controller (or from the S61 board via menu 2, parameter 21). If the
code persists, contact authorised Technical Assistance.
u 410
INSUFFICIENT HOT WATER FLOW
Insufficient water flow (the circulator is on and
the flowmeter measure a low water flow).
Reset occurs automatically when correct water flow 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 controller (or from the S61 board
via menu 2, parameter 21). If the code persists, contact authorised
Technical Assistance.
u 411
INSUFFICIENT ROTATION OF OIL
PRESSURE PUMP
Insufficient 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 controller (or from the S61 board
via menu 2, parameter 21). If the code persists, contact authorised
Technical Assistance.
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 controller (or from the S61 board
via menu 2, parameter 20). If the code persists, contact authorised
Technical Assistance.
E 416
HOT OUTLET WATER TEMPERATURE
SENSOR DEFECTIVE
Fault (interruption or short circuit) on outlet hot
water temperature sensor.
Reset may be performed from the controller (or from the S61 board
via menu 2, parameter 21). If the code persists, contact authorised
Technical Assistance.
E 417
COLD INLET WATER TEMPERATURE
SENSOR DEFECTIVE
Fault (interruption or short circuit) on inlet water
temperature sensor.
Reset may be performed from the controller (or from the S61 board
via menu 2, parameter 21). If the code persists, contact authorised
Technical Assistance.
E 420
CONDENSER INLET TEMPERATURE
SENSOR DEFECTIVE
Fault (interruption or short circuit) on condenser
inlet temperature sensor.
Reset may be performed from the controller (or from the S61 board
via menu 2, parameter 21). If the code persists, contact authorised
Technical Assistance.
E 422
WATER FLOWMETER FAULT
Water flowmeter fault
Reset may be performed from the controller (or from the S61 board
via menu 2, parameter 21). If the code persists, contact authorised
Technical Assistance.
E 423

Air gas mixture sensor fault
Reset may be performed from the controller (or from the S61 board
via menu 2, parameter 21). If the code persists, contact authorised
Technical Assistance.
E 424
FUMES TEMPERATURE SENSOR
FAULT
Fumes temperature sensor fault
Reset may be performed from the controller (or from the S61 board
via menu 2, parameter 21). If the code persists, contact authorised
Technical Assistance.
E 425
