Contractor #1 installed 2) Carrier FE4 infinity fan coils.
The low voltage saftey of the condensate pumps are not tied in (I found out when the 2nd floor flooded last summer)
Fired #1 (no insurance), units installed and up and running

Contractor #2, Hired him to come in and check the charge on the units and check over the install, $900.00 later, and He does not se how the condensate low voltage can tie into the FE4's Board.

Contractor #3 - he does not know.

So how does the Condensate low voltage "cutout" tie into the Infinity system. I have all the manuals (tech and owner)
and it never mentions the condensate pump ??
