    So I'm not very tech savvy and for my biocube the only thing I want to control is temperature. I've read that the rancos are very reliable and was looking at the etc-111000. Has anyone had experience with this controller? Also do I need to buy a temp probe or does it come with one?
    Thanks for the help!

    The Ranco is a very good controller. Wired it will cost you a little more than if you buy one that's not wired already. Doing it yourself is not hard just take a look at some videos on youtube. It does come with a temp probe, but it's not water proof, you'll have to make it water proof before putting it the tank. I have a Ranco and I have this one I bought from Amazon for the QT. It keeps the temp a steady 78 degrees, the only thing with this one is you can only set it in a 1 degree increment high or low, while If my memory is correct 30 with the Ranco.

    Ranco and Johnson Controls are almost identical and extremely reliable. I used a Ranco for my reef and a Johnson for my beer keezer kegerator for years.

    I have been using Ranco controller for my heater for abt 4 months (bought new from Ranco directly) model 111000. Today I saw that the display is showing 106 F but I know my water temp is only 79 F (I have a 2nd cheap digital thermometer) and all my corals and fish are normal. Any suggestions if there is reset button or the probe or the controller just went bad? I have also emailed Ranco

    Thanks

    Did you waterproof the probe? I've heard they can leak and give false readings if the probe is directly submerged.

    yep, I bought the probe already waterproofed by Ranco (the put on plastic sleeve around the probe and up so it's water tight

    after I left it air dry and unplug over night, I put the probe back into my water and the temp reading reduced to 81 (still about 3 degree higher than my tank's actual temp). I plan to leave it air dry longer. Is it possible there is leak in the plastic sleeve that caused misread? how do I fix this as the sleeve was made by Ranco directly

    Thanks

    I wouldn't think it was the sleeve, because on one of mine, it's pretty much in shreds.

    Thanks, that means I better send this back to Ranco. I will wait for their reply on Monday. It was working flawlessly for the past 4 months

    Ya, hopefully yours was just an oddball one. Mine have been so solid for all these years, I hate to think quality has dropped off at all, as they have for so many things.

    I had the same issue when I replaced the probe with a water proof one I bought off ebay. To fix it I had to add a resistor to the probe. I tested different resistors until I found the value that worked...I think it was either a 2k or 20k resistor.

    I trust the Ranco over my controller and built in heaters thermostat.

    I water proofed the temp probe by slathering silicone all over it.

    well, I sent in my Ranco to ETC supply (where I bought it), 1 month later, they said nothing wrong with the sensor or the controller and sent it back to me.
    I tested last night and the controller still showing high temp than the actual. My tank temp is about 79-80, and the Ranco showing 100 after leaving it overnight. I unplugged it this morning and plug it back, now showing 86. Again, it was working for 2 months or so. it has the pvc thermalwell installed by ETC supply to make it water proof. any suggestion?
    I already moved on to RKL controller but would like to sell this unit since it's practically new, but don't want to sell defective unit
    Thanks

    What is it you are using for the comparison temp? the RKL?
