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
What is a Differential?
This control is made to specifically control a single variable speed fan motor. If you have a fan system with motorized intakes and/or multiple fans, they will need their own separate thermostat.
The difference between on and off setpoints on a control. For temperature, it is the difference in degrees between the thermostat's on and off setting. If you set a heating thermostat with a 3 degree differential to 71°, it will supply power at any temperature below 71° and cut off at 74° (3 degrees above the setpoint). A cooling thermostat would cut on above 71° and off at 68°.
