TEMPERATURE
The RP2100 digital heaters will display metric (Centigrade) units. The factory default setting is Farenheit. If you open up the front panel so you are looking at the front of the digital board, you will find two small round buttons, labled S1 and S2. S1 is labeled "C of F". Hold down the S1 button for several seconds, until the board displays "CCC", this will set the board to display in Centigrade. Repeating the process will return the board to "FFF" which is Fahrenheit.
