I have 3 of these, 2 in one tank and one in another.
1 of them stopped working (the 2 in the one tank) a few days ago, the other just a few hours ago.
They all flash/blink the top 2 dials and the orange light for the external control setting.
I know this cannot be defectives as the odds of all 3 being bad would be slim.
Any advice on how to get them working?
