Page 14: Error Codes And Troubleshooting
First steps 1. No light at the remote control – burner doesn’t start Check the 12 V of the power supply. Check the fuse (2 AT) in the power cord, which is inside the heater close to the control. 2. Green LED of the remote control is burning – burner doesn’t start Check the water flow. - Page 15 Continuously flame out for 15 Gas supply system： source of supply times Safety (temperature) switch Detection system： safety defect temperature switch Ventilator, air pressure switch -check the supply voltage (APS), air flow blocked or - Is the ventilator running smooth, or do operating voltage too low failure you hear any scratching noise ? - check for dirt or water in the flow...
- Page 16 Failure E6: Defect temperature sensor or overheating E6 is for shorted hot water sensor or hot water over 85°. Please check, if the display shows the current outlet water temperature and the temperature rises to 85°C. Possible reasons: 85° can be normally only be reached, if somebody is “playing” with a real low water flow (up and down) or the water flow is “pulsing”.

Page 18: Hidden Function Mode
Hidden function mode (service mode) To enter laboratory / maintenance mode 1. Power on, water heater standby. 2. Adjust the temperature to 47°C 3. Press and hold “ON/OFF KEY” (green) for > 3 sec. 4. Adjust the temperature to 39°C 5. -
Page 19: Special Mounting Hints
Special mounting hints 1. Gas connection line The gas connection line is fixed inside the housing to the gas valve with a cap nut and a counter nut. For the installation insert the outer connection (from inside) through the hole at the backside of the outer housing. - Page 20 2. Water flow sensor For removing the sensor, just pull the 2 clamps, which are shown on the photo below. For mounting again, be sure, that the pipes are completely inserted in the sensor, before fixing the clamps.
