Flue Safety Thermostat Anomaly; Generic Boiler P.c.b. Anomaly; Flow Probe Anomaly; Domestic Hot Water Probe Anomaly - Immergas MINI NIKE 3 E Technical Manual

Technical Documentation
ERROR 03
The wiring between the flue safety thermostat and P.C.B. is OK.
03
a
Check/replace the flue safety thermostat. If the anomaly persists, replace the P.C.B.
Flue evacuation takes place correctly.
03
b
Replace the flue safety thermostat. If the anomaly persists, replace the P.C.B.
ERROR 04
The gas valve is operating correctly.
04
Replace the P.C.B. If the error continues check the quality of the power supply to exclude any external interference.
ERROR 05
The wiring between the flow probe and the board (connector X4
terminals 6-7) is OK.
05
Replace the NTC flow probe. If the anomaly persists, replace the P.C.B.
ERROR 06
The wiring between the DHW probe and the board (connector X2
terminals 4-5) is OK.
06
Replace DHW NTC probe. If the anomaly persists, replace the P.C.B.
ERROR 10
The boiler manometer displays a pressure exceeding 0.8 bar.
10
The wiring between the absolute pressure switch and the board is OK. No
Check/replace the system pressure switch. If the anomaly persists, replace the P.C.B.
ERROR 12
The wiring between the storage tank probe and the board (connector
X2 terminals 6-7) is OK.
12
Replace the storage tank NTC probe. If the anomaly persists, replace the P.C.B.

Flue safety thermostat anomaly

Restore the electric connection/replace the wiring.
No
Check:
- the correct flue draught using the relative tools (micro-manometer,
chromate mirror);
No
- the suitability of the flue exhaust pipes (measurements, pathways,
position on the roof, etc...).
Both checks must be performed with respect to local regulations.

Generic boiler P.C.B. anomaly

No Check the wiring of the electrical connection and make sure it is clean.

Flow probe anomaly

No Restore the electric connection/replace the wiring.

Domestic hot water probe anomaly

No Restore the electric connection/replace the wiring.

Insufficient system pressure

Restore the correct pressure by acting on the system filling valve.
N.B.: in this case it is always advisable to ensure that there are no leaks
No
in the central heating plant and check the correct factory-set value of the
expansion vessel.
Restore the electric connection/replace the wiring.
Storage tank probe anomaly
(in case of connection to an external storage tank, X versions )
The boiler prevents functioning in DHW mode but can function in CH mode.
No Restore the electric connection/replace the wiring.
