13.3.Service functions
13.3.1.Parameters programming function
The parameters programming function permits to change the main launch and operation parameters of the boiler.
This function works only in the standby mode and permits to change the following parameters:
“P0” – ignition power 0 - 99 (100 steps);
“P1” – minimal heating power 0 - 39 (40 steps);
“P2” – maximum heating power 40 - 99 (60 steps);
“P3” – minimal time from switching off to the next putting into operation 0 - 14 (min). Factory settings:
For using the parameters programming function it is necessary to:
1)
Switch the boiler off, consequently pressing the button К5 (see Scheme 3, page 8) until the symbol
appears on the boiler’s display.
2) Disconnect the boiler from the power line;
3) Connect the boiler to the power line again. For 5 seconds there is a possibility to activate the programming
function;

4) Press and simultaneously hold the DHW and heating temperature reduction buttons (К2 and К4) for activating
the parameters programming function;
5) Quit hold of the buttons, when the code “P0” and the symbol appear on display;
6) Choose the parameter that must be changed, pressing the buttons КЗ or К4;
7) Press the button К5, in order to see the parameter value on display. The symbol on display will start
flickering;
8) Change the chosen parameter’s value, pressing the buttons К1 (value increase) or К2 (value reduction). In
order to increase speed of parameter changing you may press and hold the buttons К1 or К2;
9) Press the button К5, in order to keep the set parameter value and return to choosing parameters;
10) Repeat the cycle, beginning from point 6, in order to modify all parameters that you want to change;
11) Press the button К6 (RESET) in order to exit the programming mode.
Do not change the parameter Р3 with no extreme need.
