IMPORTANT CHANGE: Due to the policy set forth by Illinois as related to schools, we have converted some of our in-person classes to online classes. A link and instructions to attend the online class will be emailed to you a couple days prior. PLEASE READ ABOVE ------------------------------------------------------ ------------------------------------------------------ ------------------------------------------------------ ------------------------------------------------------ Times are changing and the current code requirements for high IEERs are driving the market to use VFDs for Staged Air Volume (SAV) in place of the traditional constant volume systems. Technicians need to know how to properly service these units. Topics covered include installation, start-up, programming, and troubleshooting. We will discuss standard RTUs, VFD controlled SAV RTUs, and economizers. We will focus on Bryant and Carrier SAV equipment in the 3 thru 25 ton range. Prerequisite: Basic HVAC service knowledge.
