on body of generator Reset limit thermostat manually: operation will be restored
automatically when the cause ceases.
E 401
GENERATOR LIMIT TEMPERATURE
THERMOSTAT u_01 code active for 1 hour, or u_01 code
generated 3 times in 2 hours of operation.
Contact authorised Potterton TAC.
u 402 FUMES THERMOSTAT
High temperature detected by exhaust fumes
thermostat Reset occurs automatically when the condition that generated the
code ceases.
E 402 FUMES THERMOSTAT
u_02 code active for 1 hour, or u_02 code
generated 3 times in 2 hours of operation.
Reset may be performed from the CCI/DDC (or from the S61 board
via menu 2, parameter 21). If codes u_02 and/or E_02 occur again,
contact authorised Potterton TAC.
E 405 HIGH AMBIENT TEMPERATURE
HIGH temperature detected by ambient
temperature sensor. Reset occurs automatically when the condition that generated the
code ceases.
E 406 LOW AMBIENT TEMPERATURE
LOW temperature detected by ambient
temperature sensor. Reset occurs automatically when the condition that generated the
code ceases.
u 407
HIGH CONDENSER INLET
TEMPERATURE HIGH temperature detected by condenser inlet
temperature sensor or fumes sensor. Reset occurs automatically when the condition that generated the
code ceases.
E 407
HIGH CONDENSER INLET
TEMPERATURE u_07 code active for 1 hour, or u_07 code
generated 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 Potterton 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 Potterton TAC.
u 410 INSUFFICIENT HOT WATER FLOW
Insuffi cient water fl ow (the circulator is on and
the fl owmeter measure a low water fl ow).
Reset occurs automatically when correct water fl 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
Potterton TAC.
u 411
INSUFFICIENT ROTATION OF OIL
PRESSURE PUMP
Insuffi 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
Potterton TAC.
u 412 FLAME CONTROL UNIT ARREST Failure to ignite burner.
Reset occurs automatically when the solenoid valve opens again
(new ignition attempt), or if the code persists 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
Potterton 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
Potterton TAC.
E 417
COLD INLET WATER TEMPERATURE
SENSOR DEFECTIVE Fault (interruption or short circuit) on inlet 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
Potterton TAC.
E 420
CONDENSER INLET TEMPERATURE
SENSOR DEFECTIVE Fault (interruption or short circuit) on condenser
inlet 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
Potterton TAC.
E 422 WATER FLOWMETER FAULT Water fl owmeter fault
Reset may be performed from the CCI/DDC (or from the S61 board
via menu 2, parameter 21). If the code persists, contact authorised
Potterton TAC.
E 423 AIR/GAS MIXTURE SENSOR FAULT Air gas mixture sensor fault
Reset may be performed from the CCI/DDC (or from the S61 board
via menu 2, parameter 21). If the code persists, contact authorised
Potterton TAC.
E 424
FUMES TEMPERATURE SENSOR
FAULT
Fumes temperature sensor fault
Reset may be performed from the CCI/DDC (or from the S61 board
via menu 2, parameter 21). If the code persists, contact authorised
Potterton TAC.
E 428
GAS SOLENOID VALVE EXCITED
DURING FLAME CONTROLLER
ARREST The fl ame controller is arrested (E_12) but the gas
solenoid valve is excited. In this case the fl ame
controller is de-excited (E_12 resets). Reset may be performed from the CCI/DDC (or from the S61 board
via menu 2, parameter 21). If the code persists, contact authorised
Potterton TAC.
u 429
