| 摘要 |
The invention concerns a heating, ventilating and/or air conditioning device comprising at least one mobile element (3, 4,...) whereof the displacement is controlled by a single-pole motor (M1, M2...) powered by a control device (COM). The invention is characterised in that the control device has an input (E1) for receiving a temperature signal and/or an input (E2) for receiving a signal representing the voltage of a powering battery (BAT) and it has at least an output (S1, S2,...) to generate a frequency (F) monitoring the single-pole motor (M1, M2,) which depends on the level of at least one said signal. The monitoring frequency (F) can have at least two discrete values for at least two ranges of temperature and/or voltage level.
