Integration time setting
When there is a certain deviation, the time that the combined action and the
proportional action work together is the integration time.

This function is not used if the integration time is set to 0.
The integration time setting is too short. The correction action for
interference is weak, but it is not easy to produce overshoot.
Derivative time setting
The time required for the differential action and the proportional control of the deviation
on the slope is the differential time.

This function can't be used if the integration time is set to 0.
Control cycle setting
Under the control of the relay or SSR output, the output is kept for a fixed amount of
time (the percentage of the manipulated variable during the control period) remains off.
When the output ON/OFF changes to the proportional period control within the preset
period. The SSR control output responds faster than the relay output, so the period
required for control is shorter and easier to achieve sensitive temperature control.
