I have carefully reread the definition of IndirectHeatAlternateSetpoint in the Source Side Flow Control Mode field of the WaterHeater:Mixed and that of Indirect Alternate Setpoint Temperature Schedule Name.
After a few attempts, I set the main setpoint of my DHW tank (Setpoint Temperature Schedule Name) to what I actually want (60 degrees) and the Indirect Alternate Setpoint Temperature Schedule Name to the temperature up to which the primary source side (the HPWH in my case) can heat the water, so 40 degrees. This seems to give the desired result.
