NADA 2-Tank SVO System Controller

Product Description
Includes our MFT Timer Relay to stagger the purge when using two 3-port valves, as well as the Vegsensor to control the Vegtherm inline electric heater, a toggle switch (to control both supply and return valves, since you are using the MFT), and our "Forgot-to-Purge buzzer". Great value!
