Which of the following statements is false about how to start an electric heater?

Statement C is false because the electric heater's startup logic is not solely based on low temperature. It depends on the specific mode selected. For instance, in "Dehumidification heating" mode, the heater will only consider starting if the dehumidification function is active, regardless of how low the room temperature is. The other options (A, B, D) correctly describe the specific logic for each corresponding operational mode, where conditions other than just low temperature (like dehumidification status) are critical triggers.

A. This statement is true. In the combined mode, the heater activates if either dehumidification or low-temperature heating conditions are met, based on temperature requirements.

B. This statement is true. In "Dehumidification heating" mode, the heater's operation is contingent on the dehumidification function being enabled first.

D. This statement is true. In "Low temperature heating" mode, the heater's operation is based only on temperature, irrespective of the dehumidification function's status.
