Temperature controller for solar collector AFRISO EURO INDEX

Designed for manual or automatic control of solar systems for water
heaters with one hot water circuit. In automatic mode, the pump is
switched on when the temperature difference between the collector and
the storage tank has reached the adjustable value Ä T. If Ä T is below
the set value or if the maximum tank temperature Tmax. (adjustable) is
reached, the pump is switched off and there is no further charging.
The digital display of the solar controller displays one of three
selectable temperatures. The solar controller consists of a control unit
and a maximum of 3 temperature probes (2 probes are supplied with
the system). The control unit and the probes are connected by two-core
signal cables (maximum length 50 m).Two probes detect the temperatures
necessary to control the collector (TK) and the storage tank (TS).
A third probe can be connected to display the temperature of an addi tional measuring point (TM) (e.g. buffer tank).
