    <p>Vajhie,</p>
    <p>  You should use Type2. Almost all of the examples that involve
      solar water heating systems use Type2; I would suggest that you
      look at one of them to understand how to implement Type2.</p>
    <p>kind regards,</p>

        <div dir="auto">I have a solar heating simulation.I have a
          storage thank in it. I want to say that whenever the inlet
          temperature of the tank (outlet collector temperature) is less
          than outlet temperature of the tank (inlet collector
          temperature), turn off the pump. From which component I should
          use? And how?</div>
