Abstract
A differential temperature display system for balancing hydronic systems includes a first sensor for sensing a supply temperature and for outputting a first signal indicating the supply temperature. A second sensor is adapted for sensing a return temperature and for outputting a second signal indicating the return temperature. At least one integrated circuit is adapted for calculating a differential between the supply and return temperature. A single electronic display is adapted for displaying one of the supply temperature and the differential. A method of using the system is also disclosed.
