface, 75F Smart Nodes as terminal equipment controllers, third-party units with actuators or 75F Smart Dampers, and Facilisight, 75F’s building intelligence suite of web and mobile apps for secure remote monitoring and control.
75F’s sensors connect to wireless controllers called Smart Nodes placed in each zone, capturing thousands of data points a minute and millions of data points daily on temperature and humidity throughout the building envelope. Via a 900 MHz wireless mesh network, these controllers upload to 75F Athena and create a dynamic thermal model of your building. The 75F system anticipates heat loads and predictively and proactively controls the temperature and air volume in each zone.
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 VAV with Reheat allows buildings to maintain zone temperature with the warmest possible air at the lowest possible pressure, so equipment and energy consumption is minimized. Supply air temperature and fan speeds are continuously monitored and controlled based on zone loads to achieve the best possible thermal comfort and energy efficiency. ASHRAE-recommended Guideline 36 sequences are pre-configured, while always-on cloud connectivity means 75F can push sequence upgrades and software improvements as needed. Together this means best-in-class comfort and efficiency in a VAV application.
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.

Todd Westby, CEO and President of TurnKey Corrections and Three Square Market, was looking for a high tech system with cloud computing for their HVAC system. Todd was referred to 75F and was head-over-heels for the features that 75F offered. We installed VAV with Reheat in their 50,000 square foot office. Watch the video to learn out more.
