  • Page 69: Controls

    New modular DDC controls with human interface (HI) panel make self-contained units more flexible and easier to operate. Controls are Trane-designed to work with Trane equipment for optimum efficiency. The factory installs and commissions each control component to ensure simple and reliable operation.
  • Page 70 This information can be edited only if certain options are field- installed or deleted from the unit. For example, if a Trane communication interface (TCI) module or ventilation override module (VOM) were field- installed, the unit configuration will require editing to reflect those options for proper unit operation.

  • Page 71: Sequence Of Operation

    If more than one VOM sequence is being requested, the sequence with the highest priority is initiated first. Priority schedule PKG-PRC002-EN Controls is that sequence “A” (unit off) is first, with sequence “E” (purge with duct pressure control) last.
  • Page 72 The generic building automation system module (GBAS) provides broad control capabilities for building automation ® systems other than Trane’s Tracer system. A field provided potentiometer or a 0-5 vdc signal can be applied to any of the inputs of the GBAS to provide the following inputs and outputs.
