ERROR 15
The P.C.B. is configured for instantaneous open chamber boilers. No
15
Replace the P.C.B.
ERROR 20
The detection electrode and the relative wiring are integral.
20
Replace the P.C.B.
ERROR 24
The buttons on the control panel function regularly (check that a
"click" is heard when the button is pressed).
24
Replace the P.C.B.
ERROR 27
The boiler pump functions correctly.
N.B.: make sure that the pump functions at maximum speed.
Any CH system zone valve or cut-off cocks are open.
27
The NTC flow probe is OK (10 kΩ at 25°C).
Check/clean/replace the main heat exchanger. If the anomaly persists, replace the P.C.B.
ERROR 31
The Remote Control is connected correctly.
N.B.: only remote controls supplied by Immergas can be used (CAR
V2 o CAR Universal).

Configuration error

N.B.: This P.C.B. can be used for instantaneous sealed chamber / open chamber
boilers or with a storage tank. The board automatically recognises the type of boiler
by means of the relative wiring of the P.C.B.
For MINI NIKE type boilers, check the following connections.
- flue thermostat wiring.

Parasite flame block

Check/replace detection electrode/replace wiring.
No

Push button control panel anomaly

No Check that there are no keys blocked or jammed under the control panel.

Insufficient circulation

No See section B
Restore circulation in the CH system by acting on the closed devices
and also check:
- the correct positioning/functioning of the boiler by-pass;
No
- the opening times of any zone valves (when necessary, it is possible to
delay ignition of the burner by acting on the boiler "P8" parameter);
- the correct functioning of any thermostatic valves.
No Replace NTC probe.

Loss of remote control communication

Check the connection between P.C.B. (clamps 40-41) and remote control
No (IN+ and IN-) carried out respecting the polarity and using a dedicated
line to prevent interference.
