have spent the last couple days reading Trane technical documentation on the programming of Comfort-R, not only the installer/tech manuals but the actual factory training material. I also am compiling the developer material for the control board programming to understand it better.
one thing that is not entirely clear to me is how and what interaction occurs with thermostats which control via time delay functions the activation or deactivation of Stages.
many of Comfort-R's own tricks include time relay functions in the control board. thus, I'm pondering what detriment it may be if another type of control, namely the actual startup of a stage, is handled by an intelligent thermostat?
for example, my own use of the climatouch on my XL19i is currently setup to run at least 55 minutes of Stage 1 and only then activate Stage 2 (if needed). does that negate some of the 3-minute, 7-minute, parameters for Comfort-R or are these deprecated to only being active upon Stage 2 going on-line?
