CircuitSolver® with Thermometer Assembly

The thermometer assembly can be purchased independently or integrated into any CircuitSolver® automatic balancing valve configuration for effortless installation. Every integrated design is fully assembled and tested for accuracy and leak points before leaving our facility.

How It Works:CS Group with thermometers 300x194 - CircuitSolver® Thermometer Assembly

Installed at the end of each supply branch, the automatic CircuitSolver® balances the domestic hot water system by continuously adjusting flow through each balancing valve to maintain a set temperature at the end of each supply branch and keep hot water at fixtures.

The CircuitSolver® thermometer assembly monitors in-line water temperatures with an easy-to-read dial for instant hot water temperature verification.

Typical Applications:

The thermometer assembly can be used in addition to any new or existing CircuitSolvers® balancing valve installations. Used in commercial buildings of all sizes and in domestic hot water recirculation systems with varying complexity, CircuitSolver® installations often include hospitals, schools, hotels, high-rise buildings, and multi-family apartment buildings.
