3.3 Installing the temperature sensors
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 controller operates with Pt1000 temperature sensors which are accurate
to the degree, thus ensuring optimal control of system functions.
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
temperature range.
3.4 Installation of the additional functions via clamps Z1/Z2
The instructions are supplied with the expansion board. The installa-
tion has to be commenced accordingly and all warnings have to be
observed.

S6 is by default connected by bridge with the terminal block S- to enable
the heating circuit functions. If the bridge is removed, the heating circuit
is switched off. When connecting the remote adjuster RC21 the bridge
has to be removed. If a third party external thermostat is connected, it’s
