Steca TR 0603
The new solar thermal controller TR 0603 with his abso-
lute advantages as animated graphic display and elegant
design continues the success enjoyed by this family of
controllers. This controller provides everything your solar
thermal system requires for safe and durable operation.
The controller TR 0603 is used for monitoring and con-
trolling of solar thermal energy systems having two dif-
ferently aligned collector arrays and a maximum of three
domestic hot water or buffer storage tanks. The large dis-
play panel shows the animated control circuits, which al-
low you to view the operating conditions of each system.
The consistent use of pictograms on the clearly arranged
display ensures easy operation. 15 pre-programmed solar
energy systems allow universal application. The TR 0603
controller also has 6 inputs for recording temperatures
or pulse values, as well as 3 speed-controlled outputs for
controlling pumps or switching valves.

Display example
Here are merely a selection, designed to show the many and
diverse function displays of the TR 0603 controller.
Graphical display
The fully animated graphical display of the TR 0603 controller
is a new feature in the field of solar thermal controllers. With
this display, Steca has managed to represent the different sys-
tem layouts and numerous functions in a clearly laid out dis-
play that is easy to understand. This is supported by the ability
to display information in a number of different languages.
Apart from the usual high quality of all Steca products, the
strength of this controller lies in the ease of use and the high
level of functionality.
