## Description

Compact solution for precise temperature control in two independent zones, 12V power supply, dual red-blue LED display for quick monitoring, 2 included waterproof NTC 10K sensors for measurement in humid environments, range -50 to 120C with 0.1C resolution, two 10A relay outputs for direct control of heating or cooling.
The XK-W1088 dual digital thermostat is a temperature controller with two independent channels, each with its own LED display, its own NTC probe, and its own relay with direct output. It can control heating or cooling in two different zones, for example a heating element and a fan, two pumps, or two heaters. The module is suitable for incubators, aquariums, greenhouses, cold rooms, water tanks, and other systems that require temperature maintenance.
Each channel uses a sealed NTC 10K probe, with a cable of approximately 1 m, suitable for humid environments or immersion. Temperature is displayed with 0.1 °C resolution, with an accuracy of ±1 °C, and the measurement range is from -50 to 120 °C. For each channel, a start temperature and a stop temperature are set, and the operating mode is detected automatically. If the start temperature is lower than the stop temperature, the channel works as a heating thermostat. If it is higher, the channel works as a cooling thermostat. The menu also allows a 0 - 60 minute start delay for each channel, high and low temperature alarms, and individual correction of each probe reading.
Main features include the two LED displays (red for channel 1 and blue for channel 2), the OUT1 and OUT2 indicators that show relay status, four front buttons for setup, two 10 A relays with direct output, two NTC 10K probes, the buzzer for alarms, and non-volatile memory that retains settings after power-off. The module is powered by 12 VDC through the red (+) and black (-) wires. Since the output is direct, the input voltage appears on the yellow wire when the relay is closed, so 12 VDC loads do not need a separate power supply. The relays are rated at 10 A, but for long-term use a current of no more than 5 A per channel is recommended.
The module operates independently, without a development board and without programming, is adjusted from the front buttons, and directly controls 12 VDC loads. The enclosure is common for the 12 V, 24 V, and 220 VAC versions, and the internal module is indicated by a check mark applied with a marker on the enclosure.

Use:
Before connecting, check the mark on the enclosure and make sure the 12 V version is indicated, since the same enclosure is also used for the 24 V and 220 VAC versions.
Power the module with 12 VDC, with the red wire to positive and the black wire to negative, observing polarity. Do not apply a voltage higher than that indicated on the enclosure.
Connect each 12 VDC load between one yellow wire and one black output wire. Use only 12 VDC loads, since the direct output supplies the module’s input voltage.
Size the power supply for the sum of the currents of both loads and do not exceed 5 A per channel in continuous operation.
Insert the probes into the areas to be measured. The probes are sealed, and the cable is approximately 1 m long.
To set the start temperature (Start), briefly press the channel UP button to display it, then hold it for 3 seconds until the digits flash and adjust the value with UP and DOWN.
To set the stop temperature (Stop), briefly press the channel DOWN button to display it, then hold it for 3 seconds until the digits flash and adjust the value with UP and DOWN.
Select the operating mode by the relationship between the two values. For heating, set Start lower than Stop, and for cooling, set Start higher than Stop.
For delays and alarms, press channel 1 UP and channel 2 UP simultaneously for 3 seconds, until P0 appears. Navigate with UP1 and adjust values with UP2 and DOWN2. To exit the menu, wait a few seconds without pressing any button.

If a probe shows a slightly different value compared to a reference thermometer, press the UP and DOWN buttons of that channel simultaneously for 3 seconds. The display will show 0.0, and the correction value can be adjusted with UP and DOWN.
To restore factory settings, with the module powered, press channel 1 DOWN and channel 2 DOWN simultaneously for 3 seconds. The display will show 888, and the module will enter normal operating mode.
Settings are stored in memory even after power is turned off.
