Steca TR 0301sc+

3 inputs, 1 output

Description

The Steca TR 0301sc+ controller is the speed-controlled version of the basic Steca TR 0301 controller.

In addition to speed control of the solar circuit pump, the Steca TR 0301sc+ also offers the option of recording the operating hours of the solar circuit pump and the minimum and maximum value storage of the collector and storage tank temperatures.

The controller monitors and controls solar thermal systems with one collector array and one storage tank. The Steca TR 0301sc+ visualises both the operating status and the complete solar circuit of a solar system via a graphically animated and clear display. The consistent use of pictograms facilitates the easy operation of the controller. The controller also takes over important system monitoring and safety functions, ensuring the continuous and safe operation of the entire system. The numerous additional functions of the Steca TR 0301sc+ the maximum storage tank temperature, a tube collector function, a frost protection function, a holiday or re-cooling function and the option of selecting the temperature display in degrees Celsius (°C) or Fahrenheit (°F). The operational safety of the system is supported by sophisticated fault diagnostics. The multicoloured LCD backlighting ensures that any faults that have occurred can be found quickly and reliably, helping to quickly rectify any faults.
