12 times in 2 hours of operation.
Carry out appropriate checks. Reset may be performed from the
CCI/DDC (or from the S61 board via menu 2, parameter 21). If the
code persists, contact authorised Robur TAC.
E 408 FLAME CONTROL UNIT ERROR
E 12 on unit and condenser inlet temperature
increasing by over 10 °C within 1 hour.
Carry out appropriate checks. Reset may be performed from the
CCI/DDC (or from the S61 board via menu 2, parameter 21). If the
code persists, contact authorised Robur TAC.
u 410 INSUFFICIENT HOT WATER FLOW
Insucient water ow (the circulator is on and
the owmeter measure a low water ow).
Reset occurs automatically when correct water ow is restored.
E 410 INSUFFICIENT HOT WATER FLOW
u 10 code is repeated, or code u 10 is active for
1 hour
Reset may be performed from the CCI/DDC (or from the S61 board
via menu 2, parameter 21). If the code persists, contact authorised
Robur TAC.
u 411
INSUFFICIENT ROTATION OF OIL
PRESSURE PUMP
Insucient rotation of oil pressure pump. Reset occurs automatically 20 minutes after the Code is generated.
E 411
INSUFFICIENT ROTATION OF OIL
PRESSURE PUMP
u 11 code generated twice in 2 hours of
operation.
Reset may be performed from the CCI/DDC (or from the S61 board
via menu 2, parameter 21). If the code persists, contact authorised
Robur TAC.
u 412 FLAME CONTROL UNIT ARREST Failure to ignite burner.
Reset occurs automatically when the solenoid valve opens again
(new attempt at ignition), or after code is active for 5 minutes.
E 412 FLAME CONTROL UNIT ARREST Flame arrest signal.
Reset may be performed from the CCI/DDC (or from the S61 board
via menu 2, parameter 20). If the code persists, contact authorised
Robur TAC.
E 416
HOT OUTLET WATER TEMPERATURE
SENSOR DEFECTIVE
Fault (interruption or short circuit) on hot outlet
water temperature sensor.
Reset may be performed from the CCI/DDC (or from the S61 board
via menu 2, parameter 21). If the code persists, contact authorised
Robur TAC.
