Description:
1. This product is an upgraded version of W3230 temperature control.2. Compared with the previous generation, the upgrade is as follows
1 degree Celsius (°C) and Fahrenheit (°F) can be measured and displayed (W3230 can only display measurement °C)
2 increase the buzzer (Buzzer), can send an audible buzzer alarm (W3230 no buzzer)
3 red and blue bi-color indicator light indicates the output mode at the same time, red is the heating mode (heat), blue is the cooling mode (Cool) (W3230 is a single red indicator, only the output can be indicated)

Indicating situation |
|
Red |
The red light flashes and the heating mode is delayed.；The red light is always on, heating mode is running. |
|
Blue |
Blue light flashes, cooling mode delay starts； The blue light is always on ,cooling mode is running. |
1. Short press “SET” small digital tube to flash, press “△” or “▽” to set the target temperature, press “Standby” button or no operation to save the setting within 3 seconds.
2. Press and hold “SET” to enter the code setting mode, press “△” or “▽” to switch the code. After selecting, press “SET” to enter the code setting. After setting, press “Standby” button or no operation to save the setting within 3 seconds. .
3. The last parameter setting is saved by default after shutdown.
4, restore the factory settings: press and hold "SET" to power on.
5. When the module is powered on, it will start directly. After power-on, press and hold the “standby” button, the module will enter “sleep” or “wake up”; in case of power failure, the module will run automatically after power recovery, no need to start manually.
**The working power supply voltage must be connected according to the standard voltage of the label, otherwise the module will be damaged easily.
