Venting (Par. 2090)
The function is automatically enabled at the first start-up and at
each reset of the power supply.
When the function is active, the message “Air” is displayed.
During the venting, the circulator is enabled, so that the air
which may be present inside the system circuit can exit through
the automatic drain valve of the device.
The status of the light guide changes to flashing green.
During venting it is possible to deactivate the function by set-
ting the parameter 2090 = 0
In case of low pressure error (E040 and E041) or pressure
transducer error (E042) the venting cycle will stop.
Overtemperature protection (Par. 2096)
This function prevents a possible safety thermostat triggering.
If the boiler temperature exceeds the value set in this parame-
ter, the burner turns off and the circulator continues its opera-
tion to discharge the excessive heat (post-circulation).
Circulator activation every 24 hours
Every 24 hours the circulator is activated for 30 seconds (only
in heating mode 0,1,4).
This function prevents the circulator from getting stuck in a de-
termined position.
Test mode (chimney sweeper)
When this function is enabled (Par. 200 = 1) the equipment
works for a time (which cannot be changed) of 15 minutes at
maximum power, then it goes back to its normal operation.
It is possible to interrupt at any moment the operation in test
mode (Par. 200 = 0).
If the delivery probe of the device reaches 82°C (maximum
operating temperature) the burner turns off.
Attention! Hot water runs through the system. Danger of scald-
ing with hot water!
Ignition failure
If an ignition or operating anomaly occurs, the thermal unit dis-
play will show a text message (small digit) and a number (large
digit), which vary according to the anomaly detected.
For a detailed description, see the error list.
There are 3 error levels:
- Permanent (Loc)
- Temporary (Err)
- Alerts (AttE)
The section with the large digit will display the error number
and , according to the error / alert, a message which will cycli-
cally blink together with the number.
For a detailed description, see the error list.
Permanent Error
The text “Loc” is displayed together with the permanent er-
ror number. The icon
indicates that the burner is disabled.
The equipment must be manually reset by keeping the key
“ENETER/RESET” pressed.
Temporary Error
The text “Err” is displayed together with the temporary error
number.
The icon
indicates that the burner is disabled.
The lock-out error must be solved.
Warnings
The text “AttE” is displayed together with the alert number.
The equipment is not locked out, but its functions may be lim-
ited (according to the alert).
Checks during and after initial start-up
Once the boiler has started up, make sure that it shuts down
and re-starts properly when:
- By changing the set temperature;
- By moving the main switch from (
I
) to (
0
) and vice versa;
°C
- The room thermostat or timer setting is changed;
- Check that the circulator rotation is free and correct;
