PARAMETER MENU 

 

Parameter Setting: 

It’s necessary to perform the following sequence to enter parameter menu and make modifications in the menu: 

 

Move P2 (CH knob) to maximum position. 

 

Move P3 to “OFF” position and subsequently to “WINTER” position quickly. 

 

Repeat step 2 four times and then leave knob in “WINTER” position. Parameter menu is entered 
with displaying “P” and “Parameter No” consequently. Parameter no is 1 after entrance. 

 

 

To  increase  the  parameter  no,  move  P3  to  “OFF”  position  and  subsequently  to  “WINTER” 
position. 

 

After reaching the desired parameter no, move P3 to “OFF” position and wait for 5 seconds. 
Display will show the parameter value. 

 

 

To change the parameter value

, move P3 to “WINTER” position. Move P1 (DHW knob) to modify 

the value of selected parameter. 

 

 

Move P3 to “OFF” position. Wait for 5 seconds to store new value. 

 

It is now possible to select another parameter. 

 

Move P2(CH knob) when P3 is in WINTER position to exit from parameter menu. 

 

Note 1: If no movement is done with P3 in 2 minutes during parameter menu, menu is automatically exited 
after 2 minutes. 

Note 2: If the boiler is operating in CH mode while “PP07 CH Max Capacity” modification, the selected value 
is  not  immediately  applied  to  gas  valve  modulator,  it  is  applied  to  the  modulator  after  storing  the  new 
parameter. 

Note 3: All parameters are set to their factory settings if 45 is written to PP31.
