Error Code Descriptions (Visible using PC interface)
The meaning / explanation of the error number is listed below:
Lock-out condition codes:
FAULT 1
= Lockout signal after no flame and all ignition trials are expired. This error condition is stopping the
boiler and to get to the normal operation again, manual/remote reset is required. By using the local reset key,
number of resets are not limited. However, all remote resets (communication) are limited to 5 resets per hour.
FAULT 2
= False Flame indication
– error is created if flame current is detected in illegal situations (no heat
demand
currently present, gas valve closed, safety time passed). This error condition also requires manual reset action.
FAULT 3
= High Limit error
– if the safety cut-off switch opens due to an overheat situation in the application,
High Limit error will be generated.
FAULT 4
= APS related errors - if the APS is configured and the APS does not open or close within the
configured time limits Error 4 is generated. If the APS is not configured but an APS switch is detected on the
input Error 4 is also generated.
FAULT 5
= Fan Tacho signal error - if the measured fan speed is not within 900 RPM of the requested fan
speed in 20 seconds, error will be generated
.
FAULT 8
= Flame circuit error
– during normal operation of the ignition controller, flame circuit is regularly
checked. This check has predictable behaviour and several steps. If check fails, error will be set.
FAULT 9
= Gas valve drive circuit error
– during normal operation of the ignition controller, valve drive circuit is
regularly checked. This check has predictable behaviour and several steps. If check fails, error will be set.
FAULT 13
= All remote resets (communication)
– the number limited to 5 of remote resets in an hour is more
than allowed. Volatile lockout error is set; the error disappears after power off/on the boiler.
FAULT 21
= ADC error
– internal controller error.
FAULT 25
= CRC error
– matching error on CRC codes (different software versions).
Blocking condition codes:
The boiler controller recognizes also the fault situations that can block the heat demands but do not lead to
lockout condition.
When the error condition becomes resolved, error will disappear but will be also written into the history data.
FAULT 26
= Reset Knob error
– if the button is switched on for more than 10 seconds, error is set till the Reset
Knob will be released.
FAULT 34
= Low Mains voltage (less than 150 +/- 10 VAC) will trigger this error. When Mains brought back
(164-176 VAC), error is resolved in 10 seconds.
