WIRING DIAGRAM NOTES (APPLIES TO ALL DRAWINGS)

*The DASHED lines are optional depending upon your system type.

*Verify whether “C”, “X” or “B” wires are connected to system common.

*If “B” and “O” are both present, it is likely that “B” is a system common.

*If a “B” wire in your system is a common, then connecting it to the “B” terminal may cause damage to your system.

*If “Y” and “C” are both present, it is likely that “C” is a system common.

*Use an optional common wire to allow the system to power your thermostat.
