Older Liebert fh199a-c00 Humidifier's driving me nuts.
I have three Liebert fh199a-c00 units in a electronics room and each one is killing me with there low humidity alarms. Each is set at 40% with a 5%diff thats the max diff it will let you enter on two of the units the other unit was updated with a newer logic board and you can adjust the diff higher.
Each time they alarm I go and check them and find them either in alarm or they reached the thresh hold in that 5%.and reset themselves. I dont understand it, theres water in the pans and the lights are on. Do these lights lose there heating ability?(didnt think so) there freakin hot! Are these units a pain in the butt all together with humidity issues? I wish I could adjust that diff a little wider. Any tips on these would be great. I did find the one pan empty with the pan limit tripped. I reset it and ran it through its operation, ok. Am I understanding that when a call for humidity the water is timed on for 80 seconds and it does that every 10minutes??? Sometimes i see it come on for 10 seconds then shut off. I'm a virgin at these so any help would be appretiated. Thanks.
