• Use 15 or 16 (Figure 5.31) to change the
value of parameter P07:
00 = probe disabled (preset)
01 = probe enabled (12kOhm)
02 = probe enabled (10kOhm)
• Press 12 or 13 (Figure 5.31) to confirm the
value entered and return to the list of param-
eters Figure 5.33.
• Press 17 (Figure 5.31) to exit "programming
mode".
• Press 13 and hold until the LCD display
shows the code P08, indicating entry into
"parameter P08" (Figure 5.35).

• Use 15 or 16 to change the value of param-
eter P08 from a minimum of 1.0 to a maxi-
mum of 3.0 based on the selected curve of
the K coefficient in Figure 5.29 (the values
shown on the display is the K coefficient
decimal).
• Press 12 or 13 (Figure 5.31) to confirm the
value entered and return to the list of param-
eters (Figure 5.35).
• Press 17 (Figure 5.31) to exit "programming
mode".
At this point the system delivery temperature
will follow the trend in relation to the set K co-

If the room temperature is not comfortable,
you can increase or decrease the heating
system delivery temperature by ± 5°C using
the 15 (decrease) and 16 (increase) buttons
(Figure 5.31).
With heating temperature setting 25-85°C
(factory preset), the temperature trend for K
2.0 is shown in Figure 5.36. With temperature
setting 25-55°C the temperature trend for K
2.0 is shown in Figure 5.37. With temperature
setting 50-80°C the temperature trend for K
2.0 is shown in Figure 5.38.
