ON/OFF Control Hysteresis

The following sets the hysteresis during ON/OFF control.
Up to seven types of hysteresis (palettes 1 to 7) can be
recorded. Recorded hysteresis can be recalled from
selected PID number ("P P P P L L L L n n n n 1 1 1 1 ") in the operation menu.
• Range: 0% to 50% FS
Refer to
See "ON/OFF Hysteresis Control" (p. 32) for more information
about ON/OFF control hysteresis.
When PID parameter P = 0, ON/OFF control is used.

Cooling Proportional Band

Sets the cooling proportional band when dual outputs
are selected. Up to seven types of cooling proportional
band (palettes 1 to 7) can be recorded. Recorded cooling
proportional band can be recalled from selected PID
number ("P P P P L L L L n n n n 1 1 1 1 ") in the operation menu.
• Range: 0.0 to 100.0
Refer to
See "Cooling Proportional Band Coefficient" (p. 33) for more information
about cooling proportional band.
