After encoding of the last valve operating mechanism is fin­
ished the heating control automatically returns to the nor­
mal operating mode.
If the heating control is used to control several valve oper­
ating mechanisms, i.e. if there are several radiators in one
room, you should make a note of the assignment between
valve operating mechanisms and radiators (radiator num­
bers).
If the encoding of a valve operating mechanism fails (e.g.
due to bad signal reception, low battery voltage, or the
like) transmission of the safety code to this valve operating
mechanism can be repeated at a later time.
• Proceed as described above and skip the valve operat­
ing mechanisms that have already been encoded by briefly
pressing the “PROG” key.
• If the LC display shows the number of a valve operating
mechanism that has not received a safety code yet, press
the push­button on this valve operating mechanism until
“AC” is displayed on the valve operating mechanism and
you hear an acoustic signal (3 signal tones).
• Press the “PROG” key on the heating control to initiate
transmission of the safety code by the heating control. The
valve operating mechanism acknowledges correct recep­
tion of the code with an acoustic signal (sequence of
tones).
Replace the cover of the battery compartment. The valve
operating mechanism acknowledges correct reception of
the normal radio signal with an acoustic signal.
