How exactly do you control your temp and what number do you center on?

The main reason for my chiller is my husband hates the sound of any fan. So, I have a chiller in the basement with the rest of the life support and the tank is upstairs in the main room. He is happy, tank is happy. Sometimes it it worth the extra money.
If the chiller were in the same room with the tank it would never go over for noise issues.

Two Ranco controllers one set to 78° F with a 1° differential the secondary is set to 78° F with a 2° F differential. I have a mix of Ehiem and BRS heaters.

2 eheim heaters set to whatever point I want (77 currently). Inkbird as a failsafe. Inkbird shows always heating (ie supplying power to heaters).

This is exactly what I do in my 40 gallon -- my rationale was:
-- Eheims will likely fail one at a time so no damage done and cheap/easy to replace each as it fails.
-- InkBird SHOULD last longer since it's not ever switching on/off (((at least unless/until a heater gets stuck on)))
