Simultaneous Temperature Rise Function

This function allows several loops to reach the set value (SV) at the same time. Simultaneous temperature rise can be
executed on up to two groups separately by setting a group of the channels where temperatures rise at the same time. This
function is good for controlled objects in which the temperature rise have to be completed at the same time. Aligning the
temperature rise completion time enables an even control of temperatures without partial burning or partial heat expansion.
In addition, the channel that has reached the set value (SV) first does not need to be kept warm at the set value (SV) until the
last channel reaches the set value (SV), leading to energy saving.
