■ Standard PID control
It is available to control two independent loops.
Loop 1: Control by Pv1 and Mv1.
Loop 2: Control by Pv2 and Mv2.
■ Heating and cooling PID control
It is available to control one loop.
Loop 1: Control by Pv1, heating Mv1 and cooling Mv2.
Loop 2 is not available.
■ Heating and cooling ON/OFF control
It turns ON (voltage/current output at 100%) until the Pv reaches the SP, and turns OFF (voltage/current output at 0%) once it is reached.
