5. Awọn ilana Iṣiṣẹ
The Carrier HH18HA280 Temperature Actuation Switch operates automatically based on the temperature it senses. It does not require manual adjustment or user interaction during normal operation.
- The switch monitors the temperature of its environment.
- Upon reaching a pre-set temperature threshold, the switch will change its state (e.g., open or close a circuit).
- This change in state signals other components in the HVAC system to perform a specific action, such as turning a fan on/off or activating a heating/cooling element.
Ensure the switch is free from obstructions and debris that could affect its temperature sensing capabilities.
6. Itọju
