OpenDTA Reviews

Excellent tool to check and optimize heat pump operation. Great feature to export data to CSV format too.

Thanks for fixing the bugs, which occured in the former software revision 0.18, where you changed from the library Qwt to QCustomPlot. With OpenDTA I was able to optimize my brine/water heat pump in my residental house on my own. My technician installed inadequately: I noticed the badly attached TVL sensor, which interrupted the operation and announced error "WPStörung", when the heat pump changed over from heating my fan-assisted-radiators to heating my hot tap water. I identified a sporadic electromagnetic interference in the TBW input, which started the brine pump baseless. I avoided, that the heat pump empties my photovoltaic accumulator at night. I reduced, how frequent the compressor starts, which lengthens the lifetime. The radiator-circuit pump HUP did swongly stops, because the existence of my radiator-circuit buffer tank wasn't set in the controller.

excellent programm, easy to use

I just created a user account with sourceforge to thank you for this .. please keep going

New version! Now with internationalization! Available languages: - Czech - English - German Translator welcome. ;-)

Greatfull program, better than official DTA analyzer. Is Possible to translate different language, because Germany is too hard... I try to change word in xxx.txt but doesn't work.

A very useful and stable program, even in this early state. Thanks!
