Program help...

[WarDaddy]

I have a fans on the sump to help cool when it is warm.

The fan program is as follows:

If Temp > 80.0 then COL ON
If Temp < 79.5 then COL OFF

It works fine... BUT I get an undefined icon when the temp is between 79.5 and 80.0. Is that a problem?

That's ok. If your temperature happens to be in between those values (like 79.8 for example) when you return from editing or changing a setting in the controller, the display won't know the last state of the device so it displays a U. Nothing to worry about.
