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.
2. Upper limit deviation alarm setting: press the SET key to select "SHP", 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 alarm point is higher than the master setpoint.
3. Proportional range setting: press the SET key to select and display "P", 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. The higher the "P" value, the lower the sensitivity of the thermostat's main relay output, and the smaller the "P" value, the higher the sensitivity of the thermostat's main relay output.
4. Integration time setting: press the SET key to select "I", the green display screen displays the value of the parameter, and select the shift, increment, decrement key to set or modify the parameter. The shorter the set integration time, the stronger the integration effect.
5. Differentiation time setting: press the SET key to select "D", the green display screen displays the value of the parameter, and select the shift, increment, decrement key to set or modify the parameter. The longer the differential time set by the instrument, the stronger the correction will be made by differentiation.
6. Proportional period setting: press the SET key to select and display "T", the green display screen displays the value of the parameter, and select the shift, increment, decrement key to set or modify the parameter.
7. 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 completed, if you do not follow the correct operation to exit the setting state, after 30 seconds, the system will automatically exit the setting state, and the parameters you set before will be declared invalid.

Analysis of common fault causes of RKC temperature controller
1. The power indication is normal, but the temperature controller has no screen display. Most of this fault is caused by the heating of the voltage regulator element (7805 or 7812) on the thermostat during long-term use, which causes the solder joint to show a breakpoint, and sometimes it is caused by the phenomenon of virtual soldering at the factory.
2. Temperature controller ...

Precautions for the use of RKC thermostats
fold
When the RKC thermostat comes out, it is a single-loop regulator, that is, it only has a heating function, which is called the basic meter, which is generally sent to the agent, and the agent will expand the multi-channel adjustment and alarm output control function, which is called "changing the meter" in the industry, so as to ensure that there is very little hardware cost.
