Midea M-Thermon A 16 kW Monobloc Air Source Heat Pump

The Midea M-Thermon A 16 (model MHC-V16W/D2N8-B2E30, code 14082177) is a monobloc air-to-water heat pump designed for heating and cooling in large homes and small buildings with thermal demands close to 16 kW (A7/W35). It features R-32 refrigerant, wired control, WiFi connectivity, and compatibility with zoning systems (Airzone, Acuazone) and BMS.

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

Key Features

• Services: heating and cooling. DHW only with external tank.
• 100% water installation: only hydraulic supply and return (no gas 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 for power modulation.
• USB Setup: fast parameterization and diagnostics via USB port.
• Zoning and BMS: Native Modbus RTU; BACnet/KNX via gateway.
• CTE 2020 / CYPE: considered a renewable solution and included in the CYPE database.

Recommended Applications

Large single-family homes, multi-family homes with several zones, and small commercial buildings. The 100% water monobloc design reduces paperwork and speeds up commissioning thanks to USB configuration.

Installation and Maintenance

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