Model A4: Fan is operating at FP16 It begins counting time FP6 and FP7. Upon expiry of FP6 the heater turns off and goes to Mode A5. If '-' is pressed, A4 Mode is displayed in the lower display and time to FP6 is counted down in the upper display. If '-' and 'SET' are pressed, FP:06 is displayed in the lower display, and FP4 parameter value is displayed in the upper display. By entering into this Mode, monitoring of possible flame loss commences. If flame is absent over 4 minutes, the heater turns on and control unit goes to Mode A3. Model A5: Feeder screw work / not work to FP9 parameter. Fan is operating at FP16 Upon expiry of FP7 control unit goes to Mode P5. 20
If '-' is pressed, A4 Mode is displayed in the lower display and time to FP7 is counted down in the upper display. If '-' and 'SET' are pressed, FP:07 is displayed in the lower display, and FP7 parameter value is displayed in the upper display. Mode P1 to P5 Fan works at speed: FP18-FP22 (P1-P5) Feeder screw work / not work by FP10-FP16 (P1-P5) If a Tset move in mode A7 Mode A7 Screw is turned off. Sub-Mode 1: Fan operates at speed at FP17. Counting down of time 180s If this time expires or flame extinguishes (10s+5s) before time expires, it goes to sub-mode 2. Sub-Mode 2: Fan operates at maximum speed until 90s and then goes to sub-mode 3. Sub-Mode 3: If temperature drops to T set -FP24, it goes to Mode A0. 8.7. Burner operation Operation in summer regime : a) With sanitary water tank (next to the tank) 8.8. Extinction phase After reaching set temperature of the boiler, the burner starts extinction phase in manual operation it is done by pressing ON/OFF button, in automatic extinction it is done in accordance with set activating times and when errors E4, E5 and E6 occur. In the beginning of extinction phase, pellet feeding is stopped, OFF appears in the lower display, and current boiler temperature appears in the upper display, fan works all the time the flame in burner is detected by the photo-cell (or max. 180 seconds). After that fan work for another 120 second to blow off the grate and prepare it for next firing. 8.9. Operation with timer Control unit can automatically switch on and off the burner according to set weekly and daily programmes. Precondition for proper functioning of the burner with timer is correctly set current time and day of a week. Three turns on and three turns off can be planned per day of a week. All activating times are factory set to off. For turning on of activating time see Setting of the burner operating parameters. 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. 8.10. 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
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. 8.11. 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
10. Firing 10.1. 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 10.2. Switching off The burner will stop if you press key START/STOP for 3 seconds. 10.3. Further ignitions The burner turns on after 4-5 minutes after holding down key START/STOP for 3 seconds. 23
