Posted: Sun Feb 04, 2018 7:28 pm
Hello I have 5gal of water in my fermenter that I am testing with my new dual ranco temperature controller. The reason I am testing it is one my use refrigerator an 2 to get to know my new brewing equipment. Well I have the controller in a Thermowell am hook up to the refrigerator but here the confusing part I have my controller set to 70f with a 1f differential but the temperature readout on the controller itself say it’s at 67f should I use a heat source to get it to the 70f were my controller is set at an also the refrigerator is in my apartment.
