Question
I have 9 stations active, but only the 1st 6 now show up on the LED display. When I slide the station switch to the 7-12 station position stations 7,8 & 9 will not display on the station 1, 2 & 3 slots as before as though I have only 6 stations that are active.

Answer
Hi Lowry

Probably the slide SW is no reaching the micro SW on the board. You can bring the faceplate to service.

Run a raster test to make sure the stations circuit is good. Set the controller to off, press at the same time the on and off buttons, the display will look scrambled, press adv. Station 1 to 9 should says pass, stations 10 to 12 should says open, mv should says open, unless you have a pump.

If the messages are as expected, and the problem persists, turn off, take out the battery, and disconnect the power to the controller, wait a couple of minutes, install the battery, turn on the power and check it.

Let me know if you need further help,
