•
HP/CON Option
= “HP” position (default) is for heat
pumps, and bridges Y and W1 terminals together.
When set to “CON” the Y and W1 terminals operate
independently for conventional systems.
•
B/O Option
= “B” setting (default) means the
shared B/O terminal is energized while in Heat
mode and off in Cool. “O” setting means the
shared B/O terminal is energized while in Cool
mode and off in Heat.

WIRING DIAGRAM NOTES:
For systems that only have one fan speed (only a single
“G” fan wire present), add a jumper wire (installer
provided) to bridge together “GH” and “GL”. Connect
your fan wire to either terminal after jumper wire has
been added.
For Conventional (cooling) applications, the options
below can be left per the factory defaults.
