1.0 Introduction
Our air handlers (AHUs) provide ducted heating and cooling, combining with other appliances to
satisfy most HVAC requirements. In addition, the AHU offers support for humidifiers and dehumidifiers
to prevent bacteria or mold. And for ease of use and operation, IBC delivers the AHU with pre-
programmed settings for each model. If customizing is required, HVAC professionals can download
the free IBCconnect app to program the air handler (see Operating the air handler using the
IBCconnect app on page 61).
We've illustrated the AHU's diverse applications below. To view corresponding wiring and
configuration instructions, see Installation on page 19.
