- Flash Fast: rapid blinking.
- Heartbeat: Constant 1/2 second bright, 1/2 second dim cycles.
- A single flash code number signifies that the LED flashes X
times at 2 Hz, remains off for two seconds, and then repeats the
sequence.
- X + Y flash codes signify that the LED flashes X times at 2 Hz,
remains off for two seconds, flashes Y times at 2Hz, remains off for
three seconds, and then repeats the sequence.

* Important
If the old module had a vent damper connec-
tor 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.
TH-W
If the old module had a vent damper, connect
it to the P1 connector on the module, and
wire the terminals as indicated in Table 1.
