Hi my name is Javier Borges I am from PR right now I am installing 20 Tons Chilled water system using 4 Trane 4TTZ060 condensing units and 2 10 tons plate HX. Right now I have trouble deciding which DDC Controls to use should I use Trane Controls (++++++++++ Expensive) or my trusted control supplier which supplies Trend Controls. For those of you that do not know these trane units have two compressors inside of them and requiere a special wiring harness to connect them to any control either Trane or Trend. Please reccommend thanks.
