* In a memory error (RAM error) or initial state (until the control starts to look for the process value after the power is turned ON),
no commands will be accepted, and no response will be returned.
* When writing is carried out when a memory error (RAM error) has occurred, writing to EEPROM is not carried out, and processing
ends in "normal completion." Reading is as normal.

* Overflow: Set 1 when the heater current value is greater than 55.0 A.
* Display hold: Set 1 when the control output ON time is less than 190 ms. The previous heater current value is held.
