Temp probe placement

[unclephatpat42]

Okay so where should I place my temp probe for my specific sump?
It's a eshopps r300

Some info.
Return pump space is a small area, just barely fits my vectra L1 so I figure it's just gonna be a bit warmer there.

Sump and heater in the compartment to the right, labeled.

Middle compartment is a refuge, really slow flow through there.

Return pump and skimmer are the only equipment generating heat in the sump.

Thank you for your help.

I'd put it on the side where water comes into the sump

I had tried to put it in the return area but lately moved it into the tank next to the overflow box because I discovered one night that my return section in the sump is almost 3 degree lower than my tank. Luckily I have a backup thermometer setup in my tank and saw the temperature climbing close to 80 while I set my tank at 77.5.

Sump is common place, away from any pumps and to strong flow.
I have mine setup in the overflow baffle that puts water to the return pump.

I have mind in the overflow section (weir) of my DT Yes or No?

Down stream of the heater. Never above. That allows the heater to come on and off more often giving a more steady heat. If you put your probe above stream it might have a bigger temp flux. Say your fuge is 86 but display is 78. Down stream. It can be in daffles down from the heater.

Not a good place, you want that place free of any objects, best place is the sump away from any heaters. Or in the display back glass away from anything that could hit it. Why the weird temperature setting? 77.5?

Depending on what brand your heater is most really dont work in .5 resolution. Very few actually can maintain a temperature that dead on target.

Most work in 2 degree to 1.5 degree swings, so they will let the tank dip down 2 to 1.5 degrees before bringing it up to its set point.

Then there are more industrial grade solutions with dedicated controllers that do cool things like PID.

I personally only use Eheim Jager units and cobalt Neotherm units. THe Jager units swing 2 degrees but are work horses that just don't quit. The Cobalt Neo Therms temp variation is well about as flat as it can get for a single set it and forget it solution.

BRSTV just did a video on heaters and that's what got me to switch to Neo therms, I set them up to control the temps and let my Apex be the safety mechanism.

cheers for that i am going to move it to my 1st section of my sump I.E were my drains enters.

don't know how large your probe is but I keep mine in the DT bc that's the most important area to heat/monitor. This way, if the sump is down for extended period of time for whatever reason, I can still monitor DT temp and put a heater in there if necessary.

Unless you have pathetic flow through the sump, it really doesn't matter. as long as it's at least 6 inches from the heaters. Put it wherever it is most convenient, and where it cannot be inadvertently pulled out of the water; otherwise all the arguments for one place over another are uncompelling.

I put my probe upstream of my heater, in the same compartment as the heater. This way I get a measurement of what the water temp is coming from my tank, not what radiant heat may be coming from the heater. And if my return pump were to fail, the heater cannot heat, the chamber it is in, to unsafe levels.
