Product Overview

The ThermoSetter™ adjustable thermal balancing valve, 116 series
models, installed at the end of each branch of the domestic hot water
recirculation system, automatically maintains the set temperature. It
controls the water flow rate according to the inlet temperature with the
internal adjustable thermostatic cartridge. The thermostatic cartridge
modulates the valve opening in response to changing water temperature,
and when reaching the temperature setting, closes the valve to minimum
flow position. A recirculation pump distributes flow to all the branches
resulting in effective automatic thermal balancing. The automatic response
allows each hot water branch to deliver hot water to each fixture. The
ThermoSetter™ works perfectly with variable speed recirculation pumps
for optimal energy usage.
For systems using thermal disinfection for Legionella growth protection,
the 1162xx series models incorporate a second thermostatic by-pass
cartridge that activates at 160°F. A second flow path opens providing
flow for the disinfection process which is independent of the primary
balancing cartridge.
Alternately, the 1163xx series models incorporate a by-pass valve for
thermal disinfection which is activated by a optional field mounted
thermo-electric actuator, code 656 series, controlled by a automation
system.
