I bought two Model 619 units to help set up my dehumidifier.  The one unit displays "low" when the immediate reading is 53% and the Low is 42% and High 61%.  The manual indicates the reading should show "OK".  Should I exchange the unit?  It has been running for 48 hrs.  Other unit seems to correlate to conditions and the explanation in the manual.
