Need help?Do you have a question about the Atlantic Calypso FS 172L and is the answer not in the manual?
The device described in this manual is the Atlantic Calypso, an energy-efficient heat pump water heater designed for domestic hot water production. It is an unvented cylinder system, meaning it stores hot water at mains pressure, providing strong water flow to multiple outlets simultaneously. The Calypso series includes models with different capacities, such as the Calypso FS 172L and Calypso FS 210L, offering flexibility for various household needs.
The Calypso operates as a heat pump water heater, extracting heat from the ambient air and transferring it to the water stored in the cylinder. This process is significantly more energy-efficient than traditional electric water heaters, as it uses electricity primarily to move heat rather than generate it directly. The unit can be installed in various configurations, including those with ducted air connections to draw air from outside or from specific areas within the building, such as a garage or utility room, and discharge it to another location. It features an integrated electric booster for periods of high demand or when the heat pump alone cannot meet the required temperature. The system is designed to be compliant with BS EN 12897: 2016 standards.
The Calypso FS 172L and FS 210L models share several key specifications. Both have a maximum water supply pressure of 16 bar and a maximum inlet pressure (pressure regulator) of 3.0 bar. The maximum design pressure (expansion relief pressure) is 4.5 bar. The temperature and pressure relief valve is set at 6 bar. The integrated electric immersion heater has a power of 1600 W and a maximum temperature of 62°C. The over-heat thermostat operates at 80 +/-5°C.
For the Calypso FS 172L, the cylinder capacity is 172 litres, with a heat loss of 51 W and an expansion vessel size of 22 litres. The Calypso FS 210L has a cylinder capacity of 210 litres, a heat loss of 58 W, and an expansion vessel size of 22 litres. The air operating range (ducted configuration) for both models is -5 to 43°C, and the ambient air configuration is 5 to 43°C. The achievable hot water temperature via heat pump is 62°C. The maximum electrical power input (heat pump and immersion) is 650 + 1600 = 2250 W. The maximum thermal power output from the heat pump only at 45°C is 1345 W. Sound power level is 49 dB(A). Refrigerant used is R134a, with a charge of 0.85kg for the 172L and 0.86kg for the 210L. The air ducting method involves separate inlet and outlet to the exterior. The coefficient of performance (M profile, 7°C) is 2.78 for the 172L and 2.81 for the 210L. The energy efficiency (nwh) is 117.0% for the 172L and 118.4% for the 210L. Heating time from cold (10°C to 54°C) is 5h48 for the 172L and 7h18 for the 210L. Standing power input is 19 W for both. Maximum usable hot water volume (V40, EN16147/2017) is 228.0 litres for the 172L and 285.2 litres for the 210L. Pressure loss during test is 60.0 Pa for the 172L and 54.3 Pa for the 210L. Airflow during test is 387.0 m³/h for the 172L and 402.6 m³/h for the 210L. The coefficient of performance (L profile, 7°C) is 3.15 for the 172L and 3.02 for the 210L. The energy efficiency (nwh) is 129.40% for the 172L and 124.35% for the 210L. Heating time from cold (10°C to 54°C) is 5h44 for the 172L and 7h27 for the 210L. Standing power input is 17 W for the 172L and 20 W for the 210L. Maximum usable hot water volume (V40, EN16147/2017) is 227.0 litres for the 172L and 285.1 litres for the 210L. Pressure loss during test is 58 Pa for the 172L and 57 Pa for the 210L. Airflow during test is 386.0 m³/h for the 172L and 391.6 m³/h for the 210L. The electrical supply is 230V 50Hz +15%/-10%. IP rating is IPX1B. RCBO/MCB Type C is 16 Amp. The insulation thickness (cylinder body to case) is 63 mm.
The Calypso is designed for ease of use with a clear display and intuitive controls for setting operating modes and parameters. Users can select various heating modes, including anti-legionella cycles, advanced modes with backup, and electric booster options. The system allows for programming heating periods to optimize energy consumption, especially when connected to a photovoltaic system for self-consumption. The "Installation parameters" section details how to configure settings like date, time, language, and connectivity. The device can be combined with equipment using the io-homecontrol protocol for remote management. The manual emphasizes safety instructions, including proper handling during installation due to the unit's weight and the need for installation in a frost-free room with adequate ventilation. It also specifies minimum room volumes for installation to ensure proper air circulation for the heat pump.
Regular maintenance is crucial for the optimal performance and longevity of the Calypso water heater. The manual provides a service record section for tracking maintenance visits. User maintenance includes draining the water heater if it will be switched off for an extended period, closing the cold water supply, opening a hot water tap, and opening the safety unit drain valve. It also recommends checking the general condition of the appliance and looking for error codes or leaks monthly, and checking the cleanliness of the condensates discharge tube annually. Professional maintenance involves checking the ducting for proper installation and absence of crushing, ensuring the condensate drain pipe is clean, verifying electrical connections, and inspecting the electric booster. A refrigeration engineer should perform checks on the heat pump exchanger, heat pump elements, evaporator, and refrigerant every two years (or more frequently in dusty environments). The manual includes a troubleshooting guide with displayed error codes, their causes, consequences, and diagnostic/repair steps. It also lists other faults without error codes, such as no hot water or low flow rate, and provides possible causes and diagnostic/repair solutions. The manual stresses that only original manufacturer's spare parts should be used and that any electrical work must be performed by a specialist. It also provides a detailed diagram of the device's components for maintenance and repair purposes, including the front cover, compressor condenser, compressor, air inlet probe, fitted rear housing, evaporator, upper and lower evaporator probes, fan, volute assembly, control panel, electronic regulation, ECS regulation probe, thermal safety, heating element, and plastic housing.
