Boiler working stages

3.1.7. GLW-OFF - STAGE

If GLW-OFF mode is enabled and conditions below are met, boiler enters GLW-OFF stage

-OFF

 - set the flue gas temperature for boiler shutdown when GLOW mode is enabled

- Flue gas temperature GLW

    (setting range: 80°C - 180°C)
    factory setting: 25 kW: 

°C; 35 kW: 

°C, 45 kW: 

°C

140

105

105

  - this condition is met if option is enabled and when measured flue gas temperature in D-2 stages is lower 
    than set flue gas temperature constantly for 900 sec (factory settings).

IMPORTAN NOTE: 
FACTORY SETTINGS (FLUE GAS TEMP. OFF AND FLUE GAS TEMP. GLW-OFF) ARE ONLY AS REFERENCE,
ACTUAL SETTING MUST BE ADJUSTED BY USER ACCORDING TOTHE FUEL USED AND BOILER FLUE 
GAS PASSAGES CONDITION (HOW CLEAN/DIRTY BOILER IS)

3.1.8. PF-XXXX - STAGE

After power supply failure and power supply return, boiler enters in one of possible stages. Boiler continues to work if 
power supply occurs in:
- S-stage (stabilisation)
- D-1/D-2 stage (work)
- PAU-stage(pause) and boiler has demand to work (boiler difference)

Boiler starts in the same way as when boiler starts after reaching demand from boiler diference (set boiler temp. - boiler 
difference) with C-stage (stabilisation)

Every working stage after power supply off/on has next to working stage name and designation, added designation of 
power supply failure/return ’’PF’’ (PF-xxxx)

- ’’PF’’ = power failure/power return
- ’’xxxx’’ = one of stages described above (for example PF-D2)
- Appears after a power off/power on in case of power supply failure
- The prefix "PF" disappears with new start of the boiler

3.1.9. ERR-OFF - STAGE

When  during  boiler  working  occurs  error  that  causes  boiler  to  stop  (OFF-stage),  boiler  enters  ERR-OFF  stage 
(indication that boiler has shut down because of error).

3.1.10. W4-OFF - STAGE

When warning W-04 occurs and boiler is waiting for conditions for flue gas fan to start, boiler enters W4-OFF-stage. 

3.1.11. XXXS1 - STAGE

If in S - stage (ignition) wasn't done 2nd pressing of OK button into the set time, the boiler working proces automaticaly 
enters C - stage (stabilisation stage) marked as CS1 and  every next stage has sufix ''S1'' (example: ''D-1 S1'').

If in some ''D-2 S1'' stages conditions for entering to OFF or GLW-OFF stage are fullfilled, on screen is shown OFFS1 or 
GLWOFFS1 and boiler stops (flue gas fan is off).
