Pushing  ESC  or  OK  buttons without  selecting  the  number 

of  days,  "vacantion  mode"  will  not  be  active,  and  the 

cronothermostat will return to the previous operating mode. 

 

The  “vacation  mode”  has  a  timer  function  and  the  day 

counter  decrements  by  one  at  midnight,  the  number  of 

days remaining is shown on the display when the mode is 

active. 

At  the  end  of  this  time,  when  the  counter  is  cleared,  the 

cronothermostat  switches  to  "automatic  mode"  and  follow 

the weekly program has been set. 

 

Pushing  again  button 

,  you  can  activate  the  "summer 

mode",  which  is  active  demand  hot  water  but  not 

environment thermoregulation. 

 

 

 

The  management  of  the  cronothermostat  by  the  user  is 

much simplified. The functions are not distinct between the 

functions  relating  to  boiler  and  functions  relating  to 

thermoregulation.  

 

Pushing again button 

 you switch to another option: 

 

 

 

This option allows you to turn off the system (temperature
