| General Purpose Unit Control
General purpose controllers provide the capability to tie Trane equipment without unit control modules and non-Trane equipment into the Trane communication network. Products include the Thermostat Control Module, Programmable Control Module, and the Universal Programmable Control Module. Thermostat Control Module The Thermostat Control Module (TCM) provides a basic yet powerful interface between Tracer Summit, Tracer 100 series, or Tracker systems and mechanical equipment. The TCM can extend the Integrated comfort system (ICS) technology to existing, auxiliary, and non-Trane equipment. The TCM communicates with a building controller over a single communication link. ICS Capability The TCM provides an interface between the building control panel and equipment not having Trane Unit Control Modules (UCMs), such as lighting, fans, and non-Trane unitary equipment normally operated by a standard thermostat. Software Capabilities The TCM can function either as a 2-stage heat/2-stage cool thermostat for air conditioning units and heat pumps, or as a provider of slave points for the building management panel. In thermostat mode, the TCM monitors its sensors and controls its outputs like a wall thermostat. The TCM can be configured as either a 2-stage heat/2-stage cool air conditioning thermostat or a heat pump thermostat. This control resides in the TCM, and the TCM can operate standalone (without the building management panel) during system startup or when there is a communication loss. In slave mode, the building controller monitors the TCM inputs and directly controls the TCM outputs. The TCM input and output points function as though they are hardwired, generic points on the building control panel. The building control panel provides control such as time of day scheduling and demand limiting. See the appropriate Building Control section of this catalog for details on each panel’s capabilities. Hardware Description Three versions of the TCM are available:
