9. (Step 4) Mounting the anti-theft/
The anti-theft/tamper protec-
tion device prevents the radio
energy-saving controller and
its batteries from simply being
removed and stolen.
• Push the anti-tamper protec-
tion device into the guide from
below until it engages (E). The
battery compartment can now
not be opened.
• Attach the upper shell (F) and lower
shell (G) to the union nut until they en-
gage. The bars (H) on the shells must slot
into the flange spaces.
• Insert the M3 hexagon socket-head screws (I) and fas-
ten them on the other side with nuts.
The upper shell and lower shell can be mounted in
any position.
The purpose of the lower shell, which is slightly longer,
is to prevent the radio energy-saving controller from
any attempts to remove it by unauthorised persons by
twisting it off. It is long enough to make contact with
the valve when the connection is rotated.
The lower shell should be attached in such a way
that it can as respond as quickly as possible to any
attempts to twist off the controller.
