Fuel feeder temperature detection
The GH21TA controller has the additional option to protect against temperature in the fuel
feeder tray rising above the permitted level, preventing the flame from heating the fuel.
Fuel feeder temperature detection works in automatic mode the boiler (Automatic,
maintain, alarm). When the temperature measurement exceeds that set in parameter S14, the
fuel feeder activates for the duration set in parameter S16, in order to remove lit fuel from the
feeder. The fan is turned off for the duration of the time set in S16.
When the time set in parameter S15 expires, the controller regains control of the maximum
feeder temperature.
