NOTES
(APPLIES TO ALL
DRAWINGS)
* 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.
