Programming The P.c.b - Immergas INTEC 30 System External Installation Instructions Manual

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) (Fig. 2-1) 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.
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.
