What is likely to happen if the power supply to the controller is faulty?

If the power supply to the controller is faulty, the watering schedules will not function. The controller relies on a consistent power source to operate its programming and ensure that it activates the watering system according to the scheduled times. A fault in the power supply means that the controller cannot operate effectively, which leads to a failure in executing the programmed watering tasks. Consequently, irrigation will either not occur at all or may function erratically, as the device cannot maintain the necessary operations without reliable power.

While error messages might be displayed if the controller has some operational capacity, they are not guaranteed. Additionally, the controller might not reset itself automatically if it does not receive adequate power. Likewise, sensors depend on the controller and should not stop working independently unless they too are affected by a lack of power. Thus, the core issue here is that a faulty power supply directly inhibits the controller's ability to execute its watering schedule.
