MASTER – Inverter monoblock heat pump
MASTER is a high efficiency reversible air to water heat pump. It is a fully integrated unit, where the indoor and outdoor units are combined as one module. This unit does not require refrigerant piping work since the monoblock outdoor unit is connected exclusively to water piping.
This unit does not require refrigerant piping work since the monoblock outdoor unit is connected exclusively to water piping.
It is equipped with DC inverter compressor, DC brushless fan motor, and hydronic kit with DC inverter circulator. The inverter technology together with the effective modulating power ensure very high efficiency. These features ensure high COP and EER.
All models have function of heating and cooling, can produce domestic hot water, are WiFi ready and can be controlled remotely. It is available in two versions: MASTER with R32 refrigerant, and MASTER PLUS with R290 refrigerant.

The MASTER heat pump is using R32 refrigerant, which has 70% lower GWP (global warming potential) compared to older types of refrigerant, and can reach output temperature up to 60°C.
The new range of heat pumps is available with R290 refrigerant, which is pure propane and has a very low environmental impact and can reach temperature up to 75°C. R290 is the preferred hydrocarbon alternative of the Environmental Protection Agency (EPA).
The heat pump is in compliance with ErP directives and attains the A+++ energy class.
Due to the full inverter technology of the compressor and fan, it can modulate to low frequency when set temperature is reached in order to maintain minimum heat losses of the house.
This ensures shorter heating time, smaller temperature fluctuations, and significant energy savings.
MITHSUBISHI COMPRESSOR
The compressor is the heart of the heat pump for efficiency and reliability. It ensures stable heating capacity and reduced noise.
All MASTER heat pumps come with DC inverter twin-rotary Mitsubishi compressor
DC BRUSHLESS FAN
The fan motor is DC brushless to ensure improved efficiency. Also, the fan blades and the air grill are specially designed to ensure as low noise as possbile.
EVI TECHNOLOGY
EVI stands for “Enhanced Vapor Injection” and is a technology used to achieve higher performance at lower temperatures as low as -25°C.
EEV EXPANSION VALVE
The expansion valve is with electric control (EEV). This feature, combined with precision measuring of refrigerant temperature and pressure, ensure optimum efficiency.
PLATE HEAT EXCHANGER
The plate heat exchanger is carefully selected to increase heat transfer efficiency, low pressure drop, and ensure higher COP.
DC INVERTER PUMP
The heat pump comes with reliable DC inverter pump, to ensure reliability and comfortable heating experience.
The heat pump is equipped with a 5 inch colour touch screen, which is very intuitive and user-friendly, and has shows the power consumption daily, monthly and yearly.
Premium design 5 inch colour LCD display
Capacitive touch button
Information with simple graphic icon and text
Energy consumption and heat production monitoring daily, monthly, yearly
Integrated control of a hot water boiler / buffer
Room thermostat connection for heating / cooling
Integrated weekly programmer
WiFi ready and control through smartphone application
Cascade of 2 heat pumps with standard controller, up to 8 heat pumps with a cascade module (optional)
Control of the complete heating installation with 7 sensors: external temperature, buffer tank, DHW tank (low and high), internal room sensor, solar circuit, heating circuit.
SG READY AND SMART GRID
The heat pump can receive signals about the power source and switch energy usage. When the electricity price is high, the heat pump runs as energy-saving as possible, when the price is low, it will use as much electricity as possible. It can also be connected with the solar photovoltaic installation, and adjust its power consumption to the energy production.
The heat pump has integrated Wi-Fi function and mobile application, so that the user can control the heat pump anywhere and anytime.
The application has highly integrated control functions, is easy to operate and transforms your heating installation into a truly smart operating system. Additionally, the producer can use the smart data platform to provide remote product inspection, and even software update, offering prompt assistance.
