Man I hate wirenuts, all hail the Wago style connectors

[@subcoolHVAC]

Yep, apparently wire nuts were hard for someone to install correctly here.

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.

Great video Subcool . Hanging barely great catch. I like the low volume guitar riffs in the background in the beginning.

[@subcoolHVAC]

Thanks, I do enjoy some electric guitar with some overdrive gain 🎸

5:12 - Kevin Malone: I always set it to 69°F.

[@BartlettTFD]

A couple of Wago connectors on the sensor cable would have prevented this problem‼️

[@subcoolHVAC]

Looking at the wire nut while screwing it on would have prevented it too 😀

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. 😅

[@subcoolHVAC]

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

[@brent562]

@@subcoolHVAC is that to be able to bypass an individual circuits call and force that load to energize?

[@subcoolHVAC]

Yes, just flip the switch to close the switch.

Rip out BS EMS system and install a normal T.stat

[@subcoolHVAC]

Whoa whoa , what about all the $ they’re saving us ? 🤣 If it was allowed I would

@@subcoolHVACThe sales people convince management they will save a ton of money. Plus it makes jobs for monitoring people. School districts are major customers.
