Notes:
1. Jumper “W2” to “W3” if three stages of indoor heat
are available
2. “Y” terminal must be connected at indoor unit for
cooling airflow
Sensor Options in the Installer Settings/Sensor Settings menu
Remote Sensor (connect to the RS terminals)
- None
- Replaces internal sensor
- Average with internal sensor
Outdoor Temp Sensor (connect to the ODT terminals)
- None
