Key Protection Switch (SW101, PROTECT)
When the key protection switch is set to the ON position, the Level Key, Up and Down Keys, and Auto-tuning Key cannot be operated. In effect,
the Temperature Controller is write-protected and the set values (such as the alarm value) can be read out only. The set point, however, will not
be protected if the SP protection disable is turned ON (pin 4 of SW201).
