Weather Responsive Controls


Weather Responsive Controls

The easiest and most cost-effective way to reduce fuel is to use a weather-responsive control, also known as an outdoor reset control.  To learn more about how they work and the benefits they can provide, please read the article in our Noteworthy section of this website.

Buderus Logamatic

Simple operation, intelligent functions: that is the basic concept of the Logamatic 2000 Series. Buderus Logamatic controls monitor both indoor and outdoor temperature and accordingly adjusts boiler temperature to actual demand. Lower operating water temperature decreases cool-down and flue gas losses which translate into lower energy consumption and fuel bills.

  • Reduces annual fuel consumption by up to 30%
  • Delivers unsurpassed comfort
  • Suitable for residential and commercial applications
  • Unsurpassed heating comfort with increased efficiency
  • Quieter heating system operation with outdoor reset
  • Simple operation through “push and turn” dial concept and digital display

Taco PC700

The Taco Boiler Reset Control is 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.
