Many who use compressor type refrigerators will use an external temperature controller to increase the temp to 66f. This will reduce the amount of cycling and you will have fewer problems regulating Rh. Johnson Controllers makes a very good external controller. This combined with a couple of pounds of beads should be fine.
One thing to remember is that this time of year you probably wont even need to plug your unit into power. You have all winter to save up for the controller.
