BIOREACTOR_TEMP_CTRL
Bioreactor jacket temperature control, split-range heat/cool with a jacket low-temperature limit.
When to use it
Use BIOREACTOR_TEMP_CTRL when a jacketed bioreactor or fermenter holds broth temperature with a heating service and a cooling service on the same jacket, and the vessel wall must not be driven below the temperature the culture tolerates.
