Controlling a Salt System or Booster Pump with the AUX Relay in a Jandy 2 Hp Vs Pump
The Jandy 2.0 HP Variable Speed Pump (VS pump) has a built in Auxiliary Relay which can be used to control a secondary device as long as it does not exceed 11 Amps. This is ideal for a Salt Water System or Booster Pump and this is a great way to control another piece of equipment through the VS pump. The Jandy VS pumps not connected to an automated system requires a separate controller and I prefer the Jandy iQPUMP01 interface over the older JEP-R controller. How the AUX Relay works is that you would wire the device power source according to the manual as a shared power source. A licensed electrician or licensed pool service technician should do this for you. Once the device is connected to the AUX Relay on the pump you can control that device by simply setting a higher RPM that will activate the AUX Relay. Any RPM above 1725 RPM will give power to the AUX Relay and activate the secondary device (Salt System or Booster Pump). So if you set your VS pump to run at 1400 R
