8.10 Analog output
The analog signal is effected via the 4-pin device socket M8 (see Fig. 8.2 on page17 or Fig. 8.4 on
page18 and Fig. 8.5 on page19). The output voltage is 0V ...10V. A suitable connection cable is
included in the scope of delivery.

9 Installation of the external temperature sensor
The temperature sensor has to be installed in a way that ensures that it extends into the water flow but
against the flow direction. The tip should protrude from the bottom of the pipe approximately 15mm.
1. Plug the external temperature sensor into the cooling circuit output using a T-piece (see Fig. 7.4 on
page16).
X The temperature sensor should be positioned as close to the cooling circuit output of the mirror or the
absorber as possible.
