must also be mounted on the valve pin (see Fig. B on
the fold-out page).
3. Use the union nut (1) to assemble the device
onto the adapter (15) or directly onto the radi-
ator valve.
4. Press the button
OK
(10 b). The adaptation
starts automatically.
The device adapts to the radiator valve. To do this,
the radiator valve is opened and closed several
times so that the device learns the respective end
points. This process may take a few minutes.
Several adaptation cycles may be necessary be-
fore the radiator valve is detected correctly, de-
pending on the condition of the valve.
If the adaptation does not work, even after several
attempts, assemble the device again using a spac-
ing ring.
Assembling/Disassembling the Union
Nut (Poland / Austria)
In the case of supplies to Poland and Austria, the
union nut (1) is not preassembled. Use the thread
gauge supplied to determine which union nut (1)
must be assembled on the radiator valve.
1. Slide the union nut (1) on the radiator valve
until you hear a distinct "click" and the union
nut (1) can be rotated freely.
If the union nut (1) is fitted the wrong way around
on the radiator valve, the union nut (1) can be
simply screwed off and then fitted the right way
around.
