how to reset temperature controller

Some users may mistakenly modify parameters, which may cause equipment abnormalities. It is recommended that users who are not familiar with the Settings use the factory reset function

When using temperature control devices, everyone is bound to encounter problems such as abnormal device functions, temperature control failures, or operational malfunctions. When the problem cannot be found after basic troubleshooting, the choice will be to reset the temperature controller - to restore the factory default logic

If you find it troublesome to adjust the parameters and only follow the step-by-step process in the manual, and if you are not good at adjusting the middle part, it will be very chaotic, then restoring the factory Settings is your best solution.

Before resetting, record all the current parameters because this is beneficial for you to make a comparison after the reset and helps you distinguish the correctness

While troubleshooting the thermostat, the first step we should take is to start with the power supply failure. We must ensure that the power is turned on and the connection is correct to confirm its safety. 

If the connection is incorrect, the sensor may cause incorrect temperature readings due to the fault. There are also some details to pay attention to. Check if there are any signs of detachment in the terminal wires for wiring. Poor contact can also have an impact. Rusty terminals, high scratches, leakage, short circuits and other situations all need to be checked first to ensure that                                                                                                                      the current circuit does not have problems. So let's take a look at how to reset the temperature controller specifically? 

Press the S key and the left mouse button simultaneously for 3 seconds. The upper PV screen will display P-4. At this time, enter the password 0911 and then click the S key.

At this point, the PV screen of the instrument will display a value, that is, confirm the selection before restoration.

At this point, PV and sv will be set to the same value by default. Then, click the Up key to change it to the normal value

Then click the S key again. Now the factory Settings have been restored and you have returned to the working mode interface

At this point, our reset of the thermostat has been completed

One point to note: Before resetting the thermostat, please write down the circuit information so that you can easily input the controller's circuit when needed.
