Flue Gas Temperature Management -AIR Heaters-

The heater automatically adjusts the power based on the flue gas temperature according to the following logic:

1. Flue gas temperature < 100 °C
   If the flue gas temperature drops below the minimum threshold of 100 °C (Parameter 51 = 100 °C, “combustion threshold”), the heater automatically increases the power every 5 minutes until the threshold is reached.
2. Flue gas temperature = 100 °C
   If the flue gas temperature is equal to 100 °C, the heater maintains the current power without any variation.
3. Flue gas temperature > 100 °C
   If the flue gas temperature exceeds 100 °C and reaches 120 °C (preset delta of 20 °C, not adjustable), the heater automatically returns to the initially set power, preventing overheating.
