View parameter method
When the thermostat is working normally, press and release the key once to display the temperature set value; press and release the key once to display the temperature difference set value. After 3 seconds, the temperature returns to the normal display state.
Setting Parameter Method:
When the thermostat is working normally, press and hold the button for more than 3 seconds to enter the modified parameter mode. The “Set” indicator lights up, the digital tube displays the code “F1” of the first menu item, and press the or key to up or down the code of the menu item. Press the key to display the parameter setting value of the current menu, press and hold the key, then press the or key to increase or decrease the parameter setting value of the current menu; press and hold the key, and press the or key to quickly increase the speed. Or down and display the parameter settings of the current menu.
Press and at the same time to restore the parameters to the factory settings.
When the thermostat is working normally, press and hold the power button for more than 3 seconds to turn off the thermostat. When the thermostat is off, press and hold the power button for more than 3 seconds to open the thermostat.
When the thermostat is working normally, the digital tube displays the current temperature measurement value, and performs automatic recognition conversion of the cooling heating operation mode.
When the measured temperature ≥ temperature set value + temperature difference set value, enter the cooling state, the Cool indicator light is on, the cooling relay normally open contact is closed; the Cool indicator flashes, indicating that the cooling device is in the press delay protection state; when measuring the temperature ≤ temperature set value, the Cool indicator is off, and the normally open contact of the refrigeration relay is disconnected.
When the measured temperature ≤ temperature set value - temperature difference set value enters the heating state, the Heat indicator light is on, the heating relay normally open contact is closed; when the measured temperature ≥ temperature set value, the Heat indicator is off, the heating relay normally open contact disconnect.
Indicator Status Description:
Indicator function comment
Cool indicator light: cooling work; off: cooling off; flashing: press delay Cool, Heat two lights can not be lit at the same time
Heat indicator light: heating work; off: heating off
Set indicator Lights up: parameter setting status
Menu Function Description:
Menu identification Menu function Setting range Factory setting
F1 temperature setting -40.0~99.9°C 10.0°C
F2 temperature difference setting value 0.3~10.0°C 0.5°C
F3 press delay 1~10 minutes 3 minutes
F4 temperature correction -10.0~10.0°C 0°C
Repair System Data:
After the thermostat is powered on, first check whether the parameter settings are correct. If an error is detected, “Er” is displayed. Pressing any key will restore the default parameter settings and work normally. It is recommended to reset the parameters at this time.
System Code, reason and action:
Sensor fault alarm: When the temperature probe loop is short-circuited or open-circuit fault, the thermostat starts the probe fault alarm mode, closes all execution states, and the digital tube displays “EE”. After the fault is cleared, press any key to return to the normal working mode.
Over-temperature alarm: When the temperature measurement exceeds the temperature measurement range, the thermostat starts the over-temperature limit fault alarm mode, and all execution states are turned off. The digital tube displays “HH”. When the temperature returns to the normal measurement range, press any key. Return to normal working mode.
1. Strictly distinguish the sensor lead, power line and output relay interface, can not be connected incorrectly, the relay can not be overloaded;
2. All wiring changes must be made with the power off.
1. This thermostat is forbidden to be used in water or excessively humid environment. It is forbidden to use in high temperature, strong electromagnetic interference and strong corrosive environment.
1. The supply voltage should be consistent with the voltage marked by the thermostat and ensure the stability of the supply voltage;
2. To avoid possible interference, it is recommended that the sensor leads be at an appropriate distance from the power line.
