Note – in 2016 Invisco started shipping the U.S.Motors EC motors with a different speed control input connection. The new motors use a red wire as the speed control voltage input. So pin 8 goes to the red wire. 

For motors shipped in 2015 here are the instructions.

24 vac to 1 AND 2 – use the wire connected to 1 as a common wire that will be the wire for speed control back to the motor white or (-) input.

Wire another wire from 8 back to the motor speed control black or (+) input. 

When your home is hot – over 80 degrees or more, SmartSpeed(TM) starts your whole house fan on at high speed for maximum cooling. Then as the temperature drops, the fan speed (and input power) drops until it is turned off. Unlike other thermostats, SmartSpeed(TM) does NOT turn your whole house fan on. Only you can do that, either at home or by remote control through either a local wireless AC power switch OR by your smart phone using off the shelf AC remote switches. 

The speed control has a list price of $195.
