 Technical Data  

  Features  

◆Programmable Timer Function

This thermostat provide 7days programmable funciton,6perios yeach day you can setting the target time and temperature.Help you enjoy 

comfort and energy saving.

◆Child Lock Function

You can press up and down button to lock/unock your thermostat

◆ Flame-Retardant PC+ABS Housing

The thermostat shell is molded from PC+ABS flame-retardant material, meeting fire safety standards for wall-mounted electrical devices in 

residential and commercial buildings.

◆Ultra-Slim Design — 86×86×13.3mm

At just 13.3mm thick, this thermostat sits nearly flush against the wall surface. The compact 86×86mm footprint fits standard pattress 

boxes in most countries without wall modifications.

◆ Premium Acrylic Face Plate with Chrome Frame

The scratch-resistant acrylic front panel resists yellowing over time, while the polished chrome border adds a modern, elegant finish that 

elevates any room's interior design.

◆Large Backlit LCD Display with Adjustable Brightness

The high-contrast LCD screen features configurable backlight brightness (1–100 levels), ensuring clear visibility in full darkness or direct 

sunlight. All key information — room temperature, floor temperature, set temperature, time, mode, WiFi status, and lock indicator — is visible at a glance.

◆Feather Touch Capacitive Control Panel

Smooth glass-like capacitive touch buttons with no mechanical moving parts — silent operation, no dust-trapping button gaps, no click 

wear over years of daily use.

◆±1°C High-Precision Temperature Accuracy

Equipped with an NTC3977 10K thermistor sensor, the thermostat maintains your set temperature within ±1°C, eliminating the wide 

temperature swings typical of mechanical thermostats.

 FAQ

1.Can you ODM functions for us?

Yes.MOQ500PCS 

2.Can you OEM for us?

Yes.We can.MOQ500PCS  

3. Can I use both the internal and external sensor at the same time?

Yes — many thermostats offer a dual-sensor "ALL" mode where both the internal air sensor and external floor sensor work together. The thermostat reads the floor temperature for safety limits while using the air temperature for comfort control. This is the default recommended mode for electric heating.

4. How do I calibrate my thermostat if the displayed temperature is wrong?

Enter the configuration menu (usually by long-pressing a button for 7 seconds while powered off), locate the calibration setting (Function No. 1), and adjust from -9°C to +9°C. For example, if the thermostat displays 22°C but the actual room is 21°C, set calibration to -1°C.

5. What is "dead zone" or "switching differential"?

The dead zone (also called hysteresis or differential) is the temperature gap between when the heating turns off and when it turns back on. For example, with a set point of 22°C and a dead zone of 1°C: heating stops at 22°C and restarts at 21°C. A smaller dead zone gives tighter comfort but more frequent cycling; a larger value reduces cycling at the cost of slight temperature variation.

6. Can the thermostat work on both 110V and 220V power supplies?

Yes, thermostats with a 95–240 VAC, 50/60 Hz power specification work on any mains voltage worldwide — covering 100V (Japan), 110–120V (North America), and 220–240V (Europe, Asia, Africa). No transformer or voltage converter is needed.
