Heater and apex help

[Crabby48]

I’m new and little confused what would work best for me. I have 110 gallon total water volume with two 200 watt eheim jager heaters.
I’m not shore if I should use apex to control heaters and heaters as backup or use the apex as backup?
What are the pro’s and cons?
Also what should I set the temp on the heaters vs apex.
Should I set the temps on the heaters the same or a degree off.
My house in the winter stays 62-65 degree

I use apex as the primary control and the integrated thermostat as back up. Just set the latter to turn of a few degrees above the former. You can set the two heaters to different set points if you want, though I never really saw much point in it.

How is something like this
set apex on at 77, off at 78 and the heaters set to 79

Conceptually fine, though you may have to play around a bit with the stick heaters. The integrated thermostats are notoriously inaccurate.
