The contents of IR 001 is compared to FFFF to
confirm that the Temperature Control has com-
pleted initialization processing.
If the process value (contents of IR 001) is not
FFFF, IR 01600 is turned ON to indicate that
initialization has been completed.
If the leftmost four bits of IR 001 are 1110 (E),
IR 01715 is turned ON to signal an error.
A comparison is made to EE01 to see if a set-
ting range error has occurred.
If the process value is EE01, IR 01701 is
turned ON to signal a setting range error.
A comparison is made to E400 to see if an in-
put sensor error has occurred.
If the process value is E400, IR 01700 is
turned ON to signal an input sensor error.
If neither a setting range error nor an input
sensor error has occurred, IR 01702 is turned
ON to signal other errors.

If IR 01800 is OFF, the contents of DM 0000
will be written as the set point to IR 100.
If IR 01800 is ON, CCCC will be written to IR
100.
The contents of IR 001 is written to DM 0001
as the process value.
If IR 01701 is ON, the correct set point value
data must be set.
