Typically the float switch is wired in series with the yellow wire from the
stat.

As the furnace uses the condensate pump for heating, it could also be wired
in series with RH/RC.

yes, I have that too. how is that typically wired, I assume in the
thermostat wire between the thermostat and the control board of the
furnace/air handler? I guess I would need an ice cube even to make that
work as I have a high efficiency furnace, humidifier, and central air
all sharing one condensate pump.
