Changing to the manual operating mode Changes to the setpoint temperature can be carried out at the adjusting ring of the operating unit in manual mode. Changing to the programming mode You can adjust the time program to your own requirements in programming mode. For further information please refer to Chapter "Adapting" from Page 20 onwards. "PROG" is displayed. 17 Operation Automatic functions Window function If you open a window so that the temperature drops strongly, the radiator controller closes the radiator valve in order to save energy. The message When the temperature rises again the radiator controller returns to normal operation, however at the latest after 30 minutes. The optional window contact HAC 30 allows you to couple the closing of the heating valve directly to the opening of a window. Protection against lime Once a week the drive unit opens and closes the radiator valve automatically and thus protects it against lime deposits. Anti-freeze If the temperature drops below 6 C, the drive unit opens the heating valve until the temperature rises above 8 C again. The anti-freeze function cannot be de-activated. 18 Operation Emergency operation when the batteries are flat Separate the housing of the drive unit from the valve lantern (refer to Page 5). In order to open the radiator valve: Turn the blue adjusting ring at the valve lantern towards the plus sign.
