Resetting of the factory settings

Check and note down the CN1 and CN2 values on the data label (see chapter 5.3.1. ).
• Press for 10 seconds, until the display shows "Cn";
• Press , the display will show "1.0" (in the example, the second digit "0" flashing represents the value of "CN1");
• Press "RESET" to change the second digit to the "CN1" value indicated in the data label;
• Press to confirm; the display will show "2.0" (in the example, the second digit "0" is the value of "CN2");
• Press "RESET" to change the second digit to the "CN2" value indicated in the data label;
• Press to confirm; the display will show "End";
• Press "RESET" to exit the menu and in the case that other error codes appear;
• Turn the boiler off and then on again to run the automatic vent (5 min duration) and diagnostics procedure.
Any customised parameters, set before the reset to the factory configuration, will have to changed manually.

Setting the climatic curve

Connect the external probe to the X14 (OS) terminal and the "On/Off" type
ambient thermostat to terminal X8 as shown in the figure.
To change the curve set the following parameters:
• CP000 : maximum flow temperature setpoint (Tm).
• CP230 : changes the slope of the curve (from 0,0 to 4,0).
• CP210 : changes the value (offset) of the minimum flow
temperature (Tm). Does not change the slope of the curve.
Te External temperature (°C)
Tm Heating flow temperature (°C)
The parameters for setting the climate curve can only be
changed using the Service-Tool (see paragraph 9.1).
