Thanks for the video. I know alot of techs that would have packed up early and not stayed to monitor. I'm sitting in a corn field watching a couple wall hangers do their thing, watching yoyr video lol.
Hey guys. Quick question, I just graduated from Brownson in SoCal and I was wondering why the EMS control board needed the control relays at all? Could it not be wired to the RTU’s control board directly? Like a thermostat could be? 😅 I can see the S/S relay for the VFD being its own deal and needs a way to open and close but the other relays? Is that to try and isolate circuits or should I go back to school lol. 😅
Congratulations, good question. The added benefit of those relays are they have an override switch (top right red switch) that the controller doesn’t have
@@subcoolHVACThe sales people convince management they will save a ton of money. Plus it makes jobs for monitoring people. School districts are major customers.
