Modulating Temperature Control (MTC-4C)

Simple and effective temperature control

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

When the temperature is at the temperature set point, the MTC-4C operates the fans at the idle speed setting. When the temperature exceeds the set point, the MTC-4C increases the speed. When the 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).

The MTC-4C is ideal for poultry, livestock, greenhouse, or light-industrial buildings.
