4. ຄໍາແນະນໍາການດໍາເນີນງານ
The Honeywell Home CT51N thermostat features simple manual controls for temperature and fan operation.
4.1 System Switch (Heat/Off/Cool)
- ຄວາມຮ້ອນ: Select this setting for heating operation. The system will turn on when the room temperature falls below your set temperature.
- ປິດ: This setting turns off both heating and cooling systems.
- ເຢັນ: Select this setting for cooling operation. The system will turn on when the room temperature rises above your set temperature.
4.2 Fan Switch (Auto/On)
- ອັດຕະໂນມັດ: In this setting, the fan runs only when the heating or cooling system is actively operating. This is the most common and energy-efficient setting.
- ເປີດ: In this setting, the fan runs continuously, regardless of whether the heating or cooling system is actively operating. This can help with air circulation.
4.3 ການຕັ້ງຄ່າອຸນຫະພູມ
Adjust the temperature slider to your desired temperature. The thermostat will maintain the room temperature at this setting based on the selected system mode (Heat or Cool).
