Outdoor temperature reset controls is an energy-saving heating concept, tested and approved by numerous government agencies as the most effective system to save energy.
Users of outdoor reset controls, coupled with particular boilers, qualify for some tax rebates and incentives.
If your building is heated by the use of an overheated water boiler. In that case, the boiler will maintain a specified water temperature all year round, usually between 160°F in addition to 200°F, the outside weather conditions notwithstanding, this will result in occupants feeling much warmer while we were in fall and springtime! However, your area temperature will be less sizzling while we were in the cold winter time months due to the faster energy escape while we were in extremely low temperatures. Outdoor reset controls respond to weather swings by decreasing the temperature of the boiler water circulating throughout your building. It sends cooler water out to your heating and A/C system while in warmer outdoor temperatures and sends warmer water to your building while in cooler outdoor temperatures. The outdoor reset controls then control the amount of energy getting into your building based on your outdoor temperature by adjusting the boiler water temperature. This provides an almost perfect equilibrium where the energy getting into your building is equivalent to the energy getting out. As a result, you will maintain a steady indoor temperature throughout the year and save significant energy costs. For every 4°F, your boiler water temperature is lowered, there is a 1% energy savings. The reset ratio is a regulation that allows you to accomplish the equilibrium between your heat input and your heat loss for optimum energy saving.
