3.12.1 - ADJUSTMENT OF THE GAS VALVE ELECTRIC MINIMUM
3.12.2 - ADAPTATION OF THE POWER TO THE HEATING SYSTEM
E.g. !DEA CS 24
to decrease the output of the
boiler to 23 kW, obtain a pres-
sure value of 10.3 mbar (read on
the pressure gauge), modifying
the HP parameter (about 40)
.

1 ACTIVATION
Activate the MINIMUM POWER calibration function
(par. 3.11.1)
1 ACTIVATION
Collect the pressure gauge
differential to measure the burn-
er pressure (see par. 3.12)
2 EDITING THE VALUE
Modify parameter HP
(see par. 4.2) until the value cor-
responding to the wanted power
is obtained.
3 CHECK
Switch-on the boiler in heating
mode.
Check the pressure on the
pressure gauge, based on the
requested power, through the
chart.
EDITING THE VALUE
Turn the DOMESTIC HOT WATER knob ‘’C’’
