Heater recommendations ... again (and Hydros questions)

[richiev]

I have been doing C for 3+years now. I don’t understand the problem. When I lose WiFi, hydros continue to function . You only loses the ability upload new programming . Existing programming will continue to run.

I’m using XP8 . Maybe the WiFi strip has different behavior.

The XP8 is the missing link (dangalang clarified that above). When I was researching I only saw the wifi outlet which is why I was so confused.

I don't actually have a controller on the tank, not sure I'm even going to add one, so I don't really have a history of what the temp ranges are currently. But every time I look, tank has always been between 77-78 degrees.

I have usually used the Ranco thermostat, to control heat, but there is a relay in there so it can potentially wear out eventually. I'm actually thinking of switch to have Ranco just shut off the heater if it goes to 80F and use the heaters thermostat to control day-to-day since that is less expensive to replace. And in cases that there's an aquarium controller, I'll have that shutoff at 81 degrees.

Just got a second unit today for the backup heater. And interestingly enough, they both read the same temp. Usually doesn't happen and two units are off by a little bit. But to answer your original question, it looks like it only heats it when it goes off by a whole degree. It's at 77.1 and it hasn't turned on yet (Heat is set to 78). That's good enough for me though, I don't need the temp to operate in such a tight window.

Edit: temp just dropped by 0.1 and heater turned on.
