<p>Dear Trnsys users,</p>
<p> </p>
<p>I have been using Trnsys for a months now and trying to model a simple single floor Zero energy house recently build in Rotterdam.</p>
<p> </p>
<p>Im now at the point where i am defining the floor heating with active layer in TRNBuild but i get this error : Specific fluid mass flow of active layer in surface 1 below minimum value of 12,98 kg/m2h.
</p>
<p>The minimum allowed inlet specific mass flowrate is valued at 16.68 kg/ h m2 so this error is very strange. I put the desired specific flow rate at 17.</p>
<p> </p>
<p>I have been increasing the massflow or lowering it still give the error.</p>
<p>Does trnsys studio recalculate specific value somewhere else? anyone has a another solution for implementing floor heating.</p>
<p> </p>
<p>Regards,</p>
<p> </p>
