This document describes the Electronic Energy Saving Timer Switch T-319, a device designed to control the power supply to appliances, helping to save energy.
Function Description
The Electronic Energy Saving Timer Switch T-319 allows users to set specific on/off times for connected appliances, thereby managing power consumption. It supports various timing modes, including continuous intervals, daily intervals, and countdown functions. The device is particularly useful for controlling appliances that do not need to be powered continuously, such as lights, fans, or other household electronics. By automating the power supply, it helps prevent unnecessary energy waste.
The device features a clear display that shows the current time and programmed settings. It includes buttons for setting the hour, minute, and various timing cycles, as well as a confirm button to save settings. An alarm function is also integrated, which can be activated to provide audible notifications. Additionally, it has a button lock feature to prevent accidental changes to the settings. The "Always ON" mode allows the device to continuously supply power, bypassing any programmed timing.
Important Technical Specifications
The Electronic Energy Saving Timer Switch T-319 has the following key technical specifications:
- Rated Voltage: 120V
- Rated Current: 15A
- Max. Frequency: 60Hz
- Max. Power Output: 1800W
- Standby Power Consumption: ≤0.5W
These specifications indicate that the device is suitable for most standard household appliances within the specified power limits. The low standby power consumption ensures that the device itself does not consume significant energy when not actively controlling an appliance.
Usage Features
The device offers several usage features and modes to cater to different scheduling needs:
Precautions
Before using the device, it's important to note that the sum of the power output of the appliances used with the timer switch should not exceed the specified power rating of the timer switch. This could lead to the timer switch burning or even causing a fire. Users must check the specified Voltage and Load for their specified timer switch model. The device is designed for indoor environment use only.
If the display shows "too low," "functions," or "symbols," it may indicate a power supply issue or a fault in the display. The timer needs to be plugged into a power socket to charge it.
Clock Setting
To set the current time:
- Press and hold the Confirm button until the numbers start flashing (around 3 seconds).
- Press the Hour or Minute buttons to adjust the time.
- Press the Confirm button to save the setting.
Daily Timing
This mode allows setting specific on/off times for daily operation. For example, to have the device turn on at 09:00 and off at 15:30 each day:

- Use the Hour and Minute buttons to set the desired ON time (e.g., 09:00).
- Press the Timing Cycle button again to set the OFF time (e.g., 15:30).
- Press the Confirm button to save the settings.
If a number is not displayed, it means there has either been a setting error or that there is a conflict between the set time periods. If you wish to set more than one period, do not press the Confirm button after setting the time. Instead, press the Timed button and you will be able to set a second or even a third period of times. You will see a 2 or 3 in the bottom left of the display. Press the Confirm button when you have finished setting your timed periods.
Countdown and Turn Off
This feature allows the device to turn off after a set duration. For example, to turn off after 30 minutes:

- Press the Confirm button to start the countdown.
When setting a countdown, you can also set an alarm that will sound when the countdown has ended. To set an alarm, press the Confirm and Minute buttons at the same time. An alarm bell symbol will appear on the right of the display. To remove the alarm, press the Confirm and Minute buttons together again.
Note: When the countdown has ended, the screen is flashing.
- Press the Confirm button, the countdown function will operate again.
- Adjust the countdown time and confirm it.
- Switch to another mode.
Countdown and Turn On
This feature allows the device to turn on after a set duration. For example, to turn on after 1 hour:

- Press the Confirm button to start the countdown.
When setting a countdown, you can also set an alarm that will sound when the countdown has ended. To set an alarm, press the Confirm and Minute buttons at the same time. An alarm bell symbol will appear on the right of the display. To remove the alarm, press the Confirm and Minute buttons together again.
