Carrier RTU-Open Problem
Just installed 45 new RTU's that have factory install RTU_Open controllers in them. The issue I have is on some units the unit will go into Economizer Cooling mode even though the Space temp is 5 degrees below the cooling set point. I have to raise up the cooling set point 5 degrees above space temp to get it to come out of Economizer Cooling mode. When I try to open the control program in either Application Builder or SNAP it says that program was not made with either application. Have had my Carrier controls support guy looking into it, he has seen the same problem on other RTU's, but thought I'd see if anyone else has ran into this.
