PID A and B (for flow) are available, plus selections for ratio, cascade, carbon potential, three position step (for positioning actuators without slidewire feedback), position proportional (for positioning actuators with slidewire feedback) and ON/OFF control. HEAT/COOL is provided through reverse scaling outputs and dual tuning selections. Digital inputs and outputs to the PID blocks allow a variety of control strategies.
