FAULT FINDING
4 .1 Display diagnostic
The display indications provide help in the diagnosis of fault find -
ing.
The control panel display gives other information for the user.
The following table gives fault code, error and the reson for the
fault.
Er 01 + RESET Lack of burner ignition
Er 02 + RESET Safety thermostat lockout
Er 03 + RESET Other faults
Er 04 +
Faulty primary circuit (no water or absence
of flow)
Er 05 +
Faulty fan control system
Er 06 +
Faulty C.H. temperature probe NTC flow
Er 08 +
Faulty external temperature probe NTC (if fit -
ted)
Er 09 +
Faulty flue temperature probe NTC
Er 10 + RESET Lockout – flue temperature probe NTC (Flue
temperature > 120 °C)
An 11 Parasite flame
Er 12 +
Faulty central heating temp. probe NTC (re-
turn)
Er 14 + RESET Faulty pump (absence of water flow in the
main circuit) or primary temperature above
105 °C
Er 15 + RESET None or too low water flow; Faulty pump
(temp. difference between probes higher
than 35° C)
Er 16 + RESET Possible exchange of NTC probes (Flow or
Return) or pump wrongly mounted (upside –
down)
Er 17 + RESET Faulty C.H temperature probe NTC (Flow or
Return)
Er 18 + RESET Faulty primary circuit (no water or absence
of flow)
Er 25 + RESET Flame detection error
Er 69
Wiring error lockout
L3 Useful output limitation (temperature differ-
ence between probes higher than 25° C):
Boiler test performing
Td Thermostat Delayed: Boiler test performing
Maintenance required
The wrench symbol is flashing (without show -
ing any error)
4 .2 Programming the maintenance period
1 To enter in the parameters setting mode press sequentially
the 3 keys "B - C - A" (Figure 4.1) and hold in for 10 second
until the display shows Figure 4.2.

2 Scroll the various parameters using keys "A" or "C" (Figure
4.1) until the LCD display indicates the letters Pr , alternating
with the code 28 , indicating entry in “parameter 28" (Figure
4.3).
Figure 4 .3
3 Press keys "B" and "A" (Figure 4.1) at the same time until
the LCD display indicates the value of parameter 28 (e.g. 12
default value) Figure 4.4.
Figure 4 .4
4 Pressing key "A" makes it possible to change the value of
parameter 28 from 0 to 48 months. It is possible to set pa-
rameter 28 to 99 thereby disabling the maintenance request
(symbol will disappear from the display).
5 By pressing key "B" (Figure 4.1) confirmation of the inserted
value is obtained.
6 By pressing keys "B" and "C" (Figure 4.1) together, you will
exit without changing the value (return to parameter list Fig-
ure 4.3).
7 Press keys "B - C - A" (Figure 4.1) together for 10 seconds to
exit "programming mode".
