MixiMizer automatically maintains indoor comfort as the outdoor temperature changes.

The Grundfos MixiMizer represents a real breakthrough in the efficiency and effectiveness of radiant floor heating. At the heart of the system is the outdoor Reset Control which ensures the heat supplied to the building is equal to the heat loss of the building. The Outdoor Reset Control continuously "fine-tunes" the indoor heating water temperature based on the changes in the outdoor temperature. When the outdoor temperature drops, additional hot water is automatically injected into the heating distribution system, so that the desired indoor temperature is maintained.

• Built-in integrated pump housing
• Corrosion resistant materials or coating on all internal water passages and external surfaces
• Built-in check valve to prevent thermal siphoning
• 2 Water Temperature Sensors: one for system water temperatures, one for boiler return water temperature (both factory-installed on the pump control)
• Outdoor Temperature Sensor: for accurate outdoor readings through a wide temperature range
• Selectable heating curve dial: used to select the precise heating curve for the building's design parameters
• Led Performance Panel: color LED readouts display power, call for heat, pump performance reduced and percentage of pump performance

Warm Weather Shutdown - disables the system when the outdoor temperature reaches 70F, for greater efficiency
Pump Exercising - if pump has not run for 3 days, the control exercises the pump for 10 seconds to ensure longevity and performance
External "Call for Heat" input - accepts external demand signal for heat, offering flexibility and simplicity of operation
Post Purge - after a call for heat is removed, the pump will run for 20 seconds to purge the remaining heat from the system
