FEATURES
In temperature control, the fan cools the home to the comfort temperature set, just like a home's thermostat. Overcooling and running the fan longer than needed are eliminated. Homeowner no longer has to get up at night to turn the timer off because it's too cold or extend the timer because the fan turned off too soon.
Optional Temperature Control
One concern with temperature control is that the following morning, the homeowner will forget the fan is on and close up windows. The built-in safety timer will automatically turn the fan off the following morning just in case the homeowner forgets. 
Built-In Safety Features
The iM3 WiFi App includes a 1 to 12 hour timer and optional temperature control.
