Key operation instructions:
1. View parameter method: When the controller is working normally, press and immediately release the “▲” button once to display the temperature setting value, press and immediately release the “▼” button once to display the temperature difference setting value, 2 After the second, the temperature returns to the normal display state.
2. Set the parameter method
When the controller is working normally, press and hold the “S” key for more than 3 seconds to enter the modified parameter mode. The “Set” indicator lights up, and the code “F1” of the first menu item is displayed.
Press “▲” or “▼” to scroll up or down the menu item and display the menu code. Press “S” to display the parameter setting of the current menu. Press and hold the “S” button, then press and hold. The “▲” or “▼” button can be adjusted up or down to display the parameter settings of the current menu. Press and hold the “S” and “▲” or “▼” keys to quickly up or down and display the current menu parameters. After setting, press and release the power button to save the parameter and return to the normal temperature display state.
If there is no key operation within 10 seconds, the parameter modification will not be saved and return to the normal display state. If an error occurs while saving the parameter, “Er” is displayed, and after 3 seconds, it returns to the normal display state.
3. Repair system data:
4. When the machine is powered on, first check if the parameter setting is correct. If the error is detected, “Er” will be displayed. Pressing any button will restore the default parameter setting and work normally. It is recommended to reset the parameter at this time.
Operation and operation instructions
When the controller is working normally, press and hold the power button for more than 3 seconds to turn off the controller. When the controller is turned off, press and hold the power button for more than 3 seconds to open the controller.
When the controller is normal, the digital tube displays the current temperature measurement value and performs automatic recognition conversion of the cooling and heating operation mode.
When the measured temperature ≥ temperature set value temperature difference set value enters the cooling state, the Cool indicator light is on, the cooling relay normally open contact closes: The Cool indicator flashes, indicating that the cooling device is in the press delay protection state: when measuring temperature ≤ temperature The set value of the Cool indicator is off and the normally open contact of the cooling relay is open.
When the measured temperature ≤ temperature set value - temperature difference set value enters the heating state, the Hea indicator light is on, and the heating element is normally open contact closed: when the measured temperature ≥ temperature set value, the Heat indicator, the heating relay normally open contact disconnect.

System code, reason and action:
Sensor fault alarm: When the temperature probe loop is short-circuited or open-circuit fault, the controller starts the probe fault alarm mode, closes all execution states, the buzzer sounds (the individual models are not), the digital tube displays EE, press any key,
The buzzer sound can be eliminated, and after the fault is removed, it returns to the normal working mode.
Over temperature limit alarm: When the temperature measurement exceeds the temperature measurement range, the controller starts the over temperature limit fault.
In the alarm mode, all execution states are turned off, the buzzer sounds, the digital tube displays HH, and any key is pressed to eliminate the buzzer sound. When the temperature returns to the normal measurement range, it returns to the normal working mode.
Danger:
1. Strictly distinguish the sensor lead, power cord and output relay interface, can not be connected incorrectly, the breaker can not be overloaded.
2. All wiring changes must be made with the power off.
Note:
1. This controller is forbidden to use in water or excessively humid environment. It is forbidden to use in high temperature, strong electromagnetic interference and strong corrosive environment.
2. The supply voltage should be consistent with the voltage marked on the controller and ensure the stability of the supply voltage.
3. To avoid possible interference, it is recommended to keep the sensor leads at an appropriate distance from the power line.
