Designed to improve performance in your hot water heating systems by regulating the supply water temperature of a single boiler based on the outdoor temperature. The control utilizes a heating curve to set the relationship between outdoor temperature and supply water temperature to provide optimum control and comfort. Thanks to its integral microprocessor, the PC700 is able to continuously adjust the boiler differential to avoid boiler short-cycling and large temperature swings, Standard functions include warm weather shut down, minimum boiler supply temperature setting, and a starting water temperature setting. A liquid crystal display clearly shows the boiler supply temperature and other monitored temperatures and settings for simple and effective control.

The PC700-2 is a microprocessor-based control designed to regulate the supply water temperature of a single boiler, based on the outdoor temperature. A wiring harness is provided to be easily connected to the Taco Expandable (-EXP) Controls.

The PC700-2 includes functions such as automatic reset ratio calculation, Warm Weather Shut Down (WWSD), Minimum Boiler setting, and an optional automatic boiler differential. The control has a digital, liquid crystal display (LCD) that normally displays the boiler supply temperature, but can display other temperatures and settings.
