Midea MH Kit – External Connection Kit for Hydraulic Modules

Midea MH Kit – External Connection Kit for Hydraulic Modules

The MH Kit is a smart addition to heat pump systems, specifically designed to optimize wiring between the hydraulic module and external components such as TBH, AHS, pumps and three-way valves. It enables shorter, more structured field wiring and increases installation flexibility, especially in complex heating systems or confined installation spaces.

Thanks to preconfigured connection ports and clearly defined communication interfaces, the MH Kit is an ideal solution for time-saving installation with reduced wiring errors. It is mounted vertically on the wall and comes with the required mounting accessories, making integration into existing systems easier.

The MH Kit also receives sensor data from temperature sensors such as T5, Tbt, Tw2, T1 and Tsolar and synchronizes them with the hydraulic module. If no valid sensor connection is available or communication with the main control board is lost, an automatic fault diagnosis such as an EL fault is triggered.

Benefits of the Midea MH Kit

• Simpler installation: significantly reduces cable lengths in the field and ensures structured wiring.
• Compatible with Arctic & Nature Series: supports both M Thermal Arctic and Nature Series via standardized interfaces.
• Integrated fault management: automatically detects communication failures and sensor issues and displays them on the unit.
• Comprehensive connection options: numerous ports for pumps, valves, temperature sensors, Smart Grid, electric heaters and more.
• Flexible installation: wall mounting with supplied accessories; space-saving and robust.
