CHAPTER 4 APPLIED OPERATION

Ă Switching between advanced PID control and ON/OFF control is carĆ
ried out by the PID/ON/OFF" parameter (expansion mode). When this
parameter is set to [ĂĂĂ
], advanced PID control is selected, and when
set to [ ], ON/OFF control is selected. Default is [ĂĂĂ ].
Ă In ON/OFF control, hysteresis is provided in the program when switchĆ
ing between ON and OFF to stabilize operation. The hysteresis width
provided during ON/OFF control is simply referred to as hysteresis."
Control output (heat) and control output (cool) functions are set in the
hysteresis (heat)" and hysteresis (cool)" parameters, respectively.
Ă In standard control (heating or cooling control), hysteresis can be set
only for the heating side.
