The device lets you choose the type of
algorithm to apply for managing the
system between:
-Differential
-Proportional Integral
Differential Algorithm A
If, on screen A, the differential algorithm
type has been chosen using the
arrows, press the

Note. The range of adjustment goes
from 0 to 1°C.
This function is useful for environments
that are particularly hard to air condition,
with extreme variations in external tem-
perature, and it commands the switching
on of the system as shown in figure C.
Proportional Integral Algorithm
If, on screen A, the proportional integral
algorithm is chosen using the
rows, the screen in figure D is displayed.
Press the
button to access the screen
in figure E which, lets you choose one
of the 4 available programs using the
arrows (see table).
The first 3 (P1 - P2 - P3) cannot be
