Remark: Every standard LED can be used. Be mindful of
the correct polarity.
Usually the long connecting wire is the anode and must
be connected with the terminal KL2.
The output current is limited to a maximum of 15 mA by a
series resistor in the Lambda-Control 1
plus
. Thus, it is
short circuit-proof.
Mount the sensor on the north-side of the building and
protect it against direct sun radiation.
Check the position by means of DCF77-Receiver
(see receiving indicator). The bar should completely
accumulate to the right.
The 5V feed-in is short circuit-steady.

Sensor input F5-3
Sensor input F5-4
Position F4: Upper accumulator
The order of the positioning of F5-1 to
F5-4 in the accumulator is not
important, as an average temperature
value is calculated.
The sensors F4 and F5 (1-4) have to be
positioned in 20% steps spread over
the entire accumulator height.
