Barber Colman Outdoor Reset Temperature Controls
This control provides a simple method of changing the controlled setpoint in relation to the outdoor temperature. One bulb senses the controlled media, the second bulb senses the outdoor air temperature. The temperature of the controlled media increases as the outdoor air temperature decreases, thus providing only the minimum heat necessary for the ambient conditions. this results in decreased heat loss and results in considerable energy savings.
