Derivative action selection function

A derivative action appropriate for each of fixed value action and ramp action can be selected and the action
characteristic can be improved using this function.
(1) Action

This setting effectively
prevents the temperature from
being affected by disturbance,
though the performance to
follow the set value can be
low.
This setting allows the
temperature to follow the set
value well, though the
disturbance effect is great.
