I'm looking for a good resource for economizer diagnostics. I'm being trained on Commercial HVAC and unfortunately my lead techs have told me to disable them. I'm school we learned a fair bit about how they operate and the different types of sensors and controls but the issue is at least 75% of units I come across have Economizers that are not functioning. This makes it tricky for me to learn becuase I can't "play" with them. What I've been doing is look up the manual for the specific economizer and try to read about it after I leave. This frustrated me a week ago when I had a kitchen with a RTU with a cracked condenser coil and it was 55 outside and I couldn't get the Economizer opened.
