Steca TR 0301

The controller TR 0301 was the first controller on the

market to be equipped with a graphic display, on which

an animated solar circuit of a solar energy system fully in-

dicates the operating mode of the system. The consistent

use of pictograms on the clearly arranged display ensures

easy operation. The controller was jointly designed with

an internationally renowned design centre. The control-

ler is used for monitoring and controlling of solar ther-

mal energy systems having a collector array and a storage

tank. In addition, the controller also has important sys-

tem monitoring and safety functions to ensure safe and

durable operation of the entire system. The numerous

additional functions of the bus-capable TR 0301 also in-

clude the option of limiting the storage tank tempera-

ture, 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 also supported by a sophisticated fault diagnosis sys-

tem. The multi-coloured LCD-backlighting ensures the

swift and safe detection of errors and allows faults to be

quickly rectified.

Steca TR 0201

The solar thermal controller TR 0201 provides everything

your solar thermal system requires for safe and long-la-

sting operation. The microprocessor-controlled regulator

monitors and controls thermal solar energy systems by

means of a collector unit and a storage tank. Apart from

controlling the solar system, the controller also adopts

important system monitoring and safety functions. The

system parameters and measured values can be viewed

and altered via the LCD-Display. The controller is equip-

ped with two inputs for recording the temperature and

one output for triggering the solar circuit pump. The

components delivered with the controller include a coll-

ector temperature sensor (type Pt1000) and a storage

tank temperature sensor (type Pt1000). The numerous

additional functions of the TR 0201 include the option

of limiting the storage tank temperature, a tube collec-

tor function, an anti-freeze 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 LCD

display ensures quick and safe location of occurring errors

and facilitates quick troubleshooting.
