FAQs:
Q: The MountainAir EC Whisper Fan is supplied with a dial speed controller. What is the advantage of using a MountainAir Environmental Controller?
A: While the dial speed controller allows you to manually adjust the fan’s speed, the MountainAir Environmental Controller will monitor the temperature within the growing environment, and automatically adjust the fan speed to maintain a target temperature pre-set by the grower. It’s a 3-mode controller, enabling you to select:
- Manual adjustment of the fan speed to achieve the ideal rate of air change
- Automatic thermostatic adjustment of the fan speed to maintain a target temperature
- Automatic shutdown of the fan if the temperature falls below a temperature threshold
