I have a carrier infinity ics gas furnace with a vennmar hrv he 1.3. I just had the carrier inifinity controller installed, and noticed after the cooling call the blower shuts down as well. After 5 minutes it starts up again. The hrv was and still is interlock to this furnace

Not sure what your asking.

The installation may require a NIM or Network Interface Module.

It provides Y, G , R and B.

These are probably standard furnace signals, but not sure.


Just not sure. Not enough info in Carrier's datasheets. They like you to use their products.
