The XK-W1088 dual digital thermostat is a compact and reliable solution for precise temperature control in two independent zones, powered by 220 VAC. The module is equipped with a dual LED display, with red display for channel 1 and blue display for channel 2, providing a clear and intuitive real-time view of parameters. Each channel uses a sealed NTC 10K sensor, with a cable of approximately 1 meter, suitable for humid environments or low-temperature underwater applications.
The measurement accuracy is ±1°C, with a resolution of 0.1°C, over a range of -50 ~ 120°C, making it suitable for a wide range of industrial and hobby applications. Each channel has a 10A relay with direct output, allowing direct connection of loads such as heating elements, fans, pumps, or heaters. The module supports two operating modes, heating and cooling, automatically detected based on the relationship between the start and stop temperatures. Settings are configurable from the front buttons and are retained in non-volatile memory after power-off.
Additional functions include configurable start delay between 0 and 60 minutes for each channel, high and low temperature alarms, as well as individual sensor reading correction.
Note: The enclosure is shared with the 12V, 24V, and 220VAC versions. The internal module is identified by a check mark applied with a marker on the enclosure.
Warning! This module operates at 220VAC mains voltage, which can cause severe electric shock or death if handled improperly or installed by unqualified personnel.

Usage:
Setting start and stop temperatures
Start: Briefly press the UP button for the corresponding channel to display the start temperature. Hold the UP button for 3 seconds until the digits flash, then adjust with UP / DOWN.
Stop: Briefly press the DOWN button to display the stop temperature. Hold the DOWN button for 3 seconds until the digits flash, then adjust with UP / DOWN.
Select heating / cooling mode
The module automatically detects the operating mode
Heating: If the start temperature (Start) < stop temperature (Stop)
Cooling: If the start temperature (Start) > stop temperature (Stop)
Delays and alarms
Press UP for channel 1 and UP for channel 2 simultaneously for 3 seconds. "P0" appears on the display. Navigate with UP1 and adjust values with UP2 / DOWN2.
| Code | Function | Range | Default |
|---|---|---|---|
| P0 | Channel 1 start delay | 0–60 minutes | 0 |
| P1 | Channel 2 start delay | 0–60 minutes | 0 |
| P2 | High temperature alarm | P3 ~ 120°C | 120°C |
| P3 | Low temperature alarm | -55°C ~ P2 | -55°C |
To exit the menu, wait a few seconds without pressing any button.
Sensor value correction
If the sensor displays a value slightly different from a reference thermometer, press UP and DOWN simultaneously for the corresponding channel for 3 seconds. "0.0" appears on the display. Adjust the value with UP/DOWN.
Factory reset
With the module powered, press DOWN for channel 1 and DOWN for channel 2 simultaneously for 3 seconds. "888" appears on the display, after which the module will enter normal operating mode.
