For proper and efficient burner operation minimum burner work time is 1 hour, and min. stand-by time between two activating times is 1 minute Boiler overheating protection The control unit has a built-in protection which protects boiler against overheating. Regardless the operating regime (either winter or summer) and regardless the needs, the control unit turns on circulation pumps to cool the boiler. 21

22 In winter and summer regimes, if the boiler temperature exceeds 93 C, and regardless heating or sanitary water is needed, the boiler pump and/or sanitary water pump turns on and works until the boiler temperature drops below 93 C Flame extinction during operation 9. Errors Regardless the current operating regime of the burner, if errors E1, E2, E7 and E8 occur, the control unit will stop operation immediately, while in case of errors E4, E5 and E6 burner goes to extinction phase. If control unit is in firing phase and flame has not occurred yet, due to notification on error, supply, fan and heater will be stopped immediately. In case of error Err appears in the upper display and error type appear appears in the lower display and if it is also necessary to carryout extinction phase (in case of E4, E5 and E6 errors) Err appears in the upper display and OFF and error type appear alternately in the lower display. Oznake greški: - E1 safety pressure switch, feeding tube overheating - E2 firing safety time expired - E4 excessive temperature on feeding tube - E5 sanitary water temperature sensor - E6 flame disappeared - E7 error in memory - E8 interruption in fan operation - E9 not used! - E10 backfilling supply tube with pellets E e4 To enable control unit to resume to normal operation, error must be corrected and cancel it on the control unit. Error is cancelled by simultaneous pressing WINTER and SUMMER buttons and ''+'' button. If the error cause is not repaired, error cannot be cancelled. 22

23 10. Firing First ignition This operation must be carried on only by professional skilled people Procedure: 1. The fuel pellet tank must be full ( this operation must be done by the final user); 2. Connect electrical panel to electrical supply and make sure that the display is switched ON; 3. Switch off the programming and start up the feed screw, keep it pressed until the complete filling of the feed screw (to establish the feed screw filling it is enough to verify that the pellets flow down from the feed screw pipe to the burner). When the feed screw is filled up leave the key 4. Select the use for SUMMER mode; 5. Start settings to change selected settings follow the indicated procedures; 6. Leave settings by pressing SET key; 7. Press key START/STOP; 8. The ignition will start in 4-5 minutes; 9. When the burner is turned on you have to check that : - The heating generator arrives to the temperature - The circulator system works correctly - In winter mode every radiator must be the same temperature SET FUEL FEEDING SETTINGS IN ACCORDANCE WITH HEATING GENERATOR POWER CALIBRATION OF THE RELATION BETWEEN COMBUSTIVE AIR /FUEL TO PROMOTE CORRECT COMBUSTION AND OBTAIN A RESULT AT LEAST EQUAL TO THE MINIMUM NORMS IN FORCE CHECK THAT ALL REGULATIONS AND SECURITY SYSTEMS WORK CORRECTLY CHECK THAT THE EVACUATION PIPE OF THE COMBUSTION PRODUCTS WORKS CORRECTLY CHECK THAT, AT THE END OF ALL SETTINGS OPERATIONS, THAT ALL SETTINGS SYSTEMS WILL BE BLOCKED AND CLOSED Switching off The burner will stop if you press key START/STOP for 3 seconds Further ignitions The burner turns on after 4-5 minutes after holding down key START/STOP for 3 seconds. 23
