Gas Valve Calibration; Range Rated - Riello Start Aqua Condens 25/60 BIS Installer And User Manual

Live electrical parts (230 Vac).
The following icons are displayed:
1. during absolute/domestic maximum calibration
during the minimum calibration
during the maximum heating calibration
during the slow ignition calibration confirm the adjustment
code by pressing the ENTER key.
End the procedure by removing the JP1 and JP3 jumpers to store
the set values.
The function can be terminated at any time without saving the set
values while maintaining the initial ones:
- removing jumpers JP1 and JP3 before all 4 parameters have
been set
- turning the mode selector to
- removing the mains voltage 15 minutes after its activation.

The calibration does not entail the ignition of the boiler.

By rotating the heating setpoint selector knob, the number of
rotations expressed in hundreds (e.g. 25 = 2500 rpm) is auto-
matically displayed.
The calibration parameter display function is activated with the
selector on summer or winter and pressing the CO button on the
card regardless of whether or not there is a heat request. The
function cannot be activated if a remote control is connected.
When this function is activated, the calibration parameters each
appear (in the order shown below) for 2 seconds. The relative icon
is indicated in line with each parameter, and the fan rotation value
expressed in hundreds.
1. Maximum
2. Minimum
3. Maximum heating
4. Slow ignition
5. Maximum heating adjusted

GAS VALVE CALIBRATION

- Power the boiler
- Open the gas tap
- Turn the mode selector to
- Remove the housing and turn the instrument panel (refer to
previous chapters for the detail of the figures)
- Undo the fixing screws of the cover to access the terminal board
- Press the "CO" button once.

- Wait for the burner to fire. "ACO" is displayed. The boiler operates
at the maximum heating output. The "combustion analysis"
function remains active for 15 min. If an inlet temperature of
90°C is reached the burner turns off. It will ignite again when the
temperature falls below 78°C.
- Remove the screw and the cover on the air distribution box
- Insert the flue gas analysis probe into the sockets provided on
the air box
- Press the "combustion analysis" button a second time to reach
the number of revolutions that corresponds to the maximum
domestic hot water output (table 1).

- To exit the "combustion analysis" function, turn the mode selector
to the required position.
- Pull out the flue gas analysis probe and replace the plug.
- Close the instrument panel and reposition the cover
- The "combustion analysis" function is automatically disabled if
the card generates an alarm. In the event of an anomaly during
the combustion analysis phase, perform the reset procedure.

RANGE RATED

This boiler can be adapted to the heating requirements of the
system, in fact it is possible to set the maximum delivery for heating
operation of the boiler itself:
- Disconnect the power supply to the boiler
- Turn the heating water temperature selector to its maximum
- Remove the housing and turn the instrument panel (refer to
previous chapters for the detail of the figures)
- Unscrew the fixing screws of the hatch on the terminal board
cover
- Insert the jumper JP1
- Power up the boiler.
The display shows "ADJ" for about 4 sec.: it is then possible to
rpm
change the maximum heating value by means of the heating water
temperature selector and the CO button in order to set and confirm
the desired value.
The icon will appear on the display
Finish the procedure by removing the jumper JP1 to store the set
values.
Once the required output has been set (maximum heating), indicate
the value on the self-adhesive label supplied. For subsequent
controls and adjustments, refer to the set value.
