While Logging data this morning I found that on my YCWS System#2 the oil level was super low. I don't have any alarms as of yet though. System#2 was not running due to System#1 being able to handle the low demand.
Typically the bottom sight glass is full and the upper sight glass is half full or less. There are no signs of leaks anywhere.
Could this be normal, perhaps when this system comes online the oil will re-appear?
