• ‘Temperature -’ : Short press to display stop temperature; Long press to set stop temperature by key ‘Temperature +’ and ‘Temperature -’ and display will flashing. It will save automatically after 5 Seconds. (Long press is for 3 seconds).

• ‘Humidity +’ : Short press to display start humidity; Long press to set start humidity by key ‘Humidity +’ and ‘Humidity -’ and display will flashing. It will save automatically after 5 Seconds. (Long press is for 3 seconds).

• ‘Humidity -’ : Short press to display stop humidity; Long press to set stop humidity by key ‘Humidity +’ and ‘Humidity -’ and display will flashing. It will save automatically after 5 seconds. (Long press is for 3 seconds).

• Note: Restore factory settings if keep press ‘Temperature -’ and ‘Humidity +’ until two screen flashing and display ‘888 888’ at the time.

Temperature Control:

• Set Start Temperature: Long press ‘Temperature +’ to set start temperature by key ‘Temperature +’ and ‘Temperature -’ and display will flashing. It will save automatically after 5 seconds and then display current actual temperature.

• Set Stop Temperature: Long press ‘Temperature -’ to set stop temperature by key ‘Temperature +’ and ‘Temperature -’ and display will flashing. It will save automatically after 5 seconds and then display current actual temperature.

Automatic mode selection:

• It is Heating mode if Start Temperature is lower than Stop Temperature.
• It is Cooling mode if Start Temperature is higher than Stop Temperature.

Set Steps:

• Focus:
• Start Temp < Stop Temp (Heating mode, Automatic judgment)
• Start Temp > Stop Temp (Cooling mode, Automatic judgment)
• Method: Please refer to Set Start/Stop Temperature.

Heating mode example:

Control water heater. Heated to 65 Celsius and then stop heating. Reheat when the temperature drops to 50Celsius.

• Step 1 : Set Heating mode, Start Temp < Stop Temp.

• Step 2 : Long press ‘Temperature +’ and Start Temp flashing. Set Start Temperature to 50 Celsius by ‘Temperature +’ and ‘Temperature -’.

• Step 3 : Long press ‘Temperature -’ and Stop Temp flashing.Set Stop Temperature to 65Celsius by ‘Temperature +’ and ‘Temperature -’.

Cooling mode example:

Control farms. Stop ventilation when temperature is 26 Celsius. Refrigeration again when the temperature rises to 30 Celsius.

• Step 1 : Set Cooling mode, Start Temp > Stop Temp.

• Step 2 : Long press ‘Temperature +’ and Start Temp flashing. Set Start Temperature to 30 Celsius by ‘Temperature +’ and ‘Temperature -’.

• Step 3 : Long press ‘Temperature -’ and Stop Temp flashing. Set Stop Temperature to 26Celsius by ‘Temperature +’ and ‘Temperature -’.

• NOTE: Indicator will OFF and Load will not work If the temperature is set incorrectly. So please check if Start Temp and Stop Temp are right after set.

Humidity Control:

• Set Start Humidity : Long press ‘Humidity+’ to set start humidity by key ‘Humidity+’ and ‘Humidity-’ and display will flashing. It will save automatically after 5 seconds and then display current actual humidity .

• Set Stop Humidity : Long press ‘Humidity-’ to set stop humidity by key ‘Humidity+’ and ‘Humidity-’ and display will flashing. It will save automatically after 5 seconds and then display current actual humidity .

• Automatic mode selection : It is Humidification mode if Start Humidity is lower than Stop Humidity. It is Dehumidify mode if Start Humidity is higher than Stop Humidity.

• Humidification mode example: Fresh storage humidification, control humidifier 50% RH to begin humidification, humidify to 80% RH stop.

• Step 1 : Set Humidification mode, Start Hum< Stop Hum.

• Step 2 : Long press ‘Humidity+’ and Start Hum flashing. Set Start Humidity to 50% RH by ‘Humidity+’ and ‘Humidity-’.

• Step 3 : Long press ‘Humidity-’ and Stop Hum flashing. Set Stop Humidity to 80% RH by ‘Humidity+’ and ‘Humidity-’.

• Dehumidify mode example: Dehumidification control system in the workshop, humidity 70% RH starts dehumidification, humidity 40% RH stops dehumidification.

• Step 1 : Set Humidification mode, Start Hum> Stop Hum.

• Step 2 : Long press ‘Humidity+’ and Start Hum flashing. Set Start Humidity to 70% RH by ‘Humidity+’ and ‘Humidity-’.

• Step 3 : Long press ‘Humidity-’ and Stop Hum flashing. Set Stop Humidity to 40% RH by ‘Humidity+’ and ‘Humidity-’.
