PANASONIC Panasonic A/W heat pump Aquarea K T-CAP, 3ph, 16 kW, outdoor unit – WH-UXZ16KE8

Air/water heat pump in split design with impressed current anode

Description
Air/water heat pump for heating, domestic hot water preparation and cooling (cooling mode activatable by setting), 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-enamelled steel sheet, color: white, with an almost square footprint (602 x 599 mm) and low height (1642 mm). Front fully removable for full access to the unit components. Unit installation on the floor, leveling by means of height-adjustable feet. Separate control box made of steel sheet with its own hinged door for the electrical connections located inside the housing on the front. Control unit accessible without opening the housing.
All sensor readings can be accessed via the control unit, 2 x CN-CNT connections MODBUS and Cloud Adapter can be connected, energy and heat meters can be connected via MODBUS. Stainless steel hot water tank (EN material no. 1.4521), capacity 185 l, including stainless steel water heat exchanger, including impressed current anode and tank temperature sensor, insulation with U-Vacua thermal insulation and polystyrene, design pressure 10 bar

Hydraulic circuit
Stainless steel plate heat exchanger. Circulating pump as Panasonic high-efficiency pump with DC motor, continuously controlled. Flow monitoring. Vortex flow meter for dynamic adjustment of water flow depending on the specified temperature spread, integrated dirty water magnetic filter for the water circuit, electric heating element with thermal overcurrent release. Safety and vent 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 down to -10 °C outdoor temperature. The minimum water outlet temperature in cooling mode is 5 °C. Heating mode possible down to -20 °C, cooling mode up to +10 °C outdoor temperature. 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 from the unit in a single row.

Control
Modulating power adaptation of the compressor by INVERTER+ control electronics. Temperature sensors for outdoor temperature, compressor, hot gas and suction line temperature as well as evaporator temperature. Higher efficiency because 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 performance through bypass defrosting. Communication modules for optimal data exchange with the hydro module. Electronic pressure gauge 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:
• 9kW electric auxiliary heater
• Thermal overload protection for electric auxiliary heater
• RCD
• 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 "performance"), 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 defrost operation the heat pump can switch to hot water mode.
Separate heating and domestic hot water control with a clear control panel (controller) with backlit 3.5-inch display and keypad with touch keys. 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 adaptation 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 preselection. Programmable timer for thermal disinfection. Demand-dependent control of the electric auxiliary heater.

Compliance with EU directives
The device complies with the relevant EU directives and standards.
