AquaSnap^® - Water-sourced heat pump
61WG

General description

• Reduced footprint
• Scroll compressors and R-410A refrigerant
• Variable-flow pump
• Low-noise option (-3dB (A))
• Stacking of two units for increased capacity (up to size 090)
• Several communication protocols available: JBus, BacNet, MS/TP, LON
• Water connection at the top or rear

Optimized for Heating 

• High temperature up to +65 °C
• Evaporator temperature down to -5 °C
• Control of the three-way diverter valve for domestic hot water and space heating requirements
• System approach - the Heating System Manager maximizes the global efficiency of complex systems where the 61WG units are combined with an auxiliary heating source to serve multi-zone space heating and domestic hot water production
• Compatible with most heating systems, both in new and refurbished buildings and permits domestic hot water production (with a dedicated temperature setpoint)

Adaptability and simple installation

• Can be provided with several hydraulic module options, both on the evaporator and/or condenser side, with different levels of available pressure and variable or fixed-speed pumps
• Water side heating reversibility

SmartVu™ control

• Integrated advanced communication features
  • With hydraulic module: water pressure display and water flow calculation
  • Easy and high-speed communication technology over Ethernet (IP) to a building management system
• User-friendly and intuitive 4.3" color touch screen user interface
  • Access to multiple parameters
  • Concise and clear information available in local languages
  • Complete menu, customized for different customers
• Remote management (standard)
• Easily accessed from the internet

• Maintenance function (standard)
• Compulsory Maintenance Reminder - FGAS sealing check
• Configurable Periodic Maintenance Reminder
• Storage of user documents, electrical diagrams and spare parts

Advance control

• Optimized energy management
  • Patented auto-adaptative algorithm optimizing the condensing pressure at part load to reduce compressor load and ensure perfect supply for the evaporator with liquid refrigerant
  • Set-point reset based on the outside air temperature or the return water temperature
  • Master/slave control of two heat pumps operating in parallel
  • Two independent time schedules to control
  • Unit start/stop
  • Operation at a second chiller-water set-point
