If the old module had a
vent damper connector but
a vent damper was not
installed, or if it did not
have a vent damper
connector, then connect
the 25V (2) or 24V wire
from the old module to the
TH-W terminal on the
S8610U. Do not use the
24V terminal on the
S8610U.
If the old module had a
vent damper, connect it to
the P1 connector on the
module, and wire the
terminals as indicated in
the table.
