Eco-King C140 Technical Bulletin

Technical Bulletin- C/H140 Nuisance Error 01 and 08
In certain cases, Eco King has found that the C/H140 Model boilers can produce nuisance Error 01 and 08 codes. Below is the
remedy for a manual calibration in order to resolve the nuisance errors.
A: Flame impedance and temperature value
B: Ladder symbol: calibration menu
C: Flame symbol: ignition. The unit burns
D: Speed (rpm/10)
E: Boiler capacity (%)
Manual Calibration Process
1. Start the Heating system or open the hot water faucets to create as much demand as possible.
2. Connect the flue gas analyzer to the appliance. It is preferred to measure the flue gases with mounted front cover. To enable
that, use an external sampling port in the vent system, just above the appliance. Or in case this point would not be available,
remove the flue gas sensor at the top of the heat exchanger and insert the probe.
Warning
Make sure the flue gas analyzer connection point is closed after performance of the calibration procedure. Failure to do so may
result in serious injury or death.
3. Simultaneously press [P2] and [P3] until the text 'test' appears in the display.
• The 'ladder' symbol flashes in the display.
• The fan speed (rpm) increases until the start speed is reached. The display shows the speed of the fan.
• The capacity of 100% flashes on the right in the display. 1 and 00 appear alternately in the display.
• The starter current is determined and the boiler ignites. The 'flame' symbol and the text 'ok' appear when the flame is stable.
