New to the reefer madness

I thought you were talking about this.

 

Should be a dedicated button on the panel marked "continuous/cycle". Push it once to toggle back and forth between continuous and cycle. It will indicate on the screen what mode it is in.

 

What @STexan said is your answer.

 

Based on what you posted earlier about your unit starting and stopping (cycle), then it appears your unit is programmed to limit available modes, based on the set-point temp selected. For instance on our frozen loads in our fleet, we can ONLY run cycle on deep freeze loads. Continuous is only an available option above a certain set-point.

 

I guess this answers why we are trying to make trucks drive themselves. We can't even trust a driver to put the unit to a set point then push the button which has 2 circles side by side on it to select proper way to run the unit for the particular load.

I have found it better to leave on continuous for the frozen loads. Seems to burn less fuel and the engine doesn't have to run high idle for a half hour only to shut off for 5 minutes. Also seems to almost never have to defrost. Just my experience.
