Watts Tekmar Mixing Control 360

Mixing Control 360

The Mixing Control 360 is purpose-built to manage a mixing valve utilizing Outdoor Temperature Reset functionality. Its applications range from in-floor radiant heating to commercial baseboard systems, offering comprehensive Boiler Return Protection with full reset capability. This control ensures the regulation of a single heating water temperature through Mixing Outdoor Reset. It governs the mixing process by adjusting a floating action type mixing valve actuator (compatible with 3 or 4-way valves) and provides oversight of the mix system pump.

Key Features:

  • Outdoor temperature reset functionality optimizes heating performance in response to outdoor conditions
  • Optional indoor temperature feedback enhances control precision (requires indoor sensor)
  • Warm weather shutdown feature prevents unnecessary heating during warmer periods
  • Automatic boiler differential ensures efficient boiler operation
  • Floating action mixing control mechanism maintains temperature regulation
  • Powered mixing system pump output streamlines system management
  • Quick setup facilitates easy installation and programming
  • User comfort adjustment enables fine-tuning of building space temperatures
  • Advanced settings allow customization to meet specific building requirements
  • Test sequence functionality ensures proper component operation
  • Setback input promotes energy savings by adjusting heating levels
  • CSA C US certified, meeting applicable UL standards for safety and reliability.
