Performance Requirements for Automatic Temperature Control Mixing Valves

ANSI Approved: February 2020

ASSE 1069 devices are intended to control the water temperature to individual or multiple fixtures to reduce the risk of scalding and thermal shock. They are intended to be installed where the bather has no access to the temperature adjustment means and where no further mixing occurs downstream of the device. This standard was developed for devices that service end use fixture fittings including, but not limited to, gang showers and sitz baths, by supplying tempered water at a preset temperature through a single supply pipe
