With the Taco Variable Speed Pump Mixing Control you can regulate the supply water temperature to a heating system by simultaneously controlling a boiler and the speed of an injection pump. Based on the outdoor air temperature, the PC705 continuously adjusts the boiler differential to optimize the firing cycles of the boiler, prevent large water temperature swings and increase the efficiency of your system. As the heating load changes, the Taco Mixing Control automatically adjusts the injector circulator, increasing its speed as load increases and slowing it with a decreasing load.
The Taco Mixing Control features full diagnostics, including a lighted bar graph that simulates the speed of the variable speed injection pump, warm weather shut down, a maximum supply water temperature setting, and a sensor that can be connected to the boiler to prevent corrosion in the unit due to flue gas condensation.
Putting added control onto your systems has never been easier. Just use Taco’s PC700 series of Power Controls along with any Taco Expandable Relay Unit (-EXP model). There are no complex wiring diagrams. Simply plug the interface cable directly into the expandable relay and attach the supplied sensors. That''s it. By controlling the supply water temperature based on the outdoor temperature, the heat lost from the building is matched by the heat input to the building. You also optimize firing cycles of the boiler to increase comfort and provide energy savings. With the PC700 Power Control’s ease of installation and full diagnostic capabilities, you can simply and easily upgrade any system. In addition, you can use Taco Power Controls in parallel with the PC600 Series PowerPort Cards to further enhance total system operation.
