P66/A
With the external probe present it defines the minimum flow tempera-
ture corresponding to operation with maximum external temperature
(see graph Fig. 1-5) (it can be set between 20°C and 50°C)
N.B.:
to continue one must confirm the parameter (press “D” or exit
adjustment “P66” by pressing “C”)
25 °C
P66/B
With the external probe present it defines the maximum flow tempera-
ture corresponding to operation with minimum external temperature
(see graph Fig. 1-5) (it can be set between 50°C and 85°C)
N.B.:
to continue one must confirm the parameter (press “D” or exit
adjustment “P66” by pressing “C”)
55 °C
P66/C
With the external probe present it defines at which minimum external
temperature the boiler must operate at the maximum flow temperature
(see graph Fig. 1-5) (can be set between -20°C and 0°C)
N.B.: to continue one must confirm the parameter (press “D” or exit
adjustment “P66” by pressing “C”)
-5°C
P66/D
With the external probe present it defines at which maximum external
temperature the boiler must operate at the minimum flow temperature
(see graph Fig. 1-5) (can be set between 5°C and +25°C)
N.B.: to continue one must confirm the parameter (press “D” or exit
adjustment “P66” by pressing “C”)

3.9 PROGRAMMING THE P.C.B.
The Magis Victrix ErP boiler is set up for possible
programming of several operating parameters.
By modifying these parameters as described
below, the boiler can be adapted according to
specific needs.
Attention:
If the international language is to be
restored (A1), see the instructions described in
Par. 2.7 (customisations menu - M3).
By pressing the button "D" it is possible to access
the main menu, divided into three main parts:
- Information“M1” (See “User” Chapter)
- customisations “M3” (See “User” Chapter)
- “M5” configurations, menu reserved for the
technician and for which a password is re-
quired.
To access programming, press button “D”, turn
the heating temperature selector switch (3) and
scroll through the menu items until reaching
“M5”, press button “D”, enter the password and
set the parameters according to requirements.
Listed below are the items in the “F5” menu
with default parameters and possible options
indicated.
By turning the central heating temperature se-
lector switch (3) scroll through the menu items.
By pressing button “D” access the various levels
of the menu and the choice of parameters is
confirmed. Press button “C” to go back one level.
(The first item of the various options that appears
inside the parameter is that selected by default).
