The outside temp is optional. It will allow you to set the balance point thru the thermostat that determines when the aux heat will run with the compressor shut off. Any thermostat designed for a heat pump will work.

The pluses of the Aiprilaire is that it is modular and has ability to add zones, multiple temp and humidity readings. You can control a whole house humidifier and the biggest plus is the ability to control it from a home automation system.
