XY-WT01 Digital Thermostat Switch
Features:
Set Temperature --Set T; Backlash Temperature--Back T
1. Heating Mode H：
When Temperature ≤ Set T – Back T; Relay conduction, heating equipment begin to work;
when temperature ≥ Set T, Relay disconnect, heating equipment stop work;
2. Refrigeration mode C：
When Temperature ≥ Set T+Back T; Relay conduction, refrigeration equipment begin to work;
When Temperature ≤ Set T; Relay conduction, refrigeration equipment stop work;
3. High-Temperature Alarm ALA：
When Temperature ≥ Alarm Temperature, The system opens the sound and light alarm and
disconnects the relay, any key stops the sound light;
4. Delay Start OPH：
When a normal heating or refrigeration work is done, the system starts to time T, and only after
the T≥OPH, the system can carry out the next round of heating or refrigeration work;
5. Temperature Correction Function OFE(-10.0 ~ 10.0℃)：
The system will work for a long time and may have deviations that can be corrected by this
function, Temperature = Measured + Calibration；
6. Parameter Remote Read/Set：
The parameters such as setting temperature, backlash temperature, and temperature correction
can be set through UART.
7. Real-time Temperature Report:
If the temperature reporting function is turned on, the product is transmitted to the terminal by
the UART at 1s intervals, which facilitates data collection;
8. Relay enable (default enable):
If the relay is disabled, the relay remains disconnected;
9. Restore Factory Settings:
At the same time press the STOP, set key more than 3S, restore factory settings;
Working mode setting /backlash temperature :
1. In the running interface, short press SET key, enter the Quick setting interface;
2. After entering the Quick Setup interface, switch the parameters
3. Through the UP DOWN key, modify the parameter value, support short press/long press;
4. Long press SET to build more than 3S or continuous 6S without any key operation, exit quickly
set the interface, and save parameters;
Alarm temperature/Delay Start /temperature correction:
1. In the operating interface, long press SET more than 3s, enter the parameters to set the
interface;
2. Enter the parameter to set the interface, through the short press SET key to switch to set the
parameters;
3. Through the UP DOWN key, modify the parameter value, support short press/long press;
4. Long press SET3s above or continuous 6S without any key operation, exit parameter set
interface, and save parameters;
How to turn on high-temperature alarm (default off):
Enter the parameter setting interface, switch to the alarm parameter ALA, turn on or off the
high-temperature alarm function by short pressing the STOP button, and if the high-temperature
alarm function closes, ALA displays \'----\' as a reminder;
How to turn on delay start (default 0ff):
Enter parameter setting interface, switch to alarm parameter OPH, turn on or off
high-temperature alarm function by short Press STOP button if high-temperature alarm function
closes, OPH show \'---\' to remind;
