TempAssure® Thermostatic valves monitor the temperature of the water and adjust the mix automatically to maintain precise temperature control and to keep the water temperature in your shower within a safe ±3° F (±1.6° C). This provides a more consistent temperature than pressure balanced valves can supply.
TempAssure valves also feature an adjustable high-temperature limit stop that when properly set helps ensure the handle cannot be turned to a position that is too hot for comfort. And because TempAssure measures the temperature of water, the handle limit stop will not need to be adjusted for seasonal ground water temperature changes.
Note: To protect sensitive skin from water that is too hot, select a faucet that lets you set the maximum water temperature and remember to limit the maximum temperature at your hot water heater.
