• Program Start
The simple program function can be reset/started with the related information setting. The setting
can be accepted in both setup area 0 and setup area 1. An operation error will occur if program
start has been set in the event input.
• Automatic Filter Adjustment
Select executing or canceling automatic filter adjustment with the related information setting. This
command can be accepted in setup area 0 only.
An operation error will occur in the following situations.
• When the RUN/STOP parameter is set to "stop."
• When the command is executed in "setup area 1."
• When ON/OFF control is being used.
• When the Standard or Heating/Cooling parameter is set to heating/cooling.
• When the Auto/Manual parameter is set to manual.

• Setting Areas
Control operation is executed in setting area 0. In this state, you can perform operations that are
permitted only during control or those that cause no problems even if control is in progress. These
operations include reading PVs, writing SPs, and changing RUN/STOP status.
Setting area 0, however, prohibits operations that affect control, including writing data at the initial
setting level. (Reading setting data is always allowed.)
In setting area 1, control operation is stopped. In this state, you can perform operations that are
not allowed in setting area 0. These operations include writing data at the initial setting level.
At power-ON, the Digital Controller is set in setting area 0. To move to setting area 1, use the
"move-to-setting area 1" command. To return to setting area 0, turn the power OFF and ON again,
or use the "software reset" command.
