This sets the integral time. It is valid only when SW203-1 is set to OFF (i.e., PID
control).
This value is reflected even when auto-tuning (AT) is executed.

Settings can be made within the following range:
Sensor measuring range lower limit to (SP upper limit – 1 digit)
When powering up or starting, the lower limit of the measuring range for sen-
sors set by the rear-panel SW202 (sensor type) is set automatically. For exam-
ple, if SW202 is set to "2," the thermocouple type is set to "–200." However, the
SP lower limit will not be changed if the current SV lies inside the sensor mea-
suring range.

Settings can be made within the following range:
(SP limit + 1 digit) to sensor measuring range upper limit
When powering up or starting, the upper limit of the measuring range for sen-
sors set by the rear-panel SW202 (sensor type) is set automatically. For exam-
ple, if SW202 is set to "2," the thermocouple type is set to "1300." However, the
SP upper limit will not be changed if the current SV lies inside the sensor mea-
suring range.

This sets the cooling output dead band, and it is valid when SW203-1 (PID con-
trol) is OFF.
The relation between the dead band and the set temperature is as shown in the
illustration below.
