Activate login mode:
Insert the batteries into the radiator actuator, making sure that the polarity is correct. On appears and the login mode is active.
After successful login, e.g. on the HomePilot® , the HomePilot® appears as 1 in the display.
The DuoFern radiator actuator will attempt to perform reference runs after logging on. If you do not mount the radiator actuator directly, this will cause the battery to discharge quickly.
If you do not install the radiator actuator immediately after logging on, you should remove the batteries and only reinsert them shortly before installation. It is then not necessary to log on again.
After the batteries are inserted, three dashes first appear in the display, after a few seconds the display automatically jumps to POS, press the menu key once to start the installation drive.
The display jumps to InS. Subsequently, the last set temperature is displayed.
