1.Press and hold the power button to enter the temperature control startup state.
2. Press and hold the S button to display the setup code, such as HC, D, LS… AL et al.

Code HC – Heating/Cooling  H/C
Code D: Deviation
Code LS – Lower limit setting
Setting of the upper limit for code HS
Code CA – Temperature Correction
Code PT: Delayed Startup
Code AH: High Temperature Alarm
Code AL – Low Temperature Alarm

Example of settings: Heating mode
Set stop temperature – Minimum temperature = Offset
For example, if you want to heat a certain device to 25 degrees and stop when the temperature drops to
20 degrees, and then restart heating how should it be set?
Setting method:
Set the mode to H
Set the temperature to 25 degrees and the offset to 5. Then when
the temperature is higher or equal to 25 degrees, the relay will open and the output will be turned off.
When the temperature is lower than 20 degrees, the relay will be reconnected and the output will be activated.

Example of settings: Cooling mode
Set the start temperature – minimum temperature = deviation
For example, if you want to control a certain device to stop at 23 degrees and start cooling again at 27 degrees, how should it be set?
Setting method
Set the mode to C,
Set the temperature to 27 degrees, and the deviation to 4. Then when
the measured temperature is lower than 23 degrees, the relay will open and the output will be turned off.
When the temperature is higher than or equal to 27 degrees, the relay will be re-activated and the output will be started.
