Nt18b07 Manual [upd] Jun 2026
Supports up to 7 simultaneous NTC sensor connections (compatible with B3950 10K 1% thermistors).
If it says "Model: NT18B07," continue reading. The information below is tailored to the most common variant: the 18-inch LED-backlit LCD TV.
If you’ve lost the paper manual for your NT18B07 series thermostat (common in many HVAC replacements or generic installs), getting it programmed can be tricky because the interface is minimal.
Understanding the MODBUS implementation is crucial for developers and integrators. nt18b07 manual
A dedicated 2-pin white plug-in terminal for the NTC probe. 2. Wiring Diagrams for Common Applications
Use high-quality 10K NTC Waterproof Probes . If the sensors are located far from the module, use shielded twisted-pair cables to prevent interference.
Connect a DC power supply between 6V and 24V to the VCC and GND terminals on the module. It is strongly recommended to use a clean, dedicated power source. Supports up to 7 simultaneous NTC sensor connections
Connect the directly to the Neutral wire of your heater . 3. Programming and Parameter Settings
Typically measures from -20°C to +125°C with a 1% accuracy level when used with standard NTC sensors.
The device is set to the wrong input source. Solution (from the manual): If you’ve lost the paper manual for your
Ensure the NTC sensor used is 10K B3950. A 1% sensor is recommended for accuracy.
The (often associated with the LC12S wireless module) is a serial communication component commonly used in RFID systems and wireless data transmission .
A research project from the 5th International Conference on Agricultural Engineering (AESAP 2023) successfully used the NT18B07 to build a low-cost IoT data logger for monitoring palm sugar drying. The system used an ESP32 to access the seven temperature channels from the NT18B07 and convert the MODBUS RTU protocol into the MQTT format, which was then sent to the Adafruit IO cloud platform and recorded in a Google Sheet. The system achieved a measurement accuracy and precision level of over 99%, showing the NT18B07 is well-suited for industrial IoT applications.
To communicate with the module, you'll need to connect the NT18B07's A(+), B(-), and GND terminals to the corresponding RS485 interface on your host device (e.g., a USB-to-RS485 adapter, a PLC's RS485 port, or an ESP32/Arduino with a MAX485 module). The connections are:
