Kako se temperatura klišea približava zadanoj temperaturi smanjuje se protok struje kroz LED diodu optocouplera MOC3040. Zbog  toga, u jednom momentu (tipično 5°C prije zadane temperature), dolazi do pojave samo poluvalnog okidanja izlaznog triaca (BTW69 ili BTW68). Rezulat toga je nastavljanje grijanja sa samo 50% snage. Tako postoji mogućnost da se i ne postigne zadana temperatura. Zbog toga je postignuta temperatura klišea dosta neizvjesna i ovisi o naponu gradske mreže. To je posljedica tvornički loše dizajniranog regulatora temperature.</div> <bR> <script async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js?client=ca-pub-2650537455752702" crossorigin="anonymous"></script>  <ins class="adsbygoogle" style="display:block" data-ad-client="ca-pub-2650537455752702" data-ad-slot="7117608876" data-ad-format="auto" data-full-width-responsive="true"></ins> <script> (adsbygoogle = window.adsbygoogle || []).push({}); </script> <bR> <div>      Kvalitetno rješenje je naš dodatni sklop koji pretvara Vaš Hakro ON/OFF regulator temperature u pulsno širinski regulator temperature.
