Checks Following Conversion To Another Type Of Gas; Programming The P.c.b - Immergas VICTRIX EXA 28 1 ERP Instruction And Recommendation Booklet

3.7 CHECKS FOLLOWING
CONVERSION TO ANOTHER TYPE
OF GAS.
After making sure that conversion was carried
out with a nozzle of suitable diameter for the
type of gas used and the settings are made at the
correct pressure, check that the burner flame is
not too high or low and is stable (does not detach
from burner);
Note: all boiler adjustment operations must be
carried out by a qualified company (e.g. Author-
ised After-Sales Assistance).

The boiler also has electronic modulation that adapts the boiler potentiality

output
to the effective heating demand of the house. Therefore the boiler works
normally in a variable gas pressure field between minimum and maximum
power depending on the system heat load, setting fan speed (in rpm, hun-
dreds of revs are represented on the display).
N.B.: the boiler is produced and calibrated in the central heating phase at
nominal output. Approximately 10 minutes are needed to reach the nominal
heat output, which can be changed using the parameter (S3).

3.8 PROGRAMMING THE P.C.B.

The boiler is prepared for possible programming
of several operation parameters. By modifying
these parameters as described below, the boiler
can be adapted according to specific needs.
To access the programming phase, position
the DHW selector (5) on position "6", the CH
selector (6) on position "9" and press the "Reset"
(3) and "Summer/Winter" buttons for about 8
seconds (2).
Once the menu has been accessed, it is possible
to scroll through the three sub-menus present
(s, p, t) by pressing the "Summer/Winter" (2)
button for 1 second.
Description

Use the "DHW regulator" selector (5), to select
the parameter (inside the same sub-menu) and
rotate the "CH regulator" selector (6) to modify
the value according to the range available.
Press the "Reset" button (3) for 1 second to
memorise the variation of the parameters
Memorisation is represented via "88" on the
indicator (14) for 2 seconds.
Exit the programming mode by waiting for
15 minutes or by pressing the, "Reset" (3) and
"Summer/Winter" (2) buttons simultaneously.
