It will enter the Smartconfig configuration state by default. You can short press to switch the WIFI Smartconfig configuration state and the AP mode. If you change the Wi-Fi state, it will take about 5 seconds to display the corresponding LED symbol and state, because of the Wi-Fi module data processing.

Add device in quick connection:

Plug the device in the socket and make sure that the device is in Smartconfig.
Configuration state (the LED symbol is flashing, interval flashing 250ms). Click “Confirm indicator rapidly blink” and then select Wi-Fi network, enter Wi-Fi password, click “confirm” to enter connection process.
The device only supports 2.4GHz Wi-Fi router.

Add device in AP mode:

Plug the device in the socket and make sure that the device is in the AP Configuration State (the LED symbol is flashing slowly, interval flashing 1500ms).
Click “Confirm indicator slowly blink” and then select Wi-Fi network, enter Wi-Fi password, click “confirm” to enter connection process.
Press “Connect now” and it will go to your WLAN settings in your smartphone, select the “SmartLife-XXXX” to directly connect to the router without providing a password.
Go back to app to enter into the automatic connection interface.

④ Click “Done” after device is added successfully and enter into device controlling interface.
⑤ In the temperature control mode, user can set control function via APP.

Button Instruction

Factory Reset
Hold the “ ” button to power on, the buzzer will beep once, and all parameters will restore to factory settings.
Button Instruction in the Setting Mode
When the controller is working normally, press SET key for 2 seconds to enter parameter setting mode. PV window displays the first menu code “TS1”, while SV window displays the setting value. Press the SET button to scroll down the menu and save the previous menu parameters, press the “” WIFI or “” button to change the current setting value. If there is no button operation within 30 seconds or long press the “SET” button for 2 seconds in the setting state, it will exit and save the setting state, then return to the normal working mode.

Menu Setting Flow Chart

Setup Menu Instruction

When TR=1, the time mode function is on, the menu settings are as follows.

Control Function Instruction

Temperature Control Instruction in the Normal Mode (TS1, DS1, TR=0)
When the controller is working normally, PV window displays the measured temperature, SV window displays temperature set value.
When the measured temperature PV ≥ TS1 (Temperature Set Value1), the WORK indicator is off, the output sockets turn off; When the measured temperature PV ≤ TS1 (Tempera-ture Set Value1)-DS1 (Heating Differential Value 1), the WORK indicator is on, and the output sockets turn on.
For example, TS1=25.0°C, DS1=3.0°C, when the measured temperature ≤ 22°C (TS1-DS1), the output sockets turn on; when the measured temperature ≥ 25°C (TS1), the output sockets turn off.
Temperature Control Instruction in the Timer Mode (TS1, DS1, TR=1 , TS2, DS2, TAH, TAM, TBH, TBM, CTH, CTM)
When TR=0, the timer mode function is off, the parameters TS2, DS2, TAH, TAM, TBH, TBM, CTH, CTM don’t show up in the menu.
When TR=1, the Timer Mode is on. Time A~Time B~Time A is a cycle, 24 hours.
During Time A~Time B, the controller runs as TS1 (Temperature Set Value1) and DS1 (Heating Differential Value1); during Time B~Time A, the controller runs as TS1 (Temperature Set Value2) and DS1(Heating Differential Value2).
For example: Set TS1=25, DS1=2, TR=1, TS2=18, DS2=2, TAH=8, TAM=30, TBH=18, TBM=00, CTH=9, CTM=30, CTH and CTM are the current time setting, the setting time is 9:30.
During 8:30-18:00 (Time A~Time B), the temperature controls between 22°C (TS1-DS1)~25°C (TS1);
During 18:00-8:30 (Time B~Time A), the temperature controls between 16°C (TS2-DS2)~18C (TS2).

High/Low Temperature Alarm (AH,AL)
When the measured temperature ≥ High Temperature Alarm (AH), it will alarm and turn off heating output. The PV window will display “AH” and the measured temperature at the 1Hz frequency alternately , buzzer will “Bi-Bi-Biii” when ALM=ON, until the measured temperature < AH, buzzer will be off and return to normal display and control. Or press any button to turn the buzzer alarm off;

When the measured temperature ≤ Low Temperature Alarm (AL), it will alarm. The PV window will display “AL” and the measured temperature at the 1Hz frequency alternately, buzzer will “Bi-Bi-Biii” when ALM=ON, until the temperature > AL, buzzer will be off and return to normal display and control. Or press any button to turn the buzzer alarm off.
Note: The Low Temperature Alarm (AL) should be less than the High Temperature Alarm (AH). The high or low temperature alarm will be pushed to mobile APP and remind the user that the device is in alarm state.

Temperature Calibration (CA)
When there is deviation between measured temperature and actual temperature, the temperature calibration function can be used to calibrate the measured value and make it consistent with the standard value, the calibrated temperature = the measured temperature value + the calibration value.

Display in Fahrenheit or Celsius unit (C/F)
Optional setting the display unit as Fahrenheit or Celsius. The default temperature unit is Fahrenheit. In need of displaying in Celsius , set CF value as C.
Note: When CF is changed, all setting values will be restored to the default setting and the buzzer will beep once.

Buzzer Sound ON/OFF Under Abnormal Alarm (ALM)
Users can choose whether to turn on the sound function of the buzzer when an abnormal alarm occurs according to actual use. When choosing ON, the buzzer will make a sound, when choosing OFF, the buzzer will close the sound when there is abnormal alarm.

Error Situation

Probe Error
The PV window show Er when the probe is not plugged in properly or there is short circuit inside the probe. When ALM=ON, the buzzer will kept beeping, the sound can be cut off by press any button.

Time Error
When time abnormal, PV window indicate Err. When ALM=ON, the buzzer will kept beeping, the sound can be cut off by press any button.
Time Reset Error
When TR=1, when the device is power-on again after power off, and when PV window alternately display the current temperature and TE at 1 Hertz frequency. If ALM=ON, the buzzer will go off every two seconds which mean the timer should be reset. You can press any button to stop the alarm, if long press for 2 seconds, it will enter to the setting menu and skip to CTH menu code, setting the CTH and CTM value then save the parameter, the device will back to normal operation; normal operation can also be restored by tapping the synchronization time via the app.
