two  buttons  for  at  least  3  seconds.  The 

  icon  will  appear.  If  the  Single 

programming  mode  was  already  activated,  the  same  procedure  should  be 

used to deactivate it.

4.  When the adjustment is completed, release the buttons and wait for 5 seconds 

to exit the adjustment function.

NOTE:  It  is  always  possible  to  manually  change  the  Day/Night  mode  during 

a  24-hour  cycle.  However,  any  manual  return  to  the  Night  mode  will 

re-initialize  the  Night  mode  timer  to  the  latest  value  recorded,  which 

modifies  the  cycle  in  progress.  In  all  cases,  at  the  end  of  the  24-hour 

cycle,  the  thermostat  will  return  to  the  Night  mode  and  start  a  new 

cycle.  It  is  thus  not  necessary  to  readjust  the  Single  programming 

mode  when  a  manual  change  is  made  to  the  Day/Night  mode. 

 

When  turning  back  on  after  being  powered  off  (because  of  a  power 

failure, for example), the Single programming mode is deactivated, and, if 

previously activated, the 

 icon will blink. The blinking will stop as soon 

as you press down a button.
