strongParameter setting methodstrong

When the temperature controller works normally press and hold the key for more than 3 seconds to enter the parameter modification mode The Set indicator lights up and the Nixie tube displays the code F1 of the first menu item Press the or key to increase or decrease the code of the menu item and press the key to display the parameter setting value of the current menu Press and hold the key and then press the or key briefly to increase or decrease the code and display the parameter setting value of the current menu Hold down the key while holding down the or key for a long time to quickly adjust up or down and display the parameter settings of the current menu

Press and hold the and keys at the same time then power on and the parameters Factory reset

strongOperating instructionsstrong

When the thermostat is working normally holding down the power button for more than 3 seconds will turn off the thermostat When the thermostat is turned off holding down the power button for more than 3 seconds will turn on the thermostat

When the temperature controller works normally the Nixie tube displays the current temperature measurement value and automatically recognizes and converts the cooling and heating working mode

When the measured temperature is the temperature set valuethe temperature difference set value it enters the cooling state the Cool indicator light is on and the normally open contact of the cooling relay is closed The Cool indicator light flashes indicating that the refrigeration equipment is in the delayed protection state of the compressor When the measured temperature is the set temperature value the Cool indicator light goes out and the normally open contact of the refrigeration relay opens

When the measured temperature is the temperature set value temperature difference set value it enters the heating state the Heat indicator light is on and the normally open contact of the heating relay is closed When the measured temperature is the set temperature value the Heat indicator light goes out and the normally open contact of the heating relay opens

1 Temperature setting ambient temperature required by the user Users can adjust it on the temperature controller or APP with an adjustment range of 40 to 999 degrees Celsius

2 Temperature difference setting Set the difference between the target temperature for heating or cooling when operating at a constant temperature For example if the target temperature is 40 degrees the temperature difference is set to 2 degrees After heating to 40 degrees stop heating and enter the constant temperature mode When the temperature drops to 38 degrees enter the heating mode again The difference in this value is 2 degrees This value can be adjusted through the host or APP with an adjustment range of 0 to 10 degrees Celsius

3 Compressor delay This function is generally used for compressor cooling If the temperature controller is used for refrigerators and freezers this value must be set According to the return pressure of the compressor the general setting value is 36 minutes which can be adjusted through the host or APP with an adjustment range of 0 to 10 minutes

4 Temperature correction used to correct the temperature value currently detected by the temperature controller with a correction range of 0 to 10 degrees Celsius

Fix system data

After the temperature controller is powered on first check if the parameter settings are correct If an error is detected it will display Er At this time pressing any key will restore the default parameter settings and work normally It is recommended to reset the parameters at this time

System code cause and action

Sensor fault alarm when the temperature probe circuit has short circuit or open circuit faults the temperature controller starts the probe fault alarm mode closes all execution states and the Nixie tube displays EE After the fault is removed press any key to return to the normal working mode

Over temperature limit alarm when the temperature measurement exceeds the temperature measurement range the temperature controller starts the over temperature limit fault alarm mode closes all execution states and the Nixie tube displays HH When the temperature returns to the normal measurement range press any key to return to the normal working mode 18b20

strongSafety rulesstrong

Danger

1 Strictly distinguish between sensor leads power lines and output relay interfaces and do not connect them incorrectly Relays should not be overloaded

2 All wiring changes must be made with the power disconnected

Warning

1 This temperature controller is prohibited from use in water or excessively humid environments as well as in high temperatures strong electromagnetic interference and corrosive environments

Attention

1 The power supply voltage should be consistent with the voltage marked on the temperature controller and ensure the stability of the power supply voltage

2 To avoid possible interference it is recommended to maintain an appropriate distance between the sensor lead and the power line
