My Ranco temp controller is acting weird. I just plugged it in for the first time in several months. It showed the current temp in my cellar (59F) and when I scrolled through the settings it showed the most recently used settings - cooling mode, temp differential of one degree, and set point of 2 degrees. All seemed right, as the last time I used it, I had set the temp low to maintain my freezer's temp at a certain point. Now that I want to use my freezer for a beer cooler again, I wanted to change the set point to 33. No dice. It won't let me set the temp higher than 30. Any idea what is going on?
Apparently I was being stoopid. It was set to degrees C, and wouldn't let me drive the temp higher than 30 degrees. I thought I checked this but maybe double tapped the key pad when I thought I single tapped? Once I switched to degrees F, 30 degrees takes on a whole new meaning. At 30 C, my freezer was never going to shut off. A dry eis-stout would not be my favorite. Edit: Nutz. I decided I better double check rather than assume that I really did solve the problem. The above solution is incorrect. My cooler was at 56 F, not the 35 F set point. The real stoopid move was that it I had the differential maxed out at 30 degrees. Beer and cold medicine just doesn't mix, boys and girls.
Thanks for the update. I know it's easy to say after the fact, but I was going to ask if by chance you changed it to Celsius. I hesitated though because I also thought the controller could be set higher than 30 degrees Celsius. My "home brewery" is actually at my buddies house and I wasn't able to get there yesterday to look at my ranco's and test my theory / see if I was remembering correctly. Glad you got it working again!
