Frymaster H55 Series Technical Reference Manual page 30

The setting for each button is between 0 and 9, with 0
disabling the feature. A 9 provides the highest sensitivity
or most pronounced change. The correct sensitivity for a
product is based on its density, the setpoint and customer
requirements. McDonald's-specifi c settings are the fac-
tory default in their controllers.
Rate of Rise
If the controller sees a temperature increase (Rate of
Rise) > 5°F in two seconds it will lock out the controller
for 20-30 seconds to self test.
Recovery
The recovery check is a diagnostic tool, which measures
the time required for the fryer to raise the temperature of
the oil 50°F, between 250°F and 300°F. The measure is
taken each time the oil drops below 180°F.
A standard HE gas fryer should achieve the 50-degree
rise in 2:25. Electric fryers recover in 1:40. The M2000
does not lock out on recovery failures. The result of the
most recent recovery check is displayed when you enter
the code 1652 on the CMIII.5 or the M2000.
