Steca TR 0301 U Differential Temperature Control Systems from Solar Hot USA

Solar Hot USA offers different models of solar differential controls such as TR 0301 U, TR 0502 U and TR 0603 U from Steca. The Steca TR 0301 U differential temperature control system offers automatic and safe operation for domestic solar water heating systems. It circulates the heat transfer fluid between storage tank and solar thermal collectors during the day. This temperature controller is a microprocessor-based controller that uses two RTD type sensors to check the tank and collector temperatures by digital accuracy. The LCD screen displays different real time information such as system temperatures.
