“EsYs” Errors aND bloCkING CoDEs
To unlock the system:
• Press “RESET” on the screen.
• If the fault reoccurs, contact your installer.
lIst of error codes + solutIons
[in error mode]
If a fault occurs during operation, the system locks out and the screen starts to
flash.
The first character is an “E” and flashes, the following two characters indicate
the code for this fault, see the chart below.
codes
description of the fault
solution for the fault
E 01
No flame presence after five start-up attempts
1. Check the wiring (short circuit in the 24 V wiring)
2. Check the electrode and its position
3. Check the burner gas level
E 02
Abnormal flame signal detected
1. Check the ignition wiring
2. Check the electrode and its position
3. Replace the ESYS (water damage)
E 03
Maximum thermostat open
Check the link across 9-10. Check the thermostat and wiring if fitted.
T1 or T2 > 110°C
1. Check the NTC wiring and replace it if necessary.
2. If the NTC1 sensor is OK, check if there is water flow in the boiler
E 05
No tachometer signal from the fan
1. Check the PWM connection
2. Check the fan’s wiring
3. If the problem persists after two “RESET” attempts, replace the fan,
if not, replace the “ESYS” circuit board.
E 07
Flue gas temperature too high (NTC5)
1. Check the connection of the NTC5 sensor
2. Check the wiring of the NTC5 sensor
3. If the problem persists replace the NTC5 sensor
E 08
No flame detection
1. Check the electrode gap
2. Check the electrode resistance [1kΩ]
E 09
Gas valve relay error
If the problem persists after two “RESET” attempts, Replace the “ESYS”
circuit board if necessary
E 11
Crack of sensor NTC1 or NTC2
Check the sensor NTC1 and NTC2
E 13
Remote “RESET” error
1. Do a local “RESET” on the boiler.
2. If the problem persists replace the “ESYS” circuit board
E 21
ADC error
“RESET” the system or Replace the “ESYS” circuit board if necessary
E 25
CRC Error
“RESET” the system or replace the “ESYS” circuit board if necessary
E 30
Short circuit NTC1
1. Check the connection of the NTC1 sensor
2. Check the wiring of the NTC1 sensor
3. If the problem persists replace the NTC1 sensor
E 31
NTC1 open circuit
1. Check the connection of the NTC1 sensor
2. Check the wiring of the NTC1 sensor
3. If the problem persists replace the NTC1 sensor
E 32
Short circuit NTC3
1. Check the connection of the NTC3 sensor
2. Check the wiring of the NTC3 sensor
3. If the problem persists replace the NTC3 sensor
E 33
NTC3 open circuit
1. Check the connection of the NTC3 sensor
2. Check the wiring of the NTC3 sensor
3. If the problem persists replace the NTC3 sensor
E 34
Deviation of the mains frequency > 1.5 Hz
Check the mains frequency
E 37
Water pressure
Check the water pressure
E
41
No communication from the water pressure sensor
Check the water pressure sensor and replace if necessary
