• $V_{S,min}$, $V_{S,max}$, $V_{L,min}$, $V_{L,max}$;
• $V_i$, $V_o$;
• $(UA{)}_i$, $(UA{)}_o$;
• hydraulic parameters of the heat exchangers, pipes, and check valves, represented at first level by $(C_{d}A{)}_{\mathrm{e}\mathrm{f}\mathrm{f}}$;
• thresholds $\Delta P_{\mathrm{o}\mathrm{p}\mathrm{e}\mathrm{n}}$, $\Delta P_{\mathrm{c}\mathrm{l}\mathrm{o}\mathrm{s}\mathrm{e}}$;
• position of each check valve upstream or downstream of its heat exchanger;
• kinematic reference levels ${\Lambda }_L^{\ast }$, ${\Lambda }_S^{\ast }$, when used.
