Timer Mode allows you to schedule up to 12 periods, each with its own target temperature and humidity range. This is perfect for day/night cycles or specific growth stages requiring varied conditions.

4.3 Cycle Mode
Cycle Mode automates the device to cycle on and off based on a countdown timer. This is useful for intermittent operation of equipment, such as ventilation fans or humidifiers.

4.4 Manual Mode
Manual Mode provides simple one-touch operation for immediate on/off switching of connected devices. This mode offers direct control when specific automation is not required.

5. App Control & Monitoring
The mobile application provides comprehensive control and monitoring capabilities for your LTC-318-W controller.
5.1 Remote Control and Adjustments
Once paired, you can remotely view current temperature and humidity readings, change operating modes, and adjust settings from anywhere with an internet connection.
5.2 Data Tracking and Export
The app allows you to track environmental changes over time, offering 1 year of cloud-based data viewing and unlimited local data export. This feature is crucial for analyzing trends and optimizing your environment.
5.3 Alerts and Notifications
Set up custom alerts to receive instant notifications on your mobile device if temperature or humidity levels go outside your preset ranges. The device also features a buzzer alarm for immediate local alerts.

6. Maintenance
6.1 Probe Care
