The Problem The Solution Design Features
When entering water temperature is below the Circuit Solver™ setpoint, the thermal actuator will begin to open the valve to establish a fmow rate that will achieve the set point. If the water temperature exceeds the set point by 3°F , the valve will begin to throttle back to fjnd the current equilibrium point. Continuously operating at the
This constant, automatic response to water temperature enables each hot water branch to quickly and consistently deliver the right temperature of hot water to each connected fjxture.

Water fmows to the path
Many buildings require multiple branches off the hot water supply line. Hot water use is hyper-dynamic, so the path of least resistence constantly changes. Manual fmow control valves cannot effjciently resolve these issues.

Install a Circuit Solver™ on each hot water supply branch line immediately downstream of the last runout to a hot tap.

TMVEliminates the need to oversize system recirculating pumps to create constant fmow through manually adjusted balancing valves. Lowers GPM fmow in hot water return lines, minimizing erosion-corrosion problems caused by excessive velocity. Minimizes heat-loss by reducing fmuctuations in average temperature and GPM of the common return line.

The Circuit Solver™ will modulate fmow to precisely match system heat-loss. Install Circuit Solver™ in the hot water supply line as soon as it becomes a hot water return line (i.e., downstream of the last fjxture served by the hot water supply line). Note: Why use Circuit Solver™ when there are no branch lines?

COMMENTS AND CAUTIONS
Circuit Solver™ will evenly distribute hot water temperature to every fjxture as long as hot water is available. However, that cannot happen if...
There is a cross connection joining cold water to hot water. The recirculation pump is not working properly. There is signifjcant pressure differential between the cold and hot water distribution systems.
