f) Synchronising the valve operating mechanisms
("SYnC")
After selection of this menu item the heating control starts to transmit signals
to all valve operating mechanisms for about 2 minutes instructing them to
newly sychronise themselves.
After synchronisation the normal transmission program is continued and the
valve operating mechanisms generate an acoustic signal the moment they
receive the first correct signal.
• Press the "PROG" key until "Sond" is displayed.
• Use the selection wheel to select the special function "SynC".
• To confirm your selection, briefly press the "PROG" key.
• The safety code is displayed and the heating control starts to count down
from "120" in steps of 1 second. After these 120 seconds the heating con-
trol returns to the normal operating mode.
g) Test mode ("tESt")
Use this function to check whether all valve operating mechanisms receive
the radio signal correctly. The tested valve operating mechanisms acknow-
ledge correct reception with an acoustic signal. Use the selection wheel to
select the valve operating mechanisms to be tested.
If the large display shows a "0" (zero), all valve operating mechanisms are
tested, otherwise, only the valve operating mechanism assigned to the dis-
played number is tested. The timer in the left corner of the display counts
down to the point in time the next test cycle is to be started.
• Press the "PROG" key until "Sond" is displayed.
• Use the selection wheel to select the special function "tEST".
• To confirm your selection, briefly press the "PROG" key.
• Use the selection wheel to select the valve operating mechanism/s to be
tested.
• Press the "PROG" key to quit the test function.
