6.7. Boiler Burnout Detection
6.7.1. No Fuel
If during automatic operation the boiler outlet water temperature remains below the F08 setting
for a period of time set in the F09 setting, then the Controller considers the boiler as “burned out” and
enters the AL13 alarm condition.
6.7.2. Sudden Drop of Outlet Water Temperature
If during automatic operation the boiler outlet water temperature drops by 10°C, and during that
dropping period the temperature does not rise by 4°C, then the CH and HUW pumps are switched off, and
the Controller goes into the burnout detection mode.
The Controller waits for the period of time set in the F10 setting, during which it checks whether a rise of
4°C occurs.
If YES, then the burnout detection condition is stopped, and the CH and HUW pumps (if necessary) are
started.
If NOT, this means that the furnace is burned out the Controller enters the AL13 alarm condition.
6.8. Maximum Feeder Temperature Detection
The GH10RA Controller is equipped with an additional option of protecting from temperature rise in
the fuel feeder above the permissible value to prevent backfires into the fuel feeder.
The detection is active only in the automatic boiler operation mode (AUTO, MAINTAIN).
When the measured temperature exceeds the value set in the F14 service setting, the fuel feeder activates
for the period of time set in the F16 service setting to eject the ignited fuel from the feeder. During the F16
period the fan remains stopped.
When the time set in F15 service setting elapses, the Controller restores the maximum feeder temperature
detection process.
When the feeder T > 90°C, then fan is stopped, the fuel feeder is started for a period of 2xF16, and the
display indicates the alarm condition AL11 – “Maximum feeder temperature exceeded”. (section 6.5
page 10).
The Controller remains in the alarm condition until user response.
IF F14=0, THEN FEEDER SENSOR OPERATION IS OFF AND THE FUNCTION
OF FEEDER MAX. TEMPERATURE INCREASE DETECTION IS NOT ACTIVE.
