How to set a Ranco controller

[moondoggy4]

Hello, I have noticed that my tank is running a little cold and I am wondering how do I change my Ranco controller to a higher set point? Thanks in advance

Just increase the temp on the controller. Not sure if this is what you’re asking, or having a problem with? If the heater still isn’t going on, decrease the temp on the heater below where you actually want it, so it will go on when the controller switches it on. I believe that’s how it works.

Thanks, I have a titanium Finnex heater without a built-in thermometer. So I will try that.

I think your tank is too big for just one heater.

Thanks, everyone, this is for my 120-gallon tank.
