Phason Modulating Temperature Control (MTC-4C)


  • $ 27047

The Modulating Temperature Control (MTC-4C) allows you to automatically control ventilation fans according to the ambient temperature.

When the temperature is at or below the temperature set point, the MTC-4C operates the fans at the idle speed setting. When the temperature exceeds the temperature set point, the MTC-4C increases the speed. When temperature increases 6°F above the set point, the MTC-4C increases the speed to maximum.

When the temperature drops below the set point, the MTC-4C shuts off the fans (in shut-off mode) or operates the fans at the idle speed (idle mode).

Applications: Hog, Poultry, Dairy, Greenhouse or Light-Industrial Buildings
