Fan Speed Controllers
The day/night fan speed controller automatically slows down or speeds up centrifugal fans to meet user-selected day and night temperature set points between 55–95°F, allowing for a much tighter and precise temperature curve.
It can drive single-phase 115V induction motor fans up to 750 W, and its temperature sensor features a 6' cord and is precise to 2°F/1°C. The multimode controller functions identically and also allows you to select a minimum fan idle speed between 25% and 60% of full power in 5% increments.
Also features an emergency stop that can be activated during the day or night only, or all the time. Both include user guide and mounting kit. Three-year warranty.
