<div dir="ltr"><div><div><div><div><div><div><div><div><div><div>Hi everybody,<br><br></div>I'm stuck with trying to control the outside temperature of a stratified storage tank (type534) with the controller type2b and the auxiliary heater type6.<br>
</div>When i first connect only the auxiliary heater to the tank, the auxiliary heater was ON only when there was a flow stream.<br></div>Then i connected a controller to maintain the auxiliary heater even if there is no flowrate. the outside storage tank temperature has to be always at 55°C.<br>
</div>But sometimes the outside temperature of the tank is lower than 55°C.<br></div>I think i put a sufficient maximum heating rate in the type6.<br></div>I connected the tank nodal temperature to the lower input temperature of the controller<br>
</div><div>I set the upper input temperature of the controller to 55°C<br><br></div>Can somebody help me to understand why i can't maintain the outside temperature at 55°C?<br><br></div>I'll be grateful for any advice<br>
<br></div>Thanks in advance<br><br></div>Rajaa<br></div>
