I need help understanding these things guys.
When I find myself at an airhandler with floating point actuators (24v) what should I look for as far as my meter goes? The largest part of the actuators I deal with are 2-10dcv signal and 24ac power, no problem in the least, but I simply do not understand the concept of floating point. From common to "open" I get the exact same voltage as from common to "close"
Can anyone explain it or just share a link?
The one today was a Belimo lr24-us I think but thats just from memory. I don't want you guys to troubleshoot it for me, just help me understand how FP controls get told what to do.....lol
