I am a very recent adapter of OS and have in fact not been able to complete install and place it into use. Note I am using two expansion boards as well and have 40 stations.
The issue I am having is a Dead Channel 2 on the OS main unit. I’ve isolated the main unit, placed it on the bench and indeed verified it’s not a simply Mfg solder issue (Not a DIY). All other channles work and channel 2 LCD indicates it is on when activated (using manaual mode) but no 24VAC on the output pin.
#1 Is there a common failure mode
#2 Is there a common user-induced causality
thanks In advance!
