We have 2 fridges and one freezer on board. We’re on the boat for an extended time and I had fun calibrating the settings with remote thermometers. What struck me was the impact of the stove and also how the fridge warmed after putting warm items. All expected, but fun to see it quantified. One sensor in the freezer, one in the fridge. Works great. Adjusted the freezer to 10 degrees F, and the cabin fridge to 35 F. Took about ½ day to get it stabilized. Using the electric stovetop above the fridge and freezer for ½ hour raised the fridge and freezer 14 degrees and 9 degrees, respectively. Next, put a sensor in the cockpit fridge and got it stabilized to 38. Putting three 73 degree 16 oz glass bottles in it raised the temperature to 42, and it took about 45 minutes to get back to normal.
