Continue until all 7 days of the week are completed.

The choice of the programs described above may be replaced by other types of programs imposed by different conditions.

These different conditions are linked to the three auxiliary switches E1, E2 and E3, and to one of the five settable annual programs.To 

each of these conditions, any chosen program may be associated (via Master or via PC). If more than one of these conditions is present, 

the priority order is: E1, E2, E3, ANNUAL.

Priority means that the first condition to appear in the list prevails.

The only condition present or the first  in order of priority, is indicated as follows:

– E1 = XXXX alternating with the associated program. XXXX is the name given to input E1; default: HELP (call)

– E2 = XXXX alternating with the associated program. XXXX is the name given to input E2; default: WIND (window open)

– E3 = XXXX alternating with the associated program. XXXX is the name given to input E3; default: ABSE (absent)

– ANNU. X = an annual period is running with an associated program. ANNU X alternates with the program.

It is possible to adjust the annual program setting locally  ------------------------------------------------------------------

10.0.4  

Local adjustment of the annual program is useful when the user wishes to use heating/conditioning even when the system 

is off as an annual program is in operation (e.g. HOLIDAY PERIOD). USER MUST REMEMBER TO RESET THE PREVIOUS 

PROGRAM WHEN LEAVING. This operation can be carried out using the same procedure used for choosing the programs

WARNING: when a program is set using the auxiliary switches E1, E2 or E3, user may adjust the desired room temperature as 

if it were not a set program.
