Now you need to synchronise the (first) valve operating mechanism (‘001’ on the
display) to the new security code.
Proceed as follows to carry out this synchronisation:
• Remove the battery compartment cover of the (first) valve operating mechanism by sliding
it down.
• 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 ‘
AC
AC
AC
AC
AC
’ is displayed.
• Press the ‘
PROG
’ button on the ‘FHT80B-3’ heating control to start transmitting the security
code to the valve operating mechanism.
• 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 valve operating mechanism acknowledges that it has received the first normal radio
signal with a signal tone.
Now repeat these steps for all the other valve operating mechanisms in the room
(‘002’, ‘003’... on the display).
After the last valve operating mechanism has been coded the heating control
automatically returns to the normal operating mode.
If the heating control is used to control several valve operating mechanisms, in other words,
several radiators are located in one room, you should make a note of which valve operating
mechanism belongs to which radiator, that means the number.
If coding of a valve operating mechanism fails (for example, due to bad reception, a low battery
or similar), the security code can be transmitted to this valve operating mechanism again at a
later time.
• Proceed as described above and skip the valve operating mechanisms that have already
been coded by briefly pressing the ‘
PROG
’ button.
• If the LCD shows the number of a valve operating mechanism that has not yet received a
security code, press the control button on this valve operating mechanism until ‘
AC
AC
AC
AC
AC
’ is
displayed on the valve operating mechanism and you hear 3 signal tones. Also see the
information above.
• Now press the ‘
PROG
’ button on the heating control to get the heating control to transmit the
security code. The valve operating mechanism uses a tone sequence to acknowledge that
it has received the code correctly.
Afterwards, replace the valve operating mechanism’s battery compartment cover. The valve
operating mechanism uses a signal tone to acknowledge the first receipt of a normal radio signal.
