<p>José Javier,</p>
<p> You are correct; Type56 is computing the amount of energy
required to maintain the space at the set point temperature you
have provided. You can artificially limit the amount of cooling
capacity that you make available, in which case the set point
temperature will not be maintained and you'll be able to see by
how much the temperature in the space is exceeding the set point.
<br>
</p>
<p> It sounds to me as though your simulation is mixing two
concepts: energy rate control and temperature level control.
Please refer to the archives of this mailing list for some
discussions on the topic.</p>
<p>kind regards,</p>
<p> David</p>

systems I have developed, the set temperature dropped
sometimes so now it seems weird to me that providing more
cooling power the set temperature doesn’t drop. It is clear
then that the cooling type from TRNBuild only begins to work
when temperature is higher than the temperature set.<o:p></o:p></span></p>

<p class="MsoNormal">I am not sure what you developed since it
seems you don't understand the basics. The set points of the
cooling are the temperatures that the zone Temp should be
higher than those set points so the systems starts working.
You got your required temperature as you set. How do you
expect to see less temperature while it is working? <br>
