<br>Dear all,<br><br>I want to get a constant outlet temperature (for example 70°C) for my collector in a DHWS. For this purpose I am using a Iterative Feedback Controller (Type22) to control the the pump mass flow in my collector circuit. <br><br>As Input values for this type I have entered:<br><br>Setpoint: 70<br>Controlled variable: collector outlet temperature linked<br>On / Off signal: 1<br>Minimum control signal: 0<br>Maximum control signal: 1<br>Threshold for non-zero output: 0.15<br>Tolerance on tracking error: 0<br><a title="Senden (STRG+Enter)" href="javascript:;" onclick="ComposePage._sending = true;" id="SendMessage"><span class="Label"></span></a><br>I have linked the control singnal of this type and the pump (type 3b) together.<br><br>It should work but as I plot the collector outlet I always have no flow rate and not a constant outlet temperature from the collector.<br><br>What am I doing wrong?<br><br>regards,<br>Shahrdad<br><br><br><br><br> </body>
