First I'm glad to have found a group of guys and gals that enjoy controls as much as I do. I hope to be helpful in the future. Very brief background. I worked with ALC for 2 different contractors for a total of 12 years with the product. Last year I made a move and am working with the Talon line of controls.
In the recent cold weather we have had several jobs that have frozen up coils. Not to anyones surprise every one of them have been on jobs that we are integrating the RTU's. I really think the owners are getting the raw end of the integration deal, at least in my cases. Here's why. In my experience the equipment suppliers tend to supply, but not want to control or deal with the controls. They have overworked techs that have to learn many different equipment types and different control systems. It takes YEARS to get good at one system, let alone 3 or 4. As you guys know we are limited on what we can do though whatever interface we are provided from the equipment manufacture. I'm getting tired of telling the customers that I monitor but don't control, and ill try to set up an alarm to warn them before it happens again.
What if anything do you guys do? Maybe it is as simple as having good equipment reps. Now I need to go to a meeting in the morning for another frozen coil..... just getting sick of being dragged thought the mud for other contractors not doing their job.
