"What you posted is when the Refer is in a FAULT Mode. Norcold calls it a BOS(Back up/Operating/System). This allows the refer to still function when you have a fault with the Thermister or controls. A correct functioning refer will run until the Tstat is satisfied, then shut off. Doug"
I got that from the Norcold NX service manual
http://bryantrv.com/docs2/docs/norcoldnxseries.pdfEDIT-- I read that wrong. Page 13 indicates that BOS (Table 1) can be adjusted by using the Temp Sets in Table 2.
ISTR that Table 2 was elsewhere and it said it uses the Thermistor, so that wouldn't work if the thermistor is bad so it has to be in BOS.
Can't find that, so I must have been mixed up.
