WARNINGS SIGNALLING ANY BLOCKAGE AND SUGGESTED SOLUTIONS

If necessary, the reason for a shutdown is shown on the display.

1) Broken PTC H2O: Shuts down due to the water temperature sensor being broken or disconnected.

Check connection of the sensor to the control board. Verify functionality by means of a cold test

2) Check/extract.: Shuts down due to the revolution sensor of the smoke extractor motor detecting an anomaly.

- Check smoke extractor functionality (connection of the revolution sensor)

- Check smoke channel for dirt

3) Stop Flame: Shuts down due to a drop in smoke temperature (intervenes if the thermocouple detects a smoke tempe-

rature that is lower than that which is set, thereby interpreting it as a flame failure).

The flame may not go on for the following reasons:

- lack of pellets

- too many pellets in the combustion chamber have suffocated the flame

- the maximum thermostat / pressure switch / water safety thermostat has intervened to 'stop' the gear motor

4) AFNO start-up block: Shuts down due to incorrect smoke temperature during ignition (intervenes if the flame fails

to appear within a maximum of 15 minutes, or if the ignition temperature is not reached).

Distinguish either of the following cases:

The flame has NOT appeared

Verify:

- positioning and cleanliness of combustion

chamber

- resistance functionality

- room temperature; if lower than 3 °C a fire

lighter is needed

5) No Electricity: Shuts down due to an electricity failure.

Check electricity connection and drops in voltage.

6) TC Failure: Shuts down due to a failure occurring in the thermocouple or it being disconnected

Verify connection of thermocouple to the control board. Verify functionality in a cold test.

7) °C smoke/high: Shuts down due to excessive smoke temperature

An excessive smoke temperature may occur because of the following: unsuitable pellet type, anomaly in smoke extrac-

tion, blocked smoke channel, incorrect installation, gear motor 'drift'.

8) T. MAX H2O: Shuts down due to water temperature being higher than 90 °C.

An excessive temperature may occur because of the following:

- system too small: ask the DEALER to activate the ECO function

- blockage: clean the exchanger pipes, the combustion chamber and the smoke outlet.

9) NO depr. is detected: (intervenes if the flow sensor detects insufficient circulation in the combustion air).

Circulation may be insufficient if the door is left open due to

- the door not closing properly (e.g. seal),

- a malfunction in the air outlet or smoke expulsion,

- the combustion chamber being clogged,

- the flow sensor being dirty (clean with dry air).

Check flow sensor limits. Ask the DEALER to check parameter settings.

The depression alarm can also be signalled during the ignition phase.

RTC RD error

The thermal stove does not stop but the error appears on the display. The buffer battery of the control board needs

changing.
