The LCD then displays
‘Sync’,
the current security code and ‘120’.
The
heating control counts down from ‘120’ in steps of 1 second and then returns
to the normal operating mode.
During this time the heating control cannot be
operated. The heating control now synchronizes
its operation with the valve operating
mechanisms.
Please make a note of the displayed security code on
a slip of paper and write the name of the room, in
which the heating control is installed, underneath the
code.
You will need this information if you intend to
register the heating control to a ‘FHZ1000’ home radio
central unit.
• Slide the heating control onto the wall holder from
above until it snaps into place. See figure on the right.
