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 speci
fi
c area of application with the appropriate permissible tempe-
rature range.
Caution
S6 is by default connected by jumper with the terminal block S- to ena-
ble 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 con-
nected, it’s electrical contacts has to be
fl
oating and of low resistance =
0 Ohm.
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 obser-
ved.
