PREHEATING MANAGEMENT
In addition to the post-heating, the CTRL-DPH control is able to manage an electric preheating system (operated by a PWM signal or on-off)
to prevent the formation of ice inside the heat exchanger. The control automatically activates the anti-frost procedure when the temperature
measured by the expulsion probe (Tx) drops below the value of 3 °C. Here the heater is powered at the minimum power. If the temperature Tx
continues to decrease and falls below 1 °C, the feed of the preheater is progressively increased until it reaches 100%. When Tx returns above
3 °C the procedure is interrupted. The temperature values 3C° and 1C° are set at the factory and can be modified on request. The preheating
status is shown in the main window.
