Controlling condensing temperature by controlling opening valve

Hi,

I want to control the condensing temperature by the opening of a valve as shown in the diagram below:

The valve is burkert 3280 controlled by tension 0 to 10 (V) as shown in the table below:

Let say, for example, the outlet fluid temperature (T_f_out) in range of 80 to 30 (°C) when the valve is totally close to full open, respectively, and I want to set the open of the valve to have T_f_out = 40 (°C), for instance. How can I do that using PID controller or any other way in LabView? Please, if someone knows, give me the code rather than send me somewhere. 

 Thanks

Hi,

I would like to know if there is any use for the Digital output of the pin 7 (blue)?

Thanks

Probably there is a use case…

I guess it is explained in the manual of your device! (RTFM!)

The DO pin uses the voltage supply for its logic levels, so FALSE is <=5V and TRUE is 10…30V, please take care of those voltages when trying to connect this signal to a TTL-compatible DI pin of your DAQ device!
