How To Program a Jandy JEP-R Variable Speed Pump Controller
In this Article I go over the programming of the Jandy JEP-R Variable-Speed Pump Digital Controller for the Jandy Variable Speed pumps. The JEP-R looks complicated to program but is actually quite easy. The JEP-R overall is a good controller for your Jandy Variable speed (VS) pump. The JEP-R can hold two schedule speed programs and up to a total of eight different speeds. This is where it can be confusing. You can program only two speeds to come on at set times. For example you might want low speed to run from 7:00am to 1:00pm (eStar speed) and Speed 2 to run form 1:00pm to 3pm. So you can set these specific daily run times in the JEP-R in the first two buttons on the controller. Buttons 3 and 4 can be programmed for a specific speeds (the speeds on a VS pump are referred to as RPM). But they can only be set for a run duration time, like 2 hours, and button 3 and 4 will need to be manually started by pressing the button. There are also optional speeds 5-8 that can be s
