Differential Temperature Controllers

Goldline Differential Temperature Controllers are the brain of your SunMaxx Solar Hot Water System. By reading the temperature at multiple points throughout your Solar Hot Water System, the Controller is able to determine when your pump, and Solar Hot Water System, should be active and heating water, and when it should not. This simple Auto ON/OFF Controller can save you hundreds of dollars in electric costs by not using your AC or DC Pump when it is not needed.
