After entering the MENU use the       key to 
select the required setting. The messages 
are  shown  in  the  bottom  section  of  the 
screen like this:

One  of  three  operation  modes  can  be 
selected:      

day else the factory default temperature of   
23.0 ºC will be used for all the 24 hour base.

After  entering  the  MENU  and  by 
consecutive presses of the key               the 
message       (High Temperature Limit)  will 
be  shown  on  the  bottom  of  the  screen             
as  well  as  the  initial  value  30.0  ºC.  By 
pressing the key             we can change this 
temperature  between  the  lower      limit             
and the value of 30.0 ºC. By pressing the 
key       and then immediately the      key       
the lower section of the screen shows the 
message          (Low Temperature Limit) as 
well as the initial temperature of 6.0 ºC. With 
the  key              we  can  adjust  the  value 
between  6.0 ºC and the value of the upper 
limit.  The  two  limits  define  a  temperature 
area that can be used by the user to enter 
the  desired  temperature.  The  selection  of 
the limits influences the manual adjustment 
of the temperature and is independent from 
the  operating  mode  of  the  unit  (manual, 
daily  weekly)  and  does  not  have  any 
influence  on  the  programs  for  daily  or 
weekly operation.
