<p>Dear all,</p>
<p><br> I have the questions about Active Layer:<br>1. The floor heating area is 27.2 m^2 in our test room, but the floor area is 40 m^2. Like this situation, Can I set two floors in TRNBuild? One is the floor with 40 m^2, another is floor with 27.2 m^2 active layer? Or others?</p>
<p><br>2. I only know the power of this floor heating 1400 W. How can I define it? Or by what method to stand for this power?</p>
<p><br> Many thanks in advance!</p>
<p><br> Br.</p>
<p><br> wang<br><br></p>

<br>Yes I know quite all the tricks you've said, and I did read the manual, and did a small building, and I perfectly know I would have been able to do so in a training course within 2 hours.<br><br>But the problem is for a bigger building !! (even with the manual next to the keyboard...)<br>
I think my problem is that I (still?) don't know how to draw perfectly from the first click in sketchup, and that I have to erase, cancel, etc. And then, it is a big mess.<br>Anyway, thanks for taking into account our concerns, I have my answer that some people manage to be efficient with Trnsys3D!<br>

<br>> Dear Igor,First of all, please make sure that your timestep is small -<br>> probably under 0.125 hour. Type Type2b collector is recommended for a<br>> simulation like this. Honestly, there are few simulations where one should use<br>

Subject: Re: [TRNSYS-users] Type 2b controller dead band problem.<br>I have taken your advice and made the timestep, 0.125hr
<div><br></div>
<div>Still I cannot get it to work. it is still switching on the time step instead of the dead-band temp.</div>

<div>Hi
<div> </div>
<div>I have read the information, I have tried to increase parameter 1, I have also looped the controller to its self. Still it does not work</div>
<div>I have also tried changing many other parameters and have spent a lot of time on this problem. still with no luck.</div>
<div> </div>
<div>Any other suggestions?</div>

Also, you should increase the value of parameter 1, to the default value at least (the influence of this parameter is explained at the type 2 documentation, I recommend you to read it, together with the generic section for controllers at the trnsys help)<br>

<div>Dear Trnsys
<div> </div>
<div>I am experiencing problems with a simple<b> type 2b controller</b>.</div>
<div> </div>
<div>I am using a solar collector type 564b</div>
<div> </div>
<div>I am trying to compare the temperature of the output of the collector with output of the tank, getting a temperature difference. I have set the dead band from 4-10 degrees C.</div>
<div> </div>
<div>In the simulation as the temperature rises to 10degrees difference, the control signal is 1 switching the pump on correctly. but after this the controller only switches every time step. I have tried shortening the time step... and changing other parameters.. still with no success.</div>
<div> </div>
<div>I have attached the file.</div>
<div> </div>
<div>Yours Sincerely</div>
