The first number is the gap between the box and the setpoint
Umbel writes the box temperature and the setpoint before a shop is told the unit failed.
I start a reefer call with two numbers. The driver reads the box, which is the air coming back from the trailer, and then reads the setpoint the unit was told to hold. The ticket is the difference between those numbers. A box at 48°F against a 34°F setpoint is a 14°F gap. That gap is what the shop hears.
Dispatchers who accept “it’s not cooling” send the wrong truck. A unit sitting on the wrong setpoint will look failed and still be healthy. A unit that has lost its compressor will show the same complaint and a gap that will not close. I keep both numbers on their own lines so the shop can tell those calls apart before they leave the bay.
If the driver can only see one display, I ask which number it is. Some panels show setpoint until a button is pressed for return air. I write “box unknown” when the driver cannot separate them. I do not invent a temperature to make the ticket look complete.
The shop confirms the numbers on site. My figure is the intake. Their gauges decide the repair. Crew-days for the visit are estimated later, from the hours the repair needs, and a loaded trailer that cannot be opened sits outside that figure.
The note "The first number is the gap between the box and the setpoint" starts from the line already on the ticket. I start a reefer call with two numbers. The driver reads the box, which is the air coming back from the trailer, and then reads the setpoint the unit was told to hold. The ticket is the difference between those numbers. A box at 48°F against a 34°F setpoint is a 14°F gap. That gap is what the shop hears. A reefer call starts with the temperature on the box and the setpoint, not with the word broken. Umbel records both, plus whether the load is still inside, then holds one shop. Umbel reads that back before a time is offered.
What the company sees for "The first number is the gap between the box and the setpoint" is the next line of this note. Dispatchers who accept “it’s not cooling” send the wrong truck. A unit sitting on the wrong setpoint will look failed and still be healthy. A unit that has lost its compressor will show the same complaint and a gap that will not close. I keep both numbers on their own lines so the shop can tell those calls apart before they leave the bay. Reefer crew-days at /reefer-trailer-service-hours is a planning figure. It is not a bill, and it is not a promise the visit is already staffed.
"The first number is the gap between the box and the setpoint" does not send ReeferTrailerAndColdChainEmergencyDispatch out to do the work. If the driver can only see one display, I ask which number it is. Some panels show setpoint until a button is pressed for return air. I write “box unknown” when the driver cannot separate them. I do not invent a temperature to make the ticket look complete. One paid company gets the request. The street address stays off the offer until that company claims it.

A reefer call starts with the temperature on the box and the setpoint, not with the word broken. Umbel records both, plus whether the load is still inside, then holds one shop. Passing the request is allowed. A group text is not the dispatch. The record stays on the job the company opens in the morning.
A caller asking about "The first number is the gap between the box and the setpoint" still has to leave the facts Umbel asks for on the first ring. A reefer call starts with the temperature on the box and the setpoint, not with the word broken. Umbel records both, plus whether the load is still inside, then holds one shop. If the office is closed, those facts have to be on the ticket before the morning crew starts. The company that claims the request confirms the window.
The planning figure behind "The first number is the gap between the box and the setpoint" is there so the board matches what the caller heard. Reefer crew-days does not price a finished job and does not certify the work. ReeferTrailerAndColdChainEmergencyDispatch is dispatch software. A local company fulfills the visit, and the timing depends on that company's capacity.
