The 116
xx Series is available with a "disinfection" by-pass cartridge, for use in systems which
are designed to perform thermal disinfection for prevention of Legionella. When the disinfection
cartridge senses 160°F (70°C) water, 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.

The outlet never fully closes to always allow a minimum flow for temperature sensing and to prevent recirculation pump dead-heading.

Page 6: Installation Tip
Function C - Actuator-controlled disinfection The 116 xx series operating characteristic curves for operating mode C are curves 1, 2 and 5. When the disinfection operating temperature setting of the electronic disinfection system is reached, the thermo-electric actuator 656 series (which is controlled by a dedicated electronic control system), is energized to operate the by-pass valve to control the disinfection process, allowing flow independent of the operation of the thermostatic balancing cartridge shown in curve 5. - Page 7 Code Mass (kg) 116240 1/2" 18,5 74,5 0,750 Dimensions 116250 18,5 74,5 0,700 B’ Code Wt (lb/kg) 116140A(C) ½" NPT F " ¾" 3" 1.7 / 0.75 " 116141A(C)** ½" NPT F " ¾" 3" 1.7 / 0.75 " Code Mass (kg) 116150A(C) ¾"...

Page 8: Flow Characteristics
Flow characteristics The ThermoSetter thermostatic balancing valve is designed to balance individual branches of domestic hot water recirculation systems, based on the temperature at the valve. It automatically modulates flow to maintain hot water availability to all fixtures in the branch circuit. The valve is at minimum flow (Cv = .23) when the incoming water temperature is equal to the set-point position of the adjustment dial. - Page 9 Temperature adjustment Set the desired recirculation system temperature by turning the adjustment knob. The graduated scale shows the temperatures at which the indicator can be set. A valve temperature setting at about 10°F (5°C) higher than the water temperature at the valve inlet is recommended, accounting for heat losses along the line, to limit the head required at the recirculation pump.

Page 10: Maintenance
Maintenance Both the balancing adjustment cartridge and the disinfection control cartridge can be removed from the valve body for periodic inspection, cleaning or replacement. Innsulation shell The ThermoSetter thermal balancing valve can be supplied with an optional insulation shell, code CBN116140 purchased separately, to minimize heat loss. - Page 11 Application diagram Hot water recirculation with thermal balancing valves 140°F 130°F 130°F 130°F NOTE: Do not set at temperatures >120ºF if anti-scald valves are not installed at the fixtures. 120°F Hot water recirculation with actuator controlled disinfection THERMAL DISINFECTION 230 V 50 Hz CONTROL UNIT/ B.A.S.
