(1) Used to specify as unused the channels where temperature control will not be
performed and temperature sensors will not be connected.
(2) For the channels set as unused, the "ALM" LED will not be lit if a temperature
sensor is not connected.
(3) Turning on Default setting registration start command (Yn9) clears the unused
channel setting. When there are channels where temperature control is not
performed and temperature sensors are not connected, make unused channel
setting after completion of default setting registration.

(1) This command reads PID constants from E
Setting 1 (With command) to this command reads values in E
following buffer memories.
Buffer memory address name
Proportional band (P) setting
Integral time (I) setting
Derivative time (D) setting
Loop disconnection detection judgment
time
(2) This function is the most suitable for use when you want to use the initial settings
of the utility and the PID constants backed up on E
(3) When 1 (With command) is set to this command, do not perform the setting value

change, E PROM backup, and default setting registration.
(4) When executing auto tuning, set 0 (Without command) to this command.
If auto tuning is executed while setting 1 (With command) to the command, even if
internal processing of auto tuning is completed and PID constant is stored, Auto
tuning status (Xn4 to Xn7) does not turn OFF and auto tuning is not completed.
