C.3 Installing the temperature sensors
C.4 Installation of the additional functions via clamps Z1/Z2
Der Regler arbeitet mit Pt1000-Temperaturfühlern, die für eine gradgenaue Tempera-
turerfassung sorgen, um die Anlagenfunktion regeltechnisch optimal sicherzustellen.
Caution
If desired the sensor cables can be extended to a maximum of 30m using a
cable with a cross-section of at least 0.75mm².
Make sure that there is no contact resistance!
Position the sensor precisely in the area to be measured!
Only use immersion, pipe-mounted or fl at-mounted sensor suitable for the spe
-
cific area of application with the appropriate permissible temperature range.
Caution
S6 is by default connected by jumper with the terminal block S- to enable the
heating circuit functions. If the jumper is removed, the heating circuit is switched
off. When connecting the remote adjuster RC21 the jumper has to be removed.
If a third party external thermostat is connected, it’s electrical contacts has to be
floating and of low resistance = 0 Ohm.
Caution
Connect sensor S3 in an optional 2nd heat circuit.
The optional sensor 4 is used to switch off the additional heating at the buffer
storage.
The temperature sensor cables must be routed separately from mains voltage
cables, and must not, for example, be routed in the same cable duct!
Caution
The instructions are supplied with the expansion board. The installation has to
be commenced accordingly and all warnings have to be observed.
