5.23 Factory reset

RESET restores all parameters to
the factory settings.
• Enter "programming mode" by following the
procedure indicated in section "Accessing
installer parameters" on page 43.

• Press 12 and hold until the LCD display
shows the code A49, indicating entry into
"parameter A49" (Figure 5.52).

• Use 15 or 16 (Figure 5.51) to change the
value of parameter A49:
39 = factory reset
• Press 12 or 13 (Figure 5.51) to confirm the
value entered and return to the list of param-
eters (Figure 5.52).
• Press 17 (Figure 5.51) to exit "programming
mode".

5.24 Examples of hydraulic systems
with hydraulic separator (option-
al)
The hydraulic separator creates a reduced
load loss zone that makes the primary circuit
and secondary circuit hydraulically indepen-
dent.
In this case, the flow rate that passes through
the circuits depends exclusively on the char-
acteristics of the flow rate of the pumps.
Therefore by using a hydraulic separator, the
secondary circuit's flow rate is circulated only
when the relative pump is on.
When the pump for the secondary circuit is
off, there is no circulation in the corresponding
circuit and therefore the flow rate pushed by
the pump in the primary circuit is by-passed
through the separator.
With a hydraulic separator, the production cir-
cuit can have a constant flow rate and the dis-
tribution circuit can have a variable flow rate.
