Product Name(s): Tracer Loop Controller
Product Description: The Tracer Loop Controller (TLC) is a configurable direct digital controller that provides control and monitoring for water-source heat pump systems. System components that can be controlled and monitored included the pump, boiler, tower (open or closed circuit) mixing valve and the individual heat pumps. The TLC can be used for the coordination of geothermal water-source heat pump systems.
Product Application(s): In a communicating system the TLC has the ability to provide features such as automatic heat pump alarming, centralized water-source heat pump reset, loop water temperature optimization, and building freeze protection.

Programming Method(s) Template based through local display
Resident vs Non-Resident Program Execution Resident
Resident/Supervisory. This controller supervises the scheduling of other controllers.
Resident/Stand Alone. This controller contains its own schedule.
Non-Resident. This controller is dependent upon another controller for its schedule.
None. This controller has no scheduling features.
Resident Energy Management
Energy management algorithms for this controller can be custom programmed
Pre-programmed/built-in algorithms available, and are fully editable using custom programming
Pre-Programmed/built-in with limited editing via template-based programming
Controller is not typically used for energy management functions
