<p>Łukasz,</p>
<p> My apologies for the delay in responding; we've been moving
offices and so I have gotten behind.</p>
<p> Controlling the active layer with operative temperature is
definitely something that I have done. Set up the operative
temperature as an output of your Type56 model and then in the
Studio, implement a thermostat that watches the operative
temperature and compares it to your set point value. The
thermostat model will then be connected to a pump (and perhaps a
boiler or a heat pump as well). Set the inlet temperature and mass
flow rate of liquid to your active layer as inputs to Type56. In
the Studio, the pump's output flow rate and temperature will be
the inputs to the Type56 active layer.</p>
<p>kind regards,</p>
<p> David</p>

<div>Dear David,</div>

<div>Thank you very much for your reply.</div>

<div>However, I still would like to ask about one thing, since I
am not much into this aspect. My goal is to control the flow
rate of Active Layer (ceiling heating system) within the
specified range of operative temperature. It means that I
would like to switched off the active layer when the
T_operative is higher than given value and then switch on
again when the temperature drops below other value.<br>
</div>
<div><br>
</div>
<div>Thus, I wonder how is it possible to change variables that
are defined in TRNBuild (flow rate) in TRNSYS? Do you have any
experience with that?</div>
<div><br>
</div>
<div>Kind regards,</div>
<div>Lukasz</div>

<p>Łukasz,</p>
<p> There aren't controls available within TRNBuild. Make
the inlet temperature and flow rate to the active layer
into inputs and then you can use whatever controls you
like in the Studio to turn pumps and other devices on
and off and thus control the temperature in the space.
Make sure to use a short timestep (1-5 minutes) or the
building will not stay reliably near its set points.</p>
<p>kind regards,</p>

<div>Dear All,</div>

<div>I am writing to you, since I would like to
ask if there is a possibility to control the
Active Layer - radiant ceiling heating system so
that I could trigger it on\off whenever the
airnode temperature is below or above the
certain limit? Is there an option to do it in
TRNBuild?<br>
</div>
<div><br>
</div>
<div>I would be grateful for any guidance.</div>
