Operating instructions

c) Mounting the valve operating mechanism to the radiator

• Manually turn the coupling nut to fasten the valve operat-

ing mechanism to the valve (‘1’ in the figure on the right).

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.

• Briefly press the button (2) on the valve operating mecha-

nism once. See the figure on the right.

•‘

‘

0%’ is displayed.

• Close the battery compartment again.

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).
