The XH-W1219 Dual LED Digital Thermostat Temperature Controller regulates thermal levels in hardware like incubators or cooling rigs. This module switches a 10A relay based on real-time data from an NTC10K waterproof sensor. A -50 to 110°C control range handles extreme environments.
Key Features
- Dual LED Display: Three-digit red and blue screens show current and target values. Monitoring set points requires no button toggling.
- 0.1°C Control Precision: High-resolution logic manages small temperature fluctuations. This maintains tight hysteresis settings for sensitive hardware.
- 10A Relay Output: Mechanical switch handles resistive loads at 12V DC. It triggers heaters or fans during sudden load shedding.
- Waterproof NTC Probe: 0.5-meter sensor cable resists liquid penetration. The 10K thermistor works inside humid incubator parts in Bangladesh.
- 0.5s Refresh Rate: High-speed sampling updates the display twice every second. Fast response prevents thermal overrun in rapid-heat systems.
Frequently Asked Questions
How to calibrate XH-W1219 temperature?
Enter the P4 parameter setting by holding the SET button. Adjust the offset value to align with a reference thermometer.
What is the difference between W1209 and W1219?
The W1219 includes a secondary LED display for the set point. Both actual and target values appear together without switching modes.
What happens if the sensor is disconnected?
The display shows 'LLL' and the relay disconnects the load immediately. This safety mechanism prevents uncontrolled heating or cooling during sensor failure.
