Controls

Signature Series Self-Contained Units

We’ve redesigned the self-contained unit with the latest control technology to make it even better! New modular DDC controls with human interface (HI) panel make self-contained units more flexible and easier to operate.

Controls areTrane-designed to work with Trane equipment for optimum efficiency. The factory installs and commissions each control component to ensure simple and reliable operation.

Furthermore, the DDC control’s modular design allows greater application flexibility using up to twelve different modules, dependent upon unit options. You can order exactly what the job requires as options, instead of one large control package. And since unit features are distributed among multiple printed circuit boards, field replacement is easy.

Depending upon unit options, IntelliPak® units can operate as:

1)stand-alone

2)interface withTrane’sTracer® building management system

3)interface with a generic (non-Trane) building management system.
