Wifi thermostat through wireless moble communication transmission after network configuration. RS485 communication wireless thermostat through the radio frequency communication via RF.RS485 is known for being able to be used effectively over long distances and in electrically noisy environments. due to this and it being able to transmit data over long distances.

1.The wifi thermostat and router are too far to get the signal, you may amplify the transmitted signal or move the two closer. 2.Replace a new wifi thermostat when you try to configure the network through the hotspot and it fails to connect.

When the LED screen of your water purifier doesn't light up, there're maybe some problems with the power or socket. We offer corresponding solution to you. Please click to read more.

1、When the controller cartridge progress bar shows red, please replace the cartridge in time. 2、Open the middle gland plate of the exchange core in the direction as shown. 3、Take out the cartridge in the direction of the figure and replace it. 4、Put the replaced cartridge into the corresponding slot and cover the exchange core gland. 5、Open the cartridge setting page of the controller and press and hold the cartridge progress bar for 5 seconds to reset the cartridge balance, and the display shows 100% that the reset is successful. Note: Steps 1 and 5 are required for CLS4.0S LCD controller, if you purchase other controllers, please refer to the manual of the controller.

1.The host does not run (1) Check whether the power supply is normal (2) check whether the power connected to the machine is open (3) confirm whether the machine is in the power on state (4) confirm whether the fuse is damaged 2. High noise (1) Check whether the host is firmly installed (2) check whether the host anti-vibration pad has been added (3）Check whether the motor is faulty (4）Check whether the cartridge needs to be replaced (5) Check whether the outdoor air outlet is blocked 3. Small air volume (1) Check whether the outdoor air outlet is blocked (2) Check whether the filter needs to be replaced (3) Check whether the indoor air outlet needs to be adjusted

Energy saving mode: The air volume of exhaust air and fresh air are equal. Default wind speed is low speed. Haze removal mode: The fresh air is high speed, the exhaust air is low speed, and the wind speed shows high speed. Sleep mode: Both fresh air and exhaust air are low speed, wind speed shows low speed. Auto mode: Automatically adjust the airflow level according to the indoor CO2 and PM2.5 concentration. User can set the corresponding value in the setting page. For example, when PM2.5 is set to High > 100 > Medium > 35 > Low and C02 is set to High > 1500 > Medium > 700 > Low, when the air quality sensor detects PM2.4 > 100 and CO2 is between 700 and 1500, the wind speed is high.

Enthalpy exchangers are particularly useful in climates where there are significant temperature and humidity differences between the indoor and outdoor environments. Apart from transferring sensible heat (temperature), they also transfer latent heat (moisture) between the airstreams, providing the benefits of both heat and moisture recovery.

When two people sleep for seven hours, their sweating and breathing produce approximately 7.5 to 8 decilitres of moisture and about 150 to 200 litres of carbon dioxide. They also release some 250 to 300 watts of heat to indoor air. If the moisture content of indoor air rises too high, the moisture condensates in the windows or in the structures of the cold external wall. Structures that have become moist are breeding grounds for microbes and mould fungi, which will before long cause damage to the structures. Almost all fungal mycelia grow at a relative moisture of more than 80% and in normal room temperature. Efficient ventilation removes the carbon dioxide and moisture load as well as smells, taking them out of the house.

The default setting of filter life is 6 months(which can be reset in WeChat). After using for 6 months, the filter icon will flash to remind the user to replace the filters. After replacing the filter, long press the filter button for 5 seconds to reset the time.

If the area of a computer room is 60 sq meter(S=60), the net height is 3 meters(H=3), and there are 10 persons(N=10) in it. If it is calculated according to “Personal fresh air consumption”, and assume that:Q=70, the result is Q1=N*Q=10*70=700m³/h If it is calculated according to “Air change per hour”, and assume that: P=5, the result is Q2=P*S*H=5*60*3=900m³/h Since Q2＞Q1，Q2 is better for selecting the unit. As to special industry such as hospitals(surgery and the special nursing rooms), labs, workshops, airflow required should be determined in conformity with regulations concerned.
