Setting Pump Post-Circulation - Biasi RinNOVA 24S User Manual And Installation Instructions

• Using key 10 or 11 it is possible to change the
value of parameter 15 from a minimum of 01
to a maximum of 60 based on the selected
curve of the K coefficient in Figure 5.28 (the
value read on the display corresponds to the
decimal values of the K coefficients).
• By pressing key 12 (Figure 5.29) confirmation
of the inserted value is obtained.
• By pressing keys 12 and 13 together (Figure
5.29) you will exit without changing the value
(return to the parameter list Figure 5.31).
• Press keys 12-13-14 together for 10 seconds
(Figure 5.29) to exit "programming mode".
At this point the plant delivery temperature
will follow the trend in relation to the set K co-
efficient.
If the ambient temperature is not comfortable,
you can increase or decrease the heating sys-
tem delivery temperature by ± 15°C with the
keys 13 (decrease) and 14 (increase) (Figure
5.29).

5.15 Setting pump post-circulation

The pump, in heating function, is set for a post-
circulation of about one minute at the end of
each heat demand.
This time can be changed from a minimum
for more than 3 seconds
to display the K REG
to change the
mode (Figure 5.34).
