Function
The ThermoSetter™ 1164 series 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 105°F to 150°F (40°C to 65°C)
temperature scale indication. The adjustment knob is lockable for
tamper-proofing. 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.
