Controller settings

<span style="color: black;"><span style="font-family: Verdana;">I'm setting up my controller and started wondering what some of the advanced features others run on their system. </span></span>
<span style="color: black;"><span style="font-family: Verdana;"> </span></span>
<span style="color: black;"><span style="font-family: Verdana;">List actual temp ran by unit (Chiller, Heater) and then the settings used on your controller. Last and probably more important for me, what are the additional redundancies you run e.g. turn MH on when tank temp falls below ___.</span></span>

High switch ATO emergency shut off

I run my lights, UV, Skimmer Pump etc...as controllers using heat as the setpoint - above 82 they start to shut down and fans kick on.

Failsafes to turn off alk doser of PH goes too high. PH too low, doser kicks on.

When return pump is off, UV automatically shuts off.

Temp below 78 and chiller gets turned off completely

Temp below 78 turns on 2 heaters set .5 degree apart, lights come on in case both heaters fail (my lights produce some good heat).

I monitor Salinity but havent tied any controls to it yet such as kicking on ATO if salinity gets too high

I am not sure I would use the light as a backup heater.
I had my return pump stall and the probe fell dry (in my overflow box) - so it registered ambient air and kicked on all heaters.
If it had kicked on my lights (due to the low water) it woulda literally fried my corals...

My probes are in my fuge and the return pump is sectioned off so in event of pump failure it wont let the probes go dry. I see your point though.
