Phason® MTC-4C Auto Variable Speed Fan Control

Replacement for Model MTC-3C unit.

The Modulating Temperature Control 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.
