11. HATA KODLARI (Error Codes)
FAILURE TYPE
FAILURE
CODE
DESCRIPTION
Air Pressure Switch short F5
When heat demand is available, if APS is closed for 15sec although FAN
is stopped, this error is given. When APS is opened, normal operation is
started automatically.
Air Pressure Switch open F5
If APS is opened for 15sec although FAN is run, this error is given.
When APS is closed while fan is running, normal operation is started
automatically.
Outdoor probe error F6
If Outdoor NTC probe is available and the temperature measured by
this probe is above 70°C or outdoor sensor is short circuit; this error is
given. CH operation keeps operating as if system is configured without
outdoor sensor. Normal operation starts when the error condition is
disappeared.
Low Water Pressure error F7
If water pressure is <= 0.4bar this error is given. Error is cleared
automatically if water pressure >= 0.8bar
Water pressure display also shows the actual pressure value during F7
error.
Safety thermostat open F1
If safety thermostat is opened for 3 sec this lockout is given. RESET
potentiometer action is required in order to reset the failure.
DHW NTC probe error F2
If DHW NTC probe is open or short circuit, or it is damaged this error is
given. Normal operation is started when error is disappeared. This
error is not given during CH operation.
CH flow NTC probe error F3
If CH flow NTC probe is open or short circuit, or it is damaged this error
is given. Both DHW and CH demand is stopped during this error.
Normal operation is restarted when error is disappeared.
Ionization error F4
If there are 3 consecutive flame errors when Gas Type is selected as NG
or 1 flame error when Gas Type is selected as LPG, this lockout is given.
RESET potentiometer action is required in order to reset the failure.
Ionization component
error
F0
In case of an out-of-range ionization signal for 15 seconds this error is
given. Normal operation is started automatically when the error
condition is disappeared for 2 seconds.
False flame error F4
If there is a false flame condition for 10 seconds, this error is given.
Normal operation is started automatically when the error condition is
disappeared.
Gas valve feedback error F9
If there is an error in gas valve feedback check circuitry, this lockout is
given. RESET potentiometer action is required in order to reset the
failure.
Low voltage error F8
If supply line voltage is below 155 ±15V, this error is given. Normal
operation restarts when voltage is higher than 160 ±15V.
High Water Pressure error F15
If water pressure is >=2.8bar this error is given. Boiler keeps working.
If water pressure is >=3.5bar this error is given. Boiler stops working.
Error is cleared automatically if water pressure <=2.6bar.
Water pressure display also shows the actual pressure value during F15
error.
