* Synchronisation is not required by WDC and CMP25-2 controllers.
The signal cable between DD2+ and controller must not ex-
ceed 50 meters.
After the wiring connection, DD2+ needs to be synchronised with
the controller. To synchronise the DD2+, hold key for 30
seconds. After you hear two successive beeps, release the key.
The DD2+ synchronisation is now in progress. When you hear
another beep, the DD2+ is synchronised and you can continue
with your work.
DD2+ needs to be synchronised with the controller after all
the temperature sensors are connected.*
