The process have a heating and cooling circuit. Chiller is in use when airflow higher is than
21°C, heater is than closed.
Heater is in use when airflow lower is than 21°C, chiller is closed. I use a actuator with position feedback and limit stop signals, the controller is a step controller.
How can i control two actuators, for cooling and heating circuit? What can i do to prevent the actuators working against each other? Whats the best solution, working with one or two controllers in a control loop?
