MountainAir EC Fan Speed Controller

The digital 3-mode environmental controller is made for use with the MountainAir EC Whisper Fans to provide users with total control. One mode allows for manual control of the fan’s speed, while two thermostat-controlled modes either turn off the fan, or reduce fan speed when the temperature of the room falls below set temperature.

Digital 3-mode environmental control thermostat allows:

• Manual fan speed control
• Fan on and off when used as heat extraction
• Adjust fan to desired speed when temperature falls below set temperature
