Equa 3 is the input for the lumped capacitance and this input is the

work: it seams the pump doesn’t exchange and the output temperature
remains constant.

Without seeing your project my first guess is that you don't have anything turning the pumps on; the thermostat is only connected to the heat pump.

Beyond that, PLEASE add some pipes between the components and make sure you are operating at reasonable time steps - 5 minutes or so.
