Steca TR 0301 U controller
Steca TR 0301 U controllerThe Steca TR 0301 U controller was specially developed for the North American market based on the Steca TR 0301 basic controller. With its special certification (ETL label) from a Nationally Recognized Testing Laboratory (NRTL) in the US, the controller meets the safety standards and minimum requirements of the North American market.
A feature of the Steca TR 0301 series of controllers is the animated graphic display, which offers a complete visualisation of the solar energy system's operating status and solar circuit.
The clearly arranged display ensures easy operation using pictograms. The controller was jointly designed with an internationally renowned design centre. The controller is used for monitoring and controlling solar thermal systems with one collector array and one storage tank. In addition, the controller performs important system monitoring and safety functions to ensure safe and long-lasting operation of the entire system. The numerous additional functions of the Steca TR 0301 U also include a maximum storage tank temperature function, a tube collector function, an anti-freeze function, a holiday and storage recool function as well as a choice of temperature indications in either degrees Celsius (°C) or Fahrenheit (°F). The operational safety of the system is supported by a sophisticated fault diagnosis. The multi-coloured LCD backlighting ensures quick and safe location of occurring errors and facilitates quick troubleshooting.
The Steca TR 0301 U controller is supplied with a pre-fitted US mains connection cable and a preinstalled, pluggable pump output.

Steca Temperature Difference Regulator
Steca STR1 Temperature Difference RegulatorOur STR 1 includes everything that is needed for a thermal solar system. Apart from the controller for temperature differences an electronically controlled limitation of the storing temperature has been built in. Of course, it is possible to adjust hysteresis, temperature difference and max. storing temperature individually. By using the hand-gear control you can adjust the pump for testing or other operations. A display indicating the temperature informs you about the collector temperature to be stored. Another very important point was the breakdown safety switch which does not lower your solar system’s performance since it is very low in self-consumption. The regulator is supplied including a collector temperature sensor and a storage temperature sensor in the lower storage tank area for limiting the maximum storage temperature.
