I want to exploit thermal energy of solar collector when the temperature of the tank T_load exceeds 50 ° C (the tank does't need heating), in which the dividing valve will direct the flow to the tank when T_load <50 and to vertical exchanger when T_load> 50.
how I link T_load tank with controller type 2b to give sign to diveting valve . i use this equation to control the diverting valve c-out =gt(T-loud tank,50) but i get error.
Best regards
