PANASONIC Panasonic A2W Heat Pump Aquarea K T-CAP, 3ph, 16 kW, Hydromodule – WH-SXC16K9E8

Description
Air-to-water heat pump for heating, domestic hot water preparation, and cooling (cooling mode can be activated via settings), consisting of an outdoor unit and an indoor unit (combi-hydro module), which is a combination of a hydro module and a hot water tank.

Indoor unit
Particularly compact housing made of galvanized and stove-enameled sheet steel, color: white, with an almost square footprint (500 x 348 mm) and low height (892 mm). The front can be completely removed for full access to the internal components. Unit is floor-mounted, leveled by height-adjustable feet. Separate sheet steel control box with its own hinged door for electrical connections, located inside the housing on the front. Control unit accessible without opening the housing. All sensor readings can be retrieved via the control unit, 2 x CN-CNT connections, MODBUS and Cloud Adapter can be connected.

Hydraulic circuit
Stainless steel plate heat exchanger. Circulating pump as a Panasonic high-efficiency pump with DC motor, continuously controlled. Flow monitoring. Vortex flow meter for dynamic adjustment of the water flow rate depending on the specified temperature spread, integrated dirty water magnetic filter for the water circuit, electric heating element with thermal overcurrent release. Safety and ventilation valve, water pressure sensor for measuring system pressure. 10-liter expansion tank. 3-way valve for switching between hot water mode and heating or cooling mode. The maximum water outlet temperature at the combi-hydro module is 60 °C and is reached even at -10 °C outdoor temperature. The minimum water outlet temperature in cooling mode is 5 °C. Heating operation up to -20 °C, cooling operation up to +10 °C outdoor temperature possible. The maximum water temperature in the domestic hot water tank is 65 °C.

Connections
Connections for refrigerant lines as well as for flow and return (heating/cooling), cold water inlet and hot water outlet of the hot water tank are routed upwards side-by-side from the unit.

Control
Modulating power adjustment of the compressor through INVERTER+ control electronics. Temperature sensors for outdoor temperature, compressor, hot gas and suction line temperature, and evaporator temperature. Higher efficiency, as the compressor starts in partial load operation and the compressor frequency is increased as needed, circuit reversal for rapid and efficient defrosting of the outdoor unit heat exchanger. Improved defrosting behavior through bypass defrosting. Communication modules for optimal data exchange with the hydro module. Electronic manometer provides value in electronic form for transmission via WLAN.

Optional board (CZ-NS5P) for additional functions:
• Control input for external on/off switching
• Control input for external room thermostat
• Control output for 2-way valve (cooling mode)
• Control output for 3-way valve (heating / domestic hot water)
• Interface for communication with the Aquarea Smart Cloud (CZ-TAW1B)

Electrical equipment:
• Auxiliary electric heater 9kW
• Thermal overload protection for auxiliary electric heater
• Residual current device
• Control inputs and outputs

System
The system is optimized for R32 refrigerant with low global warming potential. Functions include heating mode, cooling mode, screed drying, automatic mode, display of energy consumption and generation. Other functions: weekly timer, holiday programs, secondary pump control, bivalence control, optional control via outdoor temperature sensor or room temperature sensor/thermostat, intelligent quiet mode (quiet mode priority "Power"), optional board for additional functions such as control and temperature regulation of a buffer tank, control of two heating circuits (including swimming pool heating), input for external shutdown of the outdoor unit, integration of a solar station, external fault messages, inputs for SG-Ready control. Integration into third-party BMS systems via optional interfaces. Optional Smart Cloud adapter for operation and remote maintenance via Panasonic Cloud applications. Simultaneous use of the BMS system and the Smart Cloud adapter. Self-diagnosis system with display of error codes, improved defrost function, during defrosting operation the heat pump can switch to hot water mode.
Separate heating or domestic hot water control with a clear control panel (controller) with a backlit 3.5-inch display and keypad with touch buttons. Easy-to-understand symbols and plain text menu displays in 16 different user languages. Additional quick menu for the user. Continuous display of outdoor and flow temperature. Outdoor temperature-controlled adjustment of the flow temperature in heating mode. Temperature sensors for condenser, flow and return temperature. Weekly timer for time-dependent on/off switching and operating mode selection. Programmable timer for thermal disinfection. Demand-dependent control of the auxiliary electric heater.
