Aqua hot temp display has been working just fine.  During winter months, when stored, might go in and see it displaying word LO

but today, it is displaying "err"

Never seen that before.

Any ideas?????

Here is an earlier thread where I replaced the aquahot temp gauge with an Intellitronix.

I called the factory and they said it was probably a sensor. My aqua hot system, like yours, is working fine. Only the display it not working. I was told that there is a 3 wire system and a 1 wire system. If my memory serves me, the one wire system is newer. So when I take it over there, if I have the 1 wire; they'll just replace the sensor. If I have the 3 wire, then I think they'll have to replace both the sensor and display unit. Just haven't had time to take it over.
