Variable Speed, 4-20 mA, Mixing Control
The Mixing Control 365 is designed to operate a mixing device using outdoor temperature reset. It can be used in applications ranging from in-floor radiant to commercial baseboard systems for boiler protection with full reset. This control regulates a single heating water temperature through outdoor reset. It provides mixing by using a 4-20 mA output to control an analog mixing device such as a mixing valve or variable frequency drive, or a variable speed output to a 120 V pump. It can also control the mix system pump. The best replacement model will vary with your application. Contact tekmar customer service for assistance.
