00 Series Variable Speed Circulators

00 Series Variable Speed/Variable Voltage Circulator

The 00 Series Variable Speed/Variable Voltage Circulator is designed to operate the pump at different speeds based on an externally-generated analog voltage signal input. 00 Series Variable Speed/Variable Voltage Circulator’s reliable 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.

00 Series Variable Speed Solar Control Circulator

Taco 00 Series Variable Speed Solar Control Circulators combine the advanced features of our external speed and solar controls with the reliability and convenience of our 00® Cartridge Circulators. All the wiring for power and sensors is done directly to the circulator, while the LED status panel makes it easy to check functionality. The 00 Series Variable Speed Solar Control Circulators features dip switch based user configurable settings makes for a fast set-up, no matter the solar application. The 00 Series Variable Speed Solar Control Circulators continually adjusts its speed, maximizing the output of the collector, increasing the usable higher temperature water throughout the day, eliminating short cycling and increasing system performance by 20%.

00 Series Variable Speed Setpoint Circulator

The versatile 00 Series Variable Speed Setpoint Circulator can be set up to deliver a fixed temperature, maintain a specific temperature drop between sensor locations (DT), 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.

00 Series Variable Speed Outdoor Reset Circulator

The 00 ® Series Variable Speed Outdoor Reset Circulator controls the hot water supply temperature, so that the heat supplied to the building equals the heat loss of the building. It 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. Available in any style 006 – 0014, the 00 ® Series Variable Speed Outdoor Reset Circulator also comes with a boiler sensor to protect against low return temperatures. The 00 ® Series Variable Speed Outdoor Reset Circulator is the ultimate for protection, control, ease of installation, and trouble-free operation.

00 Series Variable Delta-T Circulator

Taco Variable Speed Delta-T Circulator’s all-in-one design combines a microprocessor based variable speed differential controller with the reliability and convenience of our 00® Cartridge Circulators. Simply dial in the design Delta-T of the system or zone (from 5 – 50°F) and then sit back and watch the circulator automatically adjust its performance to match the systems ideal BTU/hr output, while conserving energy and eliminating velocity noise.
