Strain relief casing
Note
Never place the half shells of the strain relief casing to-
gether before you have prepared the cable and connected
the plug.
Cable cross-section
Sheath diameter
Insulation stripping length
f Prepare the end of the cable by stripping the sheath and f
insulation.
f Push the wires into the side of the plug labelled with the f
terminal assignment. If necessary, press a screwdriver on the
clamping springs to make it easier to insert the wires.
f Carefully put the plug into the flat insulation semi-shell of f
the strain relief casing so that the terminal labelling remains
visible. The locking tabs on the sides of the plug must engage
in the top tabs of the strain relief casing.
f Make sure that the strain relief gutter is inserted in the upper f
insulation semi-shell of the strain relief casing.
f Push the upper insulation semi-shell carefully onto the lower f
insulation semi-shell. The locking tabs on the sides of the
lower insulation semi-shell must engage in the recesses of
the upper insulation semi-shell.
Programming unit
The programming unit is connected with an I²C bus. See program-
ming unit operating and installation instructions.
The programming unit is delivered with an adaptor cable whose
wires are marked with digits. Connect the adaptor cable in such a
way that the same numbers are connected to one another.
Safety equipment for stove/fireplace operation
f Install the safety equipment in such a way that it interrupts f
the appliance power supply when required.
Intensive ventilation switching contact
You can connect a floating switching contact, the actuation of
which switches the appliance to intensive ventilation. You can set
the runtime for intensive ventilation in parameter P2. After this
time has expired, the appliance returns to the previously appli-
cable fan stage.
Window contact
You can connect a window contact to terminal X18. The window
contact is required for passive cooling. The appliance checks
whether a window contact is connected and activated at X18.
The window contact must be an N/O contact.
