1. Lower limit deviation alarm setting: press the SET key to select and display "SLP", the green display screen displays the value of the parameter, and select the shift, increment, and decrement keys to set or modify the parameter. This parameter indicates the difference between the alarm point and the master setpoint.

Auto-tuning setting: press the SET key to select and display "Aτ", the green display screen displays the value of the parameter, and select the shift, increment, decrement key to set or modify the parameter; A setting of "00" indicates that autotuning is off, and a setting of "01" indicates that autotuning is started.
8. Lock parameter setting: press the SET key to select and display "OK", the green display screen shows the status of the lock, select the shift, increment, decrement key to set or modify the parameter; If this parameter is set to 00, it is not locked, if it is set to 01, if it is set to lock only parameters other than the master, and if it is set to 02, all parameters are locked. After the parameter is locked, others cannot modify it, and when it needs to be modified, it must be unlocked, that is, it is set to "00".
9. Main control temperature upper limit setting: press the SET button to select and display "SOH", the green display screen will display the value of the parameter, and select the shift, increment, and decrement keys to set or modify the parameter; This parameter indicates that the operating temperature of the main control relay cannot be higher than this value, otherwise, the set temperature of the main control will be invalid
10. Temperature correction setting: press the SET key to select and display "SC", the green display screen displays the value of the parameter, and select the shift, increment, and decrement keys to set or modify the parameter; This function can be used to correct the measurement deviation after a long period of operation of the thermostat. If the measured value is 2°C smaller, you can set this parameter to 02, and if the measured value is 2°C larger, you can set this parameter to -2. When in the second setting area, after pressing the SET button for more than 5 seconds, the system will save the setting parameters and exit the setting state, returning to the normal state. After the setting state is set, if you do not exit the setting state according to the correct operation, the system will automatically exit the setting state after 30 seconds
