“C2”, and another two-digit number. These two numbers
are the currently stored safety code of the valve
operating mechanism (e.g. 11 and 22 = safety code
1122).

Mounting
the valve operating mechanism on the radiator
• Manually turn the coupling nut to fasten the valve
operating mechanism on the valve (“1” in the
figure on the right side). When using valves by
“Danfoss” mount one of the adaptors enclosed on
the valve first. The figures on the next page show
the adaptors that have to be used for each valve.
Additional adaptors for other valves may be
purchased separately.
• Briefly press the (2) key on the valve operating
mechanism once (see figure on the right side).

When using ‘Danfoss’ valves mount one of the enclosed
adapters to the valve first. The figures 12a, 12b, and 12c
on the next page show the adapters that have to be used
for each valve. Additional adapters for other valves may
be purchased separately.

Please note:
If you purchased the valve operating mechanism separately and not as part of
a set comprising a heating control and valve operating mechanism, for
example, then the security code must first be transmitted. This is described in
detail in section 13 d).
• The valve operating mechanism acknowledges receipt of the first wireless protocol with a
signal tone.
• The antenna symbol s now permanently displayed.
• This completes the installation and you can now adapt the pre-programmed settings to your
individual needs.

Please note:
Proceed as described above, if you wish to install further valve operating
mechanisms.
Afterwards, the number of radiators/valve operating mechanisms must be set
on the heating control (section 13 e) and the security code must be transmitted
(section 13 d).
