The 116 xx and 116
systems which are designed to perform thermal disinfection for prevention of Legionella. When the
disinfection cartridge senses 160°F (70°C) -116
temperature options), indicating disinfection control mode, it automatically opens a by-pass flow
path to allow sufficient flow for disinfection to occur. When the temperature drops back to normal
range, the disinfection by-pass cartridge closes to return flow control to the balancing cartridge.

The 116 xx Series is also available with a "disinfection" valve that is controlled by a 24V spring
return normally-closed thermo-electric actuator, rather than thermostatically, thus allowing
thermal disinfection mode to be controlled remotely by an automation system.
The valve is ICC-ES certified to NSF/ANSI 61 (180°F/82°C Commercial Hot) and NSF/ANSI 372, low
lead laws. It meets codes IPC, IRC, UPC and NPC for use in accordance with the US and Canadian
plumbing codes.

Function
The ThermoSetter™ adjustable thermal balancing valve is used
for automatic balancing of recirculation loops in domestic hot
water systems, to speed hot water delivery, reduce water waste
and save energy. The internal thermostatic balancing cartridge
automatically modulates flow to ensure a constant temperature
in the recirculation piping system. The 116 Series has an
adjustment knob with 95°F to 140°F (35°C to 60°C) temperature
scale indication. An integral dry-well holds a slide-in temperature
gauge for local indication, or a sensor for remote temperature
sensing. The optional check valve protects against circuit thermo-
syphoning.
