• Set the second part of the code (00 to 99) using the scroller.
• Confirm the code by briefly pressing the ‘PROG’ button.
• ‘Code SynC 01’ appears on the display.
Ö
The (first) valve operating mechanism is now synchronised to the new device code.
• Remove the battery compartment cover of the (first) valve operating mechanism by sliding it down and out.
• Press the button on the valve operating mechanism for approx. 3 seconds until you hear 3 signal tones. The valve
operating mechanism is now ready to receive, and its LCD displays ‘AC’.
• Press the ‘PROG’ button on the FHZ1000 to start transmitting the code.
• The valve operating mechanism acknowledges that it has received the code correctly with a tone sequence.
• Replace the valve operating mechanism’s battery compartment cover.
• The first reception of a normal radio signal is confirmed with a signal tone.
Ö
These steps are repeated, if further valve operating mechanisms are located in the room (‘Code SynC 002’
on the display, and so on).
Once all the valve operating mechanisms have been coded, the control centre automatically returns to the
normal operating mode.
Please note:
If the control unit controls several valve operating mechanisms (there are several radiators in the room), you
should note which valve operating mechanism belongs to which radiator and which number it has.
If the coding of a valve operating mechanism fails, transmission of the security code to this valve operating
mechanism can be repeated later.
• Proceed as described above and skip the valve operating mechanisms that have already been encoded by briefly
pressing the ‘PROG’ button.
• If the display shows the number of a valve operating mechanism that has not yet received a code, then press the button
on this valve operating mechanism until the display on the valve operating mechanism shows ‘AC’ and it emits 3 signal
tones.
• Now start the code transmission by pressing the ‘PROG’ button on the control centre or the control unit.
e) Setting the number of valve operating mechanisms, ‘no H’
This menu item allows you to change the number of radiators (valve operating mechanisms) that are to be controlled.
Ö
When an additional valve operating mechanism is installed, it is important that it receives the same security
code, otherwise it will not respond to the radio commands from the control centre. This occurs while the
settings are made:
• Keep the ‘PROG’ button pressed until ‘Sond’ (special) appears on the display. Then release the ‘PROG’ button.
• Use the scroller to select the special ‘no H’ function.
• Confirm this by briefly pressing the ‘PROG’ button.
• Use the scroller to select the number of radiators (1 to 8).
• Confirm your selection by briefly pressing the ‘PROG’ button.
• ‘Code SynC 001’ appears on the display.
The (first) valve operating mechanism is now synchronised to the new security code.
