I have this CGAFC60 that has 12 fans and 6 VFDs. 1 VFD feeds two fans. My problem is half the fans are not being called for from the Tracer panel and the fans that run seem to only run half speed. I have no communication with the Tracer its stand alone and no communication tool. I知 going back today I知 sure there is a thermistor on the liquid line maybe its loose or not reading correctly We work at many sights for this client and just recently expanded servicing more of there buildings. This unit is a special order not standard. Both liquid lines are running hot. I know Its a 2004 Tracer MP panel. I just wondered if anybody has experienced this. Thank You.
