Stage-Up Inhibiting has Restricted the Enabling of a Chiller
If some form of stage-up inhibiting is active while the conditions in the system would normally cause a stage-up to occur,
this alarm occurs as a warning. The restriction of capacity this creates is normally expected and desired when using stage-
up inhibiting, the associated loss of primary flow in primary-secondary systems my cause unforeseen problems including
water flowing backwards through the decoupler line. When all forms of stage-up inhibiting are removed, the alarm
automatically clears.
