Steca Temperature Difference Regulator

Steca STR1 Temperature Difference Regulator

Our 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.

  • Individually adjustable switch-on temperature difference, switch-off hysteresis and maximum storing temperature
  • Display unit for the storing and collector temperature
  • Temperature sensor with error flag
  • Storing temperature limitation
  • Easiest assembly and handling
  • Coordinate safety concept
  • Hand-gear control
  • Status display
