E05.7-2 No gas
• Full load speed at the burner HA1 not reached
 Possibly voltage supply disturbed

E05.8-1 No gas
• Full load speed at the burner SG not reached
 PWM signal interrupted

E05.8-2 No gas
• Full load speed at the burner SG not reached
 Possibly voltage supply disturbed
 
E05.9-1 No gas
(only 20.10 / 20.20)
• Full load speed at the burner HA2 not reached
 PWM signal interrupted
 
E05.9-2 No gas
(only 20.10 / 20.20)
• Full load speed at the burner HA2 not reached
 Possibly voltage supply disturbed
 
E05.10 No gas
(from software 4.15)
Wait 20 seconds, if
there is no “Flame
OK” or “Alarm
Signal”
• Interruption of Flame OK or Alarm Signal between
flame controller - control module HA1.
Check connection between FA and CM / GM:
CM (Control Module): for OGS 6.10 to OGS 12.20:
X14:1/2 and X15:12 (for appliances without GM)
GM (Gas Module): Plug X20:5/6 and X25:10
FA (Flame Controller): Terminals 1, 2, 5
 
E05.11 No gas
(from software 4.15)
Wait 20 seconds, if
there is no “Flame
OK” or “Alarm
Signal”
• Interruption of Flame OK or Alarm signal between
flame controller - SG control.
Check connection between FA and GM:
GM (Gas Module): Plug X21:4/5 and X25:11
FA (Flame Controller): Terminals 1, 2, 5
 
E05.12 No gas
(from software 4.15)
Wait 20 seconds, if
there is no “Flame
OK” or “Alarm
Signal”
• Interruption of Flame OK or Alarm signal between
flame controller - control module HA2.
Check connection between FA and GM:
GM (Gas Module): Plug X22:4/5 and X25:12
FA (Flame Controller): Terminals 1, 2, 5

(temperature on the
sensor >300°C)
• Hot air contactors do not switch off (burnt together)
• Motor not operating (e.g. because of 2 defective
microfuses F10, not with the 6.06 as F10 protects
the CM).
