Midea M-Thermon A 10 kW Monobloc Air Source Heat Pump

The Midea M-Thermon A 10 (model MHC-V10W/D2N8-B2E30, code 14082174) is a monobloc air-to-water heat pump from the Arctic range, designed for heating and cooling in homes and small businesses with a thermal demand of around 10 kW (A7/W35). It features R-32 refrigerant, wired control, and WiFi connectivity for remote management and smart home integration.

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

Key Features

• Services: heating and cooling. DHW only with external tank.
• 100% water installation: only hydraulic supply/return (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.
• Smart Grid Ready and cascade operation without special control.
• USB Setup: fast parameterization and diagnostics via USB port.
• 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.
