What you see here is a Homestead Geneva, equipped with HomeStar, which was Homestead's answer to Casablanca's Inteli-Touch, so basically a fan controlled by a microprocessor inside the motor housing, which is fed commands via a wall control which sends pulsed electrical signals through the house wires. It also includes several automatic programs. Now onto HomeStar vs. Inteli-Touch:
HomeStar is known to have a higher failure rate than Inteli-Touch due to the electronic components' high sensitivity to power surges and fluctuations.
The major improvement over Inteli-Touch, on the other hand is that HomeStar includes the ability to step down the fan speed and light brightness, whereas with Inteli-Touch, you would have to shut the fan/light off and start the process from low if you wanted to lower the fan speed or dim the lights down.
Another small improvement is the separate program button on HomeStar, where you can simply hold down the button until you reach the program you wish to activate rather than pushing the fan and light buttons in sequence to activate a similar program.
It's also worthy of note that although they are both made by Kontrust, Homestead HomeStar and Sierra Micro-Touch are NOT cross-compatible, meaning that a Sierra Micro-Touch (or NuTone SelecTouch) fan will not respond to a HomeStar wall control.
