Below,  the  page shows  the minimum  and maximum  limits 

set on the thermoregulation board. 

 

The  temperature  represents  the  maximum  value  that  the 

heating  set-point  can  be  taken  in  termoregulation 

proportional  mode  and    compensation  mode.  For  more 

details  see  the  following  paragraph,  in  particular  the 

description of the submenu "Heating control". 

 

Pushing  again  button 

  is  proposed  the  submenu 

“PARAMETERS MENU” 

 

 

 

The  submenu  "PARAMETERS  MENU"  (described  in  the 

relevant  section)  allows  you  to  see  the  parameters  of  the 

boiler and allows you to manage advanced functions, such 

as  transparent  parameters  (TSP),  unlock  and  water  filling 

(if provided). 

 

If  the  boiler  supports  the  integration  of  solar  panels,  the 

next screen is relative to the operation of solar thermal. 

(If the solar function is not active is displayed, however, the 

boiler panel described below.) 

 

 

 

This menu has a frame fixed. The options previously seen 

remain  displayed  for  20  seconds,  then  the  display  returns 

to  the  main  screen,  which  depends  on  the  chosen 

operation mode. (manual, automatic, estate, vacation, off). 

In  this option,  however,  if  the  user  does  not  push  ESC  or 

not push 

 or 

, the crhonothermostat continues to show 

the  control  panel  with  its  solar  collector  and  accumulation 

temperatures and pump status. 

 

Similar applies to the next screen, the control panel of the 

boiler. 

 

 

 

This screen displays the main information on the boiler. 

In  the  first  line  appears  the  system  pressure,  the  flame 
symbol 

 , if the boiler is turn on, and the percentage of 

flame  modulation.  In  case  of  lockout  or  anomaly  appears 
the symbols (

 o 

) and the error code for diagnostic. 

In the second line appears the circuit heating temperatures 

(left) and return temperature (right).  

In the last line appears the DHW temperature and the DHW 

flow rate in liters per minute. 

Pushing again the button 

 you return to the first option. 

 

 

 

In  case  it  is  already  active  the  automatic  mode,  it  is 

indifferent push NO or OK.
