COn
” (con
fi
guration) appears
on the display.
Once entered in con
fi
guration menu, pressing “ “ scrolls through
the various parameters, identi
fi
ed with
P
and the parameter
number, from
P01
to
P24
. The con
fi
guration end is displayed with
“
End
”. Press “ “ again to save the con
fi
guration and and return to
normal operation.
Press the “ “ button, at any time, to exit from the con

To prevent unauthorised access to the con
fi
guration remove the
internal jumper (
JP5
) shown in Fig. 6. Any attempt to access the
con
fi
guration will display the
fl
ashing “ “ icon.
The installer con
fi
guration consists of two lists of parameters:
- main parameters
P01
to
P24
(table 1)
- extended parameters
C01
to
C19
(table 2)
The extended parameters
C01
-
C19
allow an advanced thermostat
con
fi
guration.
When the display shows “
COn
“ at con
fi
guration start or “
End
“ at
con
fi
guration end, press the “ “ button to access the extended
parameters.

DESCRIPTION OF MAIN CONFIGURATION PARAMETERS
The main installer con
fi
guration parameters are shown in table 1
and explained below.
P01
: System type selection.
2 pipes system: when con
fi
gured for a two-pipes system the
controller drives one valve only, wired at the “heating“ valve
terminals, both when heating and when cooling, as the same
valve is going to control either hot or cool water
fl
ow.
See wiring diagram in Fig. 8
a
and
b
.
In case of a two-pipes system without valve, and therefore with no
wirings at the valve output terminals, make sure to set parameters
P03
and
P04
to “fan control“ in order to get an effective regulation.
4 pipes system: when con
fi
gured for a four-pipes system the
controller drives both valves outputs in order to activate either the
hot water or the cooling one according to the actual requirements
of the controlled environment.
See wiring diagram in Fig. 8
c
and
d
.
Electric heater system: the regulator is con
fi
gured to control a
system equipped with an electric heater: see the section “Electric
heater system” for more details.
Integrating electric heater system: the regulator is con
fi
gured to
control a system equipped with an electric heater: see the section
“Integrating electric heater system“ for more details.
Heat pump system: the regulator is con
fi
gured to control a system
equipped with a heat pump: see the section “Heat pump system“
for more details.
P02
: This parameter sets the way how the controller switches from
the cooling mode (summer) to the heating mode (winter) and vice
versa.
