    <p>Patricia,</p>
    <p>  I would think that can use a simple heating thermostat; once
      the "heating" set point is achieved at the outlet of the heat
      exchanger, the control signal from the thermostat (which you will
      connect to a pump) will turn off. Which type you use depends on
      which TRNSYS version you are using. If you are using v18 then I
      would look at Type166. If you are using v17 then Type108 would be
      an option.</p>
    <p>kind regards,</p>
    <p> David</p>
