Have a 55 ton aircooled McQuay chiller. Two 15 and two 12.5 scrolls in parallel. R407c.
System has 13 fancoils with a auto bypass valve with differential controller since coil valves are two way.
We are constantly getting Low Water Temp trip on system Our water balancer says there is more than enough flow through barrel? Even at low load conditions!
Set for 36 degrees trip.Seems we mostly trip at low load conditions at nite when most of the coils are not being used.
I was wandering if this micro 2 controller has a min on time per compressor?? If so is there a chance that compressor will stay on even if its be low 45F and it's in it's min on time????? Shouldn't the micro 2 shut it down at 45F before it goes lower????
