Application
The thermostatic mixer is used in systems producing domestic
hot water or in radiant panels heating systems. Its function is to
maintain the temperature of the mixed water supplied to the
user constant at the set value when there are variations in the
supply conditions of the incoming hot and cold water. The valve
has been specically certied to ASSE 1017.

Typical Specification
Furnish and install on the plans described herein, a Caleffi
Three-Way Thermostatic Mixing Valve as manufactured by
Caleffi. Each mixing valve must be designed with a brass
body, a replaceable brass cartridge chemical nickel plated,
stainless steel springs and seals in EPDM. Each valve must
also be designed for ±3°F (±2°C) temperature stability with a
tamper proof control knob to lock the temperature at the set
value. The valve shall be ASSE 1017 approved for point of
distribution installation. Each valve shall be Caleffi model
521 of approved equal. (See product instructions for specific
installation information.)
