What does that mean? I don’t understand
You should be able to find it by checking the error code in the manual for this digital display
Digital temperature display? Check the internal configuration parameters or wiring methods; some digital displays output signals differently, and the short-circuit wiring methods on the circuit board also vary

For these digital displays, for a given series, the manufacturer usually provides just one set of instructions to cover everything. If what you have isn’t in those instructions, you can search on Baidu for the instructions related to that same series, and by using the instructions for the highest-model version specified by the manufacturer, you’ll be able to find the necessary explanations. I really can’t find the manufacturer’s phone number. There’s also what a user upstairs mentioned: by setting jumpers on the circuit board and inserting or removing the jumper caps, the setup interface that is accessed will change as well. We have a 731 digital display here; during normal operation, the jumper cap is removed. When setting it up, power is turned off, the jumper cap is inserted, and upon powering on, the setup interface is accessed. This is my personal opinion for reference only.
