DIVATOP D HF
Gas valve calibration
1. The parameter "q02" will be highlighted. The boiler will operate at maximum power according to the previously cal-
culated q02 value.
2. Press the DHW buttons to adjust the parameter "q02" until the maximum nominal pressure minus 1mbar is reached
on the pressure gauge. Wait 10 seconds for the pressure to stabilize.
3. Press the DHW button to adjust the parameter "q02" until the maximum nominal pressure is reached on the
pressure gauge. Wait 10 seconds for the pressure to stabilize.
4. If the pressure read on the pressure gauge is different from the maximum nominal pressure, proceed with increases
of 1 or 2 units of the parameter "q02" by pressing the
pressure to stabilize.
5. When the pressure read on the pressure gauge is equal to the maximum nominal pressure (the newly calibrated
value of the parameter "q02" is saved automatically), press the
parameter "q01"; The boiler will operate at minimum power according to the previously calculated q01 value.
6. Press the DHW buttons to adjust the parameter "q01" until the minimum nominal pressure plus 0.5 mbar is reached
on the pressure gauge. Wait 10 seconds for the pressure to stabilize.
7. Press the DHW button to adjust the parameter "q01" until the minimum nominal pressure is reached on the pres-
sure gauge. Wait 10 seconds for the pressure to stabilize.
8. If the pressure read on the pressure gauge is different from the minimum nominal pressure, proceed with decreases
of 1 or 2 units of the parameter "q01" by pressing the
pressure to stabilize.
9. When the pressure read on the pressure gauge is equal to the minimum nominal pressure (the newly calibrated va-
lue of the parameter "q01" is automatically saved.), recheck both adjustments by pressing the heating buttons and
correct them if necessary by repeating the procedure described above.
10. The calibration procedure ends automatically after 15 minutes or by pressing the button
