[57] ABSTRACT
A temperature control system for use with a fluid circulating system operable in a heating or cooling state to monitor and control the temperature and flow of fluid circulated through a remote liquid circulation manifold comprising a display/control panel to select the system operating parameters and provide a visual indication of the system status including operating temperature and fluid flow and a micro control including logic circuitry to receive input signals from the display/control panel and fluid circulating system and to generate system control signals to control the operation of the fluid circulating system and system indicator signals to provide the visual indication of system operations.
