These values will be transferred to the associated named controls of the CONTAM PRJ file via Type98.<br>
Note that if you want to control more than one item in CONTAM with a single value, you can use phantom control nodes within the PRJ.<br>
You can reference the named control nodes within CONTAM with a phantom node.<br>
This is demonstrated in the cottage_dcv example provided with Type98 files.<o:p></o:p></span></p>

Have you run the example case provided with Type98?<br>
This example provides control of simple AHS flows and an HRV fan via control signals provided to/from CONTAM from/to TRNSYS via Type98, i.e., both signal directions are demonstrated to synchronize system flows between CONTAM and Type56.<br>
<br>
If you want, you can send me your files, and I will look at them.<br>
<br>
There are some things you can do to help debug your issues:<br>
- Create report controls in the associated CONTAM project file and view outputs in <your project>.log file.<br>
- Plot/output signals in TRNSYS to ensure correct logic, etc.<br>
- Set the first value in the air file to 3 to write detailed data exchange info to the Type98.log file available in the Type98 AppData directory, e.g., in Windows 7 C:\Users\<you>\AppData\<Roaming>\NIST\Type98.<br>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span style="font-size:10.0pt;font-family:"Arial","sans-serif"">I use Contam3.1 and TRNSYS 17 to couple Type56 and Type98 with each other. The coupling is going as planned. I have
used constant controllers in Contam to get manual inputs, so I can vary the opening area of my paths. When I manually set the inputs from the controllers to have a value (e.g. 1) in Type98 everything is well (I get values of the flow), and when I try to connect
it to an equation with a constant value, I still have a flow. But when I connect the input values to an equation with a variable value (e.g. from 1 if the outdoor temperature is 17C and above and 0 otherwise) I don't get any flow (looking over 8760 hr) - it
is as if it can't read variable values. </span><o:p></o:p></p>

I get a flow. The only thing is, I get a convergence error because the Type56 isn't converging. This gives me some pretty huge errors when I compare my TRNSYS-Type98 model with TRNSYS-Type97 model. </span><o:p></o:p></p>
