The Giacomini R586RY113 pump assembly is designed for heating and air conditioning systems with a single zone, in applications where the circulation pump is already present or installed separately. It includes the R297 mixing valve, compatible with motorized actuators, making it ideal for smart installations with precise thermal control. It provides an efficient solution for underfloor heating, fan coil units, or hybrid applications with variable temperature, where a high-performance and flexible mixing valve is required. General features:

• R297 mixing valve, motorized (Kv = 10)
• Pump not included – allows integration into a system with an external pump
• Built-in fixed bypass (for constant recirculation)
• Can be equipped with KLIMAbus actuators (K275Y002 / 011 / 013)
• Optional installation of differential bypass (R284Y021)
• Includes check valve and thermometers at inlet and return

Product components:

• R297 mixing valve (manual or motorized)
• Shut-off valves with thermometers (inlet and return)
• Metal spacers with integrated control valve
• Rigid EPP insulation shell (density 35 kg/m³)
• Metal wall mounting base

Operation:

• Temperature adjustment capability with compatible actuator (optional)
• Manual bypass for constant recirculation, integrated into the R297 valve
• Operates effectively in automated thermal control systems (e.g., KLIMAbus)
• Reverse connection of inlet and return through insulation installation

Technical data:

• Fluids: water or glycol solutions (max. 50%)
• Temperature range: 5 – 100 °C
• Maximum operating pressure: 10 bar
• Kv valve: 10
• Weight: 4.9 kg (without pump)
• Connections: G 1-1/2”M (boiler) and G 1”F (system)
• Distance between inlet and return: 125 mm

Recommended applications:

• Low-temperature underfloor heating
• Cooling with fan coil units
• Combined systems with different temperature requirements
• Smart installations with 0–10 V control or 3-point actuator

Estimated covered area:

• The estimated area depends on the selected pump
• With compatible DAB EVOSTA2 70/180 pump:
  • Up to 400 m² for underfloor heating (50 W/m²)
  • Up to 200 m² for fan coil unit systems (100 W/m²)

Installation instructions:

• Wall mounting with suitable screws (not included)
• Connections: G 1”F (system outlet) and G 1-1/2”M (boiler inlet)
• The reverse connection of inlet and return is made through insulation and valve arrangement
• The mixing valve can be equipped with a compatible actuator (not included)
• It is recommended to inspect connections and seals annually
