Discuss the outdoor reset control.
What will be an ideal response?
The outdoor reset control is the device that senses the outside ambient temperature and adjusts the boiler water temperature accordingly. In theory, as the outside ambient temperature increases, the occupied space will require less heating, so cooler water can be used. Conversely, when the outside ambient temperature drops, hotter water will be needed to heat the space. When cooler water can be used, energy is saved.
