Re: [TRNSYS-users] Controller problem

Dear Kaydee,

Make sure that you "connect it to itself" for Type2b:  the output control function to the input control function. Please see the TRNSYS SDHW example for reference (.\Examples\SDHW\SDHW.tpf). I have a few other suggestions for your simulation. You may change the line color and styles of your connection links between components to keep you simulation easy to follow and read. Last, make sure you connect the solar zenith and azimuth angle to your collector from the weather reader.

Best regards,

Matt Duffy

Subject: [TRNSYS-users] Controller problem

Hi..

Right now I'm doing a simulation of large scale solar assisted water heating..the problem is the controller,which is currently I'm using type 2b..I want to control the pump which will be turn ON if the temperature difference is 10degree C And it will turn OFF when the temperature difference between the evacuated tubes collectors and heat exchanger less than 2 degree C. What I want is to look the temperature out of the collectors. I try to do the simulation to the previous suggestion from before but it seem to have an error it in..I try so many ways but also failed..I attach the file as a reference. Please help!! Thank you very much!
