Hi Cosmo! Congrats on the conversion kit! Glad to hear from someone who did it. Now that you're with us, how about adding a first name and town to your signature line? We like to know each other, around here!
If you want to use the controller for time, make sure the second step of each program is set to "t," and not "F." This signals "time" as the trigger to change the program, not "temperature" (F for Fahrenheit). Once you program a couple of times, you'll get the hang of it! Just remember the 3 steps:
What box temp?
What trigger? (time or internal temp)
What time or temp?
That's the 3 elements of each of the 6 steps of the program.
