What is the difference in switch control within this DCS?

As shown in the diagram, the difference between the rear and front versions is that there is an additional ‘R’ next to the three-way valve. No explanation is given for this in this version of the PID diagram; does anyone know what the difference is? Is the latter a reaction?
