The contents of the buffer memory and those of the EEPROM can be checked.
When data is 0: The contents of the buffer memory do not match with those of the EEPROM.
• As data is being written to the EEPROM in backup mode, do not turn the power
off. If turned off, no set values are stored.
• If the set value is changed after the backup mode is changed to the buffer mode,
0 is set (mismatch). As the set value changed is not backup, select the backup
mode if necessary.
When data is 1: The contents of the buffer memory match with those of the EEPROM.
(Data write to the EEPROM is completed.)
2
For heat/cool control: Heat-side proportional band
3
In case of heat control, become RO (read only).
4
Minus (-) setting results in overlap.
