Has anyone had issues with there Ranco controller not reading the correct temp.?
I will have to verify my temp. with a glass floating thermometer, but i'm thinking my Ranco has been giving me a reading quite a bit higher than actual temperature.
My 'little time & temp'' thermometer is reading 72.5 while my Ranco reads 78. I had the LT&T running in a smaller tank and it was giving me a reading of 78.5 and the water felt much warmer than the tank(s) with the Ranco controlling them. The Ranco has a set point of 78 degrees, 77 and the heaters come on, 79 and the fans come on.
I then took a small cup of water and put 3 ice cubes in there and put the LT&T probe in and let it sit till the temp. settled down and it did so at 33 degrees. I put the Ranco probe in the same glass of water and it settled out at 39 degrees. :confused:
I've never had weird reading on the Ranco which would lead me to belive the probe is bad, but I suppose that's a possibility. The unit is probably about 1.5 years old.
