a) Automatic operation. Operation of the boiler is controlled by the timed program as described in point 3-5.1 “Daily timed program for operation of the central heating system”;

b) Manual operation at the maximum temperature set. The boiler comes into operation regardless of

the timed program set. The operating temperature is that set using the	key (point 3-3: “Setting
the maximum central heating temperature”);

c) Manual operation at minimum temperature. The operating temperature is that set in point 3-6: “setting the minimum central heating temperature”.

The manual transition from positions a) and b) to position c) involves shut-down of the burner and disconnection of the pump after the post-circulation delay interval (the factory setting for this parameter is 3 minutes).

d) standby. The boiler does not work in central heating mode, although the frost protection function is still enabled.

(1)Hot water on/off key: Press this key to activate or inhibit this function, which is identified by the

appearance on the display of two black dashes under the symbol.

(4)Reset key. In case of a fault, referred to in point 3-7 “Faults and resetting the boiler”, the boiler can be restarted by pressing this key for at least two seconds.

If this key is pressed with no fault present, the display will show the message “E153”, and the same key has to be pressed again (for at least two seconds) to restart the boiler.

(9)Data key. This key can be pressed repeatedly to display the following information:

- Temperature (°C) of the hot water ();

- outdoor temperature (°C) (); only provided with the outdoor temperature sensor probe connected.
