Maximum feeder temperature detection
The GH10PA Controller is equipped with an additional option protecting it from fuel feeder temperature
rise above the permissible value to prevent backfires into the fuel feeder.
The detection is active in the automatic boiler operation mode (AUTO, MAINTAIN, ALARM).

period the fan remains inactive.
When the time set in
F15
service setting elapses, the Controller restores the maximum feeder temperature
detection process.
When the feeder T exceeds 90°C the fan is deactivated, the fuel feeder is activated for a period of 2x
F16
, and
the display indicates the alarm condition
AL11 – “Maximum feeder temperature exceeded”
.
(
section 6.5

The Controller remains in the alarm condition until user response.
IF F14=0, THEN FEEDER SENSOR OPERATION IS DISABLED AND THE
MAXIMUM FEEDER TEMPERATURE DETECTION FUNCTION IS NOT
ACTIVE.
