Type 11 does not have any thermal mass, so when there is no flowrate through the tee-piece the outlet temperature is undefined. In that case Type 11 outputs the temperature at inlet 1 (i.e. the tank temperature, which is indeed sometimes much higher than 45 °C).<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>If you add a pipe (or anything with thermal mass) after the tee-piece you will get a nice constant plot at 45 °C.
