Midea M-Thermon A 6 kW Monobloc Air Source Heat Pump

The Midea M-Thermon A 6 (model MHC-V6W/D2N8-B2E30, code 14082172) is a monobloc air source heat pump from the Arctic range, designed for heating and cooling in homes and small commercial spaces with moderate thermal demand. It features R-32 refrigerant, wired control, and WiFi connectivity for remote management.

Important: The unit does not autonomously produce DHW (domestic hot water); to have DHW in the installation, an external tank/indirect tank is essential (not included), along with the corresponding hydraulic and control accessories.

Key Features

• Services: heating and cooling. DHW only with external tank.
• 100% water installation: only hydraulic connections to the outdoor unit (no refrigerant handling).
• High temperature supply: water up to 65 °C with +5 °C outdoor; up to 60 °C with −15 °C.
• Connectivity: WiFi (MSmartLife app), compatible with Amazon Alexa and Google Assistant.
• Cascade operation without special control to modulate power in multi-unit installations.
• Smart Grid Ready and USB Setup for fast parameterization and diagnostics.
• Zoning and BMS: compatible with Airzone/Acuazone; native Modbus RTU (BACnet/KNX via gateway).
• CTE 2020 / CYPE: considered renewable and listed in the CYPE database.

• Safety elements: safety valve, check valve, air vents, sanitary expansion vessel if needed.
• Thermostatic mixing valve to limit consumption temperature.
• Secondary circulator if required by the system hydraulics.

Recommended Applications

Well-insulated single-family homes, apartments, or commercial spaces with a thermal demand around 6 kW to 7 kW (A7/W35). The 100% water monobloc design simplifies regulatory compliance and reduces commissioning time thanks to USB configuration.

Installation and Maintenance

• Hydraulic supply/return connections; no refrigerant handling required.
• Maintain service distances, level and anti-vibration support.
• Size inertia and hydraulic balancing according to minimum flow/volume.
• Check wiring sections and protections according to the indicated maximum current.
