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