Try this:
First, make sure that the keypad is not locked by pressing the up and down arrow simultaneously for about five seconds. If the keypad was unlocked, it will lock it. If that doesn't work, unlock the keypad and try turning off the power for 5 minutes and then back on.
If that doesn't work, try this:
Turn off power to the pump.
Open compartment where power wires connect.
Note wire color order at the red 4 wire connector.. It should be 1)Red 2)Black 3)Yellow 4)Green.
Disconnect the two center wires (black and yellow) of the four wire set connecting the JEP-R to the pump.
Don't let the ends touch anything or each other.
Turn on power and load defaults.
Turn off power.
Reconnect the two center wires.
Turn on power.
Reprogram settings.
The power center supplies the controller 10 VDC via the two (2) outside wires (red and green) of the four (4) conductor cables. The two (2) inner wires (yellow and black) provide the two-way communication link between the controller and the power center.
By disconnecting the center wires, you should be able to regain the ability to load defaults.
Check for 10 volts DC to the red and green wires if the above process does not work.
If you have 10 volts dc to the controller and the above procedure did not work, you probably need a new JEP-R.
Below is the procedure to load defaults, which resets settings to factory settings.
