Example: electric heater management
The defrost heater is managed as an auxiliary control function, and must be enabled. The control probe in this case is the fresh
air probe. The On/Off heater features “direct- heating” activation, with the trend shown in the fi gure, while for the modulating
heater, the action depends on the PID parameters.
