Only use lines of type JY(St)Y 2x2x0.8 mm.
The Wisotronic automatically detects whether sensors are connected and
which ones.
CAUTION
If no sensors are connected, only the current room temperature is
displayed and nothing can be damaged on the control.
However, please
be aware that in this case, the sun shading control system cannot function
correctly and that this may result in damage to your sun shading system.
Depending on the mounting situation, you can also directly route the line of
type JY(St)Y to the weather station multisense. It must be ensured that the
line is protected against UV radiation (e.g. in a conduit, hose) along its entire
length. Mount the line in such a way that water cannot penetrate the device
or enter into the building.
