The combine station is designed for boilers with a single radiant zone.Radiant mixing zone with the radiant zone pumpLoad valve keeps a minimum of 130°F - 55°C inlet temperatureGrundfos High-Efficiency Pump with ECM technologyHigh-temperature baseboard, radiator or fancoil connectionsThermal storage connectionsRequired by most manufacturers to keep a valid warrantyMade for 220V 60Hz installationConnections: 1" FPTWater for the heating system is mixed in a 3-way mixing valve with electronic control. Return water temperature to the boiler is kept at the min. The temperature of 55°C by the load valve. Boiler heat surplus is stored in a thermal store or a high-temperature zone such as a radiator, baseboard or fancoil. The heating output is controlled by an external controller through the actuated mixing valve.Made in Europe
