Description
–
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.

EXCELLENT PRODUCT. GREAT BUY.
Great product. My heating specialist was able to install and program the unit within an hour. Original unit got hit by lightning. Very satisfied so far. Not "cheap" but worth it when you don't have any heat !!!!

Taco PC705
Using the PC705 with a SR504-EXT in a deep slab for radaint heat works well at maintaining water temp. Adjusting water temp with outside temperature change is what you need to keep room temperatures.
