HYDRONIC COMPONENTS & SYSTEMS
Variable Speed Outdoor Reset “00” Circulator (00-VR) Application
Outdoor reset controls the hot water supply temperature,so that the heat supplied to the
building equals the heat loss by the building. The 00-VR modulates the circulator to inject
hot water from the boiler loop into the radiant or reduced temperature loop while providing
Outdoor Reset to a heating system (see figure A). Available in any style 003 – 0014,the 00-VR
also comes with a boiler sensor to protect against low return temperatures. The 00-VR is
the ultimate for protection,control,ease of installation,and trouble free operation.
Variable Speed Setpoint “00” Circulator (00-VS) Application
The versatile Setpoint version of the Variable Speed “00” can be set up to deliver a fixed
temperature,maintain a specific temperature drop between sensor locations (∆T),used as a
bypass / shunt pump or integrated into a fan coil package to vary the speed of the pump based
on supply air temperature.
The 00-VS can be either direct acting (speed increases on a temperature decrease) or reverse
acting (speed increases on a temperature increase). A typical direct acting (limiting setpoint)
application would be for boiler protection,where the 00-VS is installed on a bypass loop (see
figure B). If the return temperature starts to drop below the set temperature (75°- 165°F) then
the speed of the pump will be increased,bypassing hot water to protect the boiler.
The 00-VS can be used in radiant injection mixing systems where you want to set a fixed supply
water temperature (see figure C). Through the use of the setpoint dial on the PC board any
temperature from 30°-210°F can be selected. If desired,a boiler protection sensor can be
installed to protect the boiler from flue gas condensation.
In the ∆T mode the pump speed is varied to maintain a set temperature drop (5°-50°F) across a
boiler or heat exchanger,ideal for snowmelt applications.
Variable Speed Variable Voltage “00” Circulator (00-VV) Application
The Variable Voltage version of the Variable Speed “00” Circulator is designed to operate the
pump at different speeds based on an externally generated analog voltage signal input. Its reli-
able operation,ease of installation and integration to DDC or building management systems
allows for a wide variety of HVAC applications,such as maintaining a pressure differential or a
setpoint temperature.The control accepts a 0-10 V(dc),0-20 mA,2-10 V(dc),or 4-20mA signal.
