<p>Max,</p>
<p> If you have access to the TESS HVAC library you will find a
Type508 cooling coil model that includes the control mode that you
are looking for.</p>

<pre class="moz-quote-pre" wrap="">Hi there,
I have a question concerning a cooling coil.
I want to model a cooling coil Type 123. My goal is to implement a set
temperature for the outlet fluid temperature. For example: Cooling power
should only be provided if the inlet air temperature is above 20°C and
then the coil should have a set temperature for the outlet air temperature
to be around 21°C.
How can I do this? On/Off Controller doesn't work because there is always
the error that the cooling capacity must be greater than 0 which obviously
isnt the case if the inlet temperature is below 20°C.
I have tried it with an equation and a gt-function but the result isnt
satisfying.
Thanks for your help!
Regards,
Max
