I guess what I'm looking for is the info I need to figure out if this is something I'm going to be able (and willing) to learn in a short time. If not, we either need to pursue a different system or I need to pursue a different company. I was a full-time controls tech for several years and got burned out on it. Now I primarily do Commercial HVAC/R service work and have been enjoying that. I told this company I didn't want to do full-time control work but I guess they didn't hear me. Supermarket Racks are what I really love, but we don't do that.
