I have a customer site with a JCI FX controller bringing in points from a KMC controller via BACnet. Customer would like to lower the setpoint. The KMC controller has a range on the KMD stat which I thought I would lower. Because the point comes across as a 'read only' point, it appears that I cannot adjust the analog variable point. Is it possible that I can change the point so that FX controller will write to the AV on the KMC controller?
