• Click the [AP Mode symbol] icon to enter device adding interface, 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 Setting in your smart phone, select the "SmartLife-XXXX" to directly connect to the router without putting in password.
• Go back to app to enter into the automatic connection interface.

④ Click "Done" after adding device successfully and enter into device controlling interface.

⑤ In the temperature control mode, user can set control function via APP.

App Interface Details:

The app interface displays: Device Name, Back to Home Page, PV: Current Temperature, Control Mode, SV: Temperature Setting Value, Temperature Trend Diagram, Menu Setting. The 'Setting' screen shows options like Heating Difference Value (HD), Cooling Difference Value (CD), High Temperature Alarm, Low Temperature Alarm, Refrigeration Delay, Temperature Calibration, and Temperature unit switch (°C/°F).

06 Control Function Instructions

6.1 Button Operation Instructions

6.1.1 Button Function in Normal Operation Mode

• Quickly press ⬇️: PV shows HD (heating difference value); Short Press ⬇️ again: PV shows CD (cooling difference value). Returns to normal display after 3 seconds of no operation or pressing SET.
• Quickly press SET: Enter quick setting temperature value mode. SV displays current control setting value and flashes. Quickly press ⬆️ or ⬇️ to increase/decrease the setting value. Long press ⬆️ or ⬇️ for rapid adjustment. Press SET to confirm and exit. Exits automatically after 10 seconds of no operation, saving the value.

6.1.2 Button Function in Setting Mode

Press SET for 2 seconds to enter setting mode. PV shows menu code "TS", SV shows the corresponding setting value. Press SET to scroll down the menu item and save the parameters of the previous menu item. Press ⬆️ or ⬇️ to change the current setting value. Exits and saves after 30 seconds of no operation or a 2-second SET press, returning to normal operation mode.

6.2 Menu Setting Flow Chart

The menu setting process starts by pressing "SET" for over 2 seconds to enter parameters setting mode. The sequence is: TS (Temperature Set Value), HD (Heating differential value), CD (Cooling difference value), AH (Alarm High Limit), AL (Alarm Low Limit), PT (Compressor Delay Time), CA (Temperature Calibration), CF (Temperature Unit). The system exits and returns to "Working normally" if no key is pressed for 30 seconds or "SET" is pressed for over 2 seconds.

6.3 Setting Menu Instruction

6.4 Control Function Instruction

When the controller works normally, PV screen shows the measured temperature, meanwhile the SV screen shows the set temperature. It recognizes and converts from heating to cooling mode automatically. HEATING socket for heating output, the red LED indicator ? showing heating status. While COOLING socket for cooling output, the green LED indicator ? showing cooling status.

6.4.1 Instructions for Setting Temperature Control (TS, HD, CD)

6.4.1.1 Normal Temperature Control

Heating: When measured temperature PV ≤ TS (Temperature Setting Value) – HD (Heating difference value), the controller will enter the heating state, the red LED ? is on, HEATING output works. When the measured temperature PV ≥ TS (Temperature Setting Value), the red LED ? is off and the HEATING output turns off.

Cooling: When the measured temperature PV ≥ TS (Temperature Setting Value) + CD (Cooling difference value), the controller will enter the cooling state, the green LED ? is on, COOLING output works; the green LED ? flashes, indicating that the cooling device is in the state of the Compressor delay protection. When PV (measured temperature) ≤ TS (temperature setting value), the green LED ? is off and the COOLING output turns off.

Example: Setting TS=25.0°C, CD=2.0°C, HD=3.0°C. When the measured temperature value ≤ 22°C (TS-HD), the controller will enter the heating state; when the measured temperature value ≥ 25°C, the heating will stop; when the measured temperature value ≥ 27.0°C (TS+CD), the controller enters the cooling state; when measured temperature value ≤25.0°C, cooling will stop.

6.4.1.2 Special Temperature Control

If there is no need to judge the return difference in heating or cooling when power on or exiting the setting state, then it directly compares with TS. For example: When power on or exiting the setting state, TS=25.0°C, CD=2.0°C, HD=3.0°C. If PV (measured temperature value) >25.0°C, it enters the cooling state. When PV (measured temperature value) ≤25.0°C, the cooling stops. Then return to normal temperature control. When PV (measured temperature value) <25.0 °C, it enters the heating state, when PV (measured temperature value) ≥ 25.0 °C, heating stops, and then return to normal temperature control.

6.4.2 Alarm High / Low Temperature Limit Settings (AH,AL)

When measured temperature ≥ AH (high temperature limit alarm), then AH flashes alternately with the current temperature, meantime buzzer will "bi-bi-Biii" alarm, until the temperature <AH, buzzer off and return to normal display and control. Or press any button to turn the buzzer alarm off only. When measured temperature ≤ AL (low temperature alarm), then AL flashes alternately with the current temperature, meantime buzzer will "bi-bi-Biii" alarm, until the temperature >AL, buzzer off and return to normal display and control. Or press any button to turn the buzzer alarm off only. High and low temperature limit alarm will be pushed to mobile APP and remind the customer that the product is in alarm state.

6.4.3 Compressor Delay Time(PT)

In the cooling mode, when the power is turned on for the first time, if PV (measured temperature value) ≥ TS (Temperature setting value) + CD (Cooling difference value), it will not start cooling immediately, but waiting for a delay time(PT). When two adjacent of cooling starting intervals are greater than the delay time, it will immediately start cooling; When two adjacent of cooling starting intervals are less than the delay time, it needs to operate the remaining delay time to start the cooling. Delay time will start counting from the cooling output off.

6.4.4 Temperature Calibration(CA)

When the measured temperature deviates from the standard temperature, the temperature calibration function can be used to make the measured value of the instrument consistent with the standard value. The calibrated temperature = the measured temperature + the calibration value.

6.4.5 Fahrenheit or Celsius Settings (CF)

User can set the display unit to Fahrenheit or Celsius according to their habits. The default temperature is Fahrenheit. If you need to display the unit in Celsius, then set the CF to C. Please note that when the CF changes state, all setting values are restored to the default setting and the buzzer gives a short beeping prompt.

07 Exception Handling

7.1 Probe Fault

When the temperature sensor circuit is short-circuited or open-circuit fault, the controller starts the probe fault mode, it will close all execution states, the buzzer sounds and the digital tube displays ER. Then press any button to eliminate the buzzer sound. After the fault is removed, it will return to the normal working mode.

7.2 Power Off or Disconnected State

When the controller is powered off or disconnected, the mobile APP will still show online state, and the disconnected state will be showed after 1 to 3 minutes.
