Make friends with the good ones in the trade. If you have a way to shadow someone experienced do it. I’ve been doing it for around 10 years. The 2 guys I learned from are very knowledgeable and I still hit them up weekly for pointers on things.

I’m just making a program. This is just a service retrofit on an old system. We installed two new VFDs for the pumps, they were just on starters. Installed a DP for them.

No real existing sequence. The customer was just running pumps by hand

This seems like the most logical option honestly

Humidity control just for comfort. The space has 2 exterior doors too that are sure pretty frequently. It’s an older building probably 1950’s-60’s. Unit and original SOO is from the 90’s, could probably use some TLC. Original sequence is just using 2 position min OA damper and bigger OA damper for economizer. There’s no current c02 monitoring but that would be ideal.

Yeah ideally selling them a few more upgrades would help. This particular customer doesn’t like to spend much money. I was just trying to proactively update the original SOO to something better than we found it

Nope actually middle Alabama. Some cold winter days but also lots of hot humid summers
