the basic controller TR 0301. In addition to the speed control
of the solar circuit pump, the TR 0301sc also allows logging of
the solar circuit pump`s hours of operation, as well as recording
the minimum and maximum temperature values from the
collector and the storage tank. The controller is used for
monitoring and controlling solar thermal systems which have
a collector array and a storage tank. With its animated graphic
display, which is clearly arranged, the TR 0301sc visualises the
operational status as well as the complete solar circuit of the
solar energy system. The consistent use of pictograms helps
make the controller easy to operate. The controller also
performs important system monitoring and safety functions
to ensure safe and long-lasting operation of the entire system.
The numerous additional functions of the TR 0301sc include
the option of limiting the storage tank temperature, a tube
collector function, an anti-freeze function, a holiday and
storage re-cool 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
backlight ensures quick and safe location of occurring errors
and facilitates quick troubleshooting.
