Modulating Temperature Control

The Modulating Temperature Control allows you to automatically control the speed of fans with variable speed motors according to the ambient temperature.

• When the temperature is at the set point, fans operate at the idle speed setting.
• When the temperature exceeds the set point, it increases the fan speed.
• When the temperature increases 6°F above the set point, the fan speed will be at the 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).

Modulating Temperature Control features:

• Variable speed output
• Adjustable 40° to 90°F temperature range
• Temperature differential of 6°F
• Adjustable minimum idle speed
• Can handle 10 full load amps @120V
• One-foot temperature probe, extendable to 500 feet
• Rugged enclosure (corrosion resistant, water resistant, and fire retardant)
• For use with any of our variable speed fans
