Power the module by connecting a 12V DC power source to and V- . Connect NTC thermistors to the designated input channels

: For distances exceeding 2 meters, use shielded twisted-pair (STP) cables to protect weak analog thermistor signals from cross-talk and ambient electromagnetic interference (EMI). Modbus RTU Communication Protocol

Most NT18B07 units come pre-set for a (Monday–Friday same program, Saturday–Sunday same program). To change the setpoints:

Here’s how to set up the NT18B07 with popular platforms:

Prevents users from accidentally setting the target temperature too low. Temperature Calibration -7.0°C to +7.0°C Read the Docs Setup and Integration Hardware Connection:

To ensure stable operation and mitigate data corruption caused by electromagnetic interference (EMI), follow these wiring protocols carefully: 1. Power Supply Connection
