When the ECB-001 controller is turned on, the P.I.D. will be the OPERATING mode by default.
To change the temperature scale from Fahrenheit (F) to Celsius (C), press and hold down the ENTER key for 3-4 seconds to get into the INITIAL SETTINGS mode.
Then use the INDEX key to scroll through the different initial settings until you find the “tPUn” parameter in red, which should either be displaying an “F” in green.
Then, use the UP arrow key to change the F to a C.
Then, press the ENTER key to lock-in that setting.
Then, press the ENTER key again to get out of the INITIAL SETTINGS mode, and back into the OPERATING mode. The temperature scale should now be in Celsius (C) instead of Fahrenheit (F) as evident by the yellow indicator light next to the letter.
While in the OPERATING MODE, the temperature (SET VALUE) can be adjusted by using the UP and DOWN arrow keys, followed by pressing the ENTER button to lock in that setting.
