While the device is a popular, cost-effective solution for hobbyists and small-scale EV battery builders, the manufacturer often provides a sparse, poorly translated pamphlet. This article serves as the for the XH-M608. We will cover everything from pinout configurations and wiring diagrams to advanced parameter settings and common error codes.
Use ADD or DEC to cycle through P0 to P3 .
: Acts as an inline automated switch for your charging source or output load. Wiring Instructions Xh-m608 Manual
| Code | Meaning | Typical Range | |------|------------------------|------------------------| | P0 | Set temperature (SP) | -50 to +120°C | | P1 | Hysteresis (differential) | 0.1–15°C | | P2 | Control mode (heating/cooling) | H (heat) / C (cool) | | P3 | Calibration offset | -10 to +10°C | | P4 | Delay start (compressor protection) | 0–10 min | | P5 | High temperature alarm limit | up to 120°C | | P6 | Low temperature alarm limit | down to -50°C |
The XH-M608 uses a simple three-button interface: , ADD , and DEC . Parameter Menu (P0 - P3) Short press SET to cycle through the main menu options: Description P0 Mode Selection While the device is a popular, cost-effective solution
Ensure your battery connections are secure and that the wires are thick enough to handle the current without causing a significant voltage drop.
Often used to prevent deep discharge, the relay will disconnect the load if the voltage falls below the user-defined safety threshold. Common Applications Use ADD or DEC to cycle through P0 to P3
Sets the trigger for stopping a charge or starting a discharge.
You can view the currently set lower limit by short-pressing ADD and the upper limit by short-pressing DEC from the main display.
The is not a single authoritative document but a collection of minimal factory inserts, community-written guides, and generic PID controller instructions. It is essential for configuring temperature setpoints, hysteresis, and heating/cooling modes, but often lacks critical details like sensor beta values, error codes, and safe wiring practices.
