DDC, install room sensor close to unit's return air
stream, use four (4) conductor cable and rout to
connect sensor to controller's R-net port as shown
on unit wiring diagram.
Although the images of this document are a good
representation of the unit electrical layout the
installer must refer to the DDC and unit wiring
diagrams as the ultimate guide for electrical
reference. This installation shall be performed by a
